Best LinkedIn Contact Finder Tools in 2026: 14 Chrome Extensions Compared on Accuracy, Credits and Compliance
Turn this article into takeaways for your work.
Each assistant summarizes the article only for you and suggests best practices for your work.
If you want one LinkedIn contact finder that covers email and phone for a small team, start with Lusha, ContactOut or SignalHire. If your buyers are in Europe and you need a vendor with a documented compliance program, Cognism is the safer pick. If you're cost-sensitive and email is enough, Hunter, Skrapp.io and Snov.io cost the least. And if you want the cheapest way to try phone reveals before you commit, Apollo.io's free plan and Prospeo's free plan are the easiest places to test.
This page is about one narrow product type: Chrome extensions that sit on top of LinkedIn and Sales Navigator profiles and reveal a work email, a personal email or a phone number with one click. We compare 14 of them on three things buyers tend to get wrong. First, data accuracy: what each vendor claims, how it verifies, and what happens when a reveal is wrong. Second, credit models: what a phone number costs compared to an email, what "unlimited" really means, and what rolls over. Third, compliance: LinkedIn's own rules, GDPR and its first big extension fine, US and UK phone consent, and what to ask a vendor before you upload a single export to your CRM.
For the broader category (databases, intent, enrichment suites), start with the best sales intelligence tools in 2026. This page does not repeat that comparison. It zooms into the extension layer, where most of the day-to-day cost and most of the legal exposure sit.
Key Facts
- Sales reps spend 40% of their week selling, and the same Salesforce report says they spend almost a full day of the workweek on prospecting, which is why contact reveal tools sell so well.
- The same Salesforce State of Sales report found that 46% of sales pros with agents say data quality issues hurt their sales, so a reveal that returns a stale address costs more than the credit.
- The median US worker had been with their current employer for 4.1 years in January 2026, so a meaningful share of any contact list changes jobs every year.
- France's data regulator fined Kaspr EUR 240,000 in December 2024 over a LinkedIn contact extension, the first big GDPR fine aimed squarely at this product type.
- US telemarketing violations carry civil penalties of up to $53,088 each, and the TCPA lets individuals recover $500 per violation.
What Is a LinkedIn Contact Finder (and What It Isn't)?
A LinkedIn contact finder is a browser extension, usually for Chrome, that reads the profile or Sales Navigator page you have open and matches it against the vendor's own database. You click, the extension spends a credit, and a work email, personal email or mobile number appears beside the profile. Some tools also push the record into your CRM or a sequence in one more click.
Two points are easy to miss. The data usually does not come from LinkedIn itself. It comes from the vendor's database, which the vendor built from many sources, including its own users' address books and public web pages. And the extension is a convenience layer: the real product is the database behind it, the verification step in front of it and the credit meter between the two.
That's why the comparison below puts the credit model and the compliance posture next to the accuracy claim. A tool with a great hit rate and a rule-breaking data source is a liability, and a tool with clean data and a 20x phone credit multiplier will drain your plan before the first week of outbound is done.
Quick Comparison Table
| Tool | Best For | Starting Price | Key Strength | Key Limitation |
|---|---|---|---|---|
| Lusha | Small teams that want email and phone with clear plans | Free 40 credits/mo; Starter $49.90/mo monthly | Phone and email accuracy claims published, rollover on monthly plans | Phone costs 5 credits, so Starter yields few numbers |
| Apollo.io | Teams that want data plus sequencing in one seat | Free plan; Basic $49/seat/mo annual, $65 monthly | Largest free credit pool, pooled team credits | Phone costs 8 credits and credits don't roll over |
| ContactOut | Recruiters and SDRs who need personal emails | Free 5/day; Email plan $49/mo monthly | Unlimited email on paid plans, personal emails | Single seat per company, phones only on the higher plan |
| SignalHire | Recruiters and teams with many users | Free 5 credits; from $49/mo monthly | Unlimited users, credits charged only on a hit | No published accuracy percentage |
| RocketReach | Teams that want both lookups and an API | Essentials $49/mo monthly | Lookups refunded when nothing verified is found | Annual "unlimited" is capped, region-based prices |
| Kaspr | European prospecting with phone | Free tier; Starter EUR 45/user/mo annual | Strong EU coverage, phone allowances | Fined by CNIL, so vet its processing carefully |
| Cognism | Regulated or EU-heavy outbound teams | Pricing on request | Do-not-call screening, phone-verified mobiles | Pricing is opaque and aimed at larger budgets |
| LeadIQ | SDR teams that capture to CRM | Free 50 credits; Pro from $15/mo annual | Five users included, CRM capture workflow | Phone costs 10 credits |
| Prospeo | Cheap verified emails and mobiles | Free 100 credits/mo; Starter $49/mo monthly | Low entry price, 98% accuracy claim | Credits don't roll over |
| Findymail | Teams that want a bounce guarantee | Individual $99/mo | Charges only verified results, refund on bounces | No annual price printed, phone is 10 credits |
| Snov.io | Teams that also want outreach automation | Starter $39/mo monthly | Unlimited seats, flat plans | Email-centric, conflicting database size claims |
| Skrapp.io | Low-budget email finding | Free 50 credits; $29/mo annual | Invalid and unknown results cost nothing | Email only, small user caps |
| Hunter | Domain searches and email verification | Free 50 credits/mo; Starter $49/mo monthly | Unlimited users, flat accounts | No phone numbers |
| Datanyze | Existing ZoomInfo-family buyers | Pro 1 $29/mo monthly | Simple per-user reveal pricing | Free tier is a 90-day trial only |
1. Lusha: the plan-based default for small teams
Lusha is the extension most reps have heard of, and the pricing page is easy to read. The free plan gives 40 credits a month for one user with no card. Starter is $49.90 a month billed monthly or $37.45 a month billed annually ($449.10 a year) for 400 credits a month. Pro is $69.90 monthly or $52.45 a month billed annually for 600 credits and two seats, and Premium is $399.90 monthly or $299.95 a month billed annually for 3,400 credits and five seats. Past five users, it's a sales conversation.
The credit math is what matters. An email costs 1 credit and a phone number costs 5, so a Starter plan is 400 emails or 80 phone numbers, not both. Monthly plans roll unused credits over up to twice the monthly cap, while annual credits arrive upfront and reset at year end. Seats are bundled in the plan rather than priced per user, which is unusual in this category.
On accuracy, Lusha says its database holds 515M+ contacts with 98% email accuracy and 85% (US) and 86% (global) phone accuracy. Treat those as vendor claims. On compliance, the site lists GDPR (ePrivacyseal), CCPA (TrustArc) and SOC 2 Type II, and the plan comparison includes a do-not-call row, which is the sort of detail a phone-heavy team should ask about by name.
| Pros | Cons |
|---|---|
| Flat plans with seats bundled | Phone is 5x an email, so numbers burn credits fast |
| Rollover on monthly plans | Annual credits reset at year end |
| Published phone and email accuracy claims | Over five users, pricing moves to sales |
Best for: a team of one to five that wants both emails and phones and would rather buy a plan than a meter.
2. Apollo.io: data, sequences and a big free pool
Apollo isn't only an extension, but its Chrome tool is one of the most used, and the economics differ from Lusha. Pricing is per seat: Free, Basic at $49 per seat per month billed annually or $65 monthly, Professional at $79 annual or $99 monthly, and Organization at $119 annual with a three-seat minimum. The free plan carries 900 credits per seat per year, granted monthly (75 a month), and the paid plans carry many more.
Credits are pooled across the team and do not roll over. An email costs 1 credit, a phone number 8, and "unlimited" features sit under a fair use policy with no published cap. Apollo says its database holds 240M+ contacts and 30M+ companies with 98% email accuracy, and the same page states GDPR compliance on a legitimate-interest basis along with SOC 2 Type II and ISO 27001. Ask Apollo for its CCPA and do-not-call handling in writing before you dial from it.
If you're comparing it with the rest of the field, the best Apollo alternatives page covers sequencing and dialer trade-offs in more depth.
| Pros | Cons |
|---|---|
| Biggest free credit pool in the category | Phone is 8 credits |
| Contact data and sequences in one tool | No rollover, including add-on credits |
| Pooled team credits | Per-seat pricing grows with headcount |
Best for: teams that will send sequences from the same tool they find contacts in.
3. ContactOut: personal emails and recruiter-style searches
ContactOut built its name finding personal emails for recruiting, and SDRs use it for the same reason: a personal address sometimes beats a bounced work one. The free plan allows 5 emails, 5 phones and 5 exports per day. The Email plan is $49 a month billed monthly or $468 a year billed annually with 300 exports a month, and the Email and Phone plan is $99 a month billed monthly or $948 a year billed annually with 600 exports a month. Paid plans are limited to one user per company, and there's a toggle that takes half off if you exclude US and UK data. If its seat or export limits pinch, see the ContactOut alternatives.
Read the fine print on "unlimited". The terms cap fair use at 2,000 email credits and 1,000 phone credits per account per month. ContactOut claims 800M profiles, 150M personal emails and 100M direct dials, with 99% accuracy (the pricing page says 700M+), and states GDPR and CCPA compliance and SOC 2. Personal emails raise the consent bar in the EU and UK, so decide in advance whether you'll use them at all.
| Pros | Cons |
|---|---|
| Personal and work emails | One seat per company on paid plans |
| Unlimited emails within fair use | Phones only on the higher plan |
| Half-price option that excludes US and UK data | Profile count differs between pages |
Best for: recruiters and outbound reps who need personal emails and can live with a single seat.
4. SignalHire: unlimited users, charged only on a hit
SignalHire is the pick when several people share one budget. It doesn't charge per seat: unlimited users on every plan with shared credits. The free plan gives 5 credits, or 10 credits a month with the extension installed. Email plans start at $49 a month for 600 credits, or $469 a year for 7,200 credits, and phone plans start at $49 a month for 300 credits, or $469 a year for 3,600. Unlimited tiers exist at $79 a month for emails and $99 a month for phones, capped by a fair usage limit of 2,000 credits a month.
One credit buys one contact and is spent only if at least one email or phone comes back, which protects you from paying for misses. SignalHire says it holds 900M+ profiles and 30M+ companies but publishes no accuracy percentage, and it states GDPR and CCPA compliance in its privacy FAQ. Rollover isn't stated, so confirm it.
| Pros | Cons |
|---|---|
| No per-seat charge | No published accuracy figure |
| Pay only when a result is returned | Rollover not stated |
| Separate phone and email plans | Fair usage cap on "unlimited" |
Best for: recruiting teams and agencies with many users and uneven usage. Already on it and weighing a switch? Compare the SignalHire alternatives.
5. RocketReach: lookups, exports and an API
RocketReach prices by seat and splits usage into lookups and exports, which confuses first-time buyers. Monthly plans are Essentials at $49, Pro at $99 and Ultimate at $209, with lookups capped at 100, 250 and 1,000 a month. Annual plans (US list) start at $399 a year for Essentials, $899 for Pro and $1,699 for Ultimate, and annual prices differ by region.
Annual plans are "unlimited" but capped by a fair use limit of 10,000 lookups a month, and Essentials returns email only while Pro and Ultimate return email and phone. The trap is exports: API lookups, bulk lookups, CSV, list upload and CRM pushes consume exports, not lookups, and annual exports are 1,200, 3,600 and 20,000. A lookup is charged only if a verified email or phone is found. RocketReach says it covers 700M professionals and 60M companies with 98% accuracy, and lists SOC 2 Type II and ISO 27001.
| Pros | Cons |
|---|---|
| Lookup refunded if nothing verified | Exports are a second meter to watch |
| API access and bulk features | Annual price varies by region |
| Free account with 5 lookups | Per-seat pricing |
Best for: teams that need an API or bulk exports alongside the extension.
6. Kaspr: strong EU data, with a fine on file
Kaspr is built for European B2B prospecting and prices per user. The free tier gives 15 B2B email credits, 5 phone credits and 5 direct email credits a month. Starter is EUR 45 per user a month annually or EUR 59 monthly (also listed in USD and GBP), with 100 phone credits a month. Business is EUR 79 annually or EUR 99 monthly with 200 phone and 200 direct email credits a month. Phone add-ons start at EUR 0.35 each. B2B email is "unlimited" but capped at 10,000 credits per account per month.
Kaspr says it holds 200M+ European B2B contacts and re-validates emails every two months, and Cognism owns Kaspr. The reason to read the compliance section below before buying: in December 2024 France's CNIL fined Kaspr EUR 240,000 for collecting contact details of LinkedIn members who had limited their visibility, among other breaches. The regulator ordered corrective changes with a six-month compliance deadline, so ask Kaspr what it changed.
| Pros | Cons |
|---|---|
| Phone allowances built into plans | EUR 240,000 CNIL fine |
| Rollover on paid plans | Compare table and plan cards disagree on some caps |
| Good European coverage | Per-user pricing |
Best for: EU-focused outbound teams that have reviewed the CNIL decision with their legal counsel. Teams leaving it can compare the Kaspr alternatives.
7. Cognism: the compliance-first option
Cognism doesn't print prices: Standard and Pro plans, five seats included, credits per seat. One credit reveals one contact, a re-view is free, and you're charged again only if the contact changes jobs. A reported structure is roughly $15,000 for the platform plus about $1,500 per user a year on Standard and about $25,000 plus about $2,500 per user on Pro (reported). Source: Amplemarket citing Vendr. Confirm any figure with Cognism.
What you're paying for is the compliance program. Cognism says it screens against do-not-call lists including UK TPS and CTPS, the US, Australia and several EU countries, is ISO 27001 and ISO 27701 certified, holds SOC 2 Type II and is registered as a California data broker. It also says phone-verified mobiles deliver up to 3x higher connect rates and that Director-and-above data is refreshed every 30 days. The best ZoomInfo alternatives page puts Cognism in the larger-budget context.
| Pros | Cons |
|---|---|
| Do-not-call screening across many countries | Pricing on request |
| ISO 27701 and SOC 2 Type II | Budget is aimed at teams, not individuals |
| Re-view is free | No free trial, demo and data sample only |
Best for: regulated industries and EU-heavy teams where a documented compliance program outweighs the price.
8. LeadIQ: capture-to-CRM for SDR teams
LeadIQ is built around capturing a prospect from a profile and pushing it to your CRM. The free plan has 1 user and 50 credits. Pro uses a credit slider with five users included: 200 credits a month is $20 billed monthly or $15 billed annually, and the top slider tier (6,750 credits a month) is $290.25 a month on monthly billing. Credits cost 1 for an email, 10 for a phone and 11 for both, and every plan offers a 30-day trial.
LeadIQ says it holds 750M+ professional profiles, claims an 85% global mobile match rate and phone accuracy above 90%, and says every data supplier passes a GDPR and CCPA review. That last claim is worth asking about, because the supplier chain is exactly where data brokers get into trouble. Rollover isn't stated.
| Pros | Cons |
|---|---|
| Five users included in Pro | Phone is 10 credits |
| CRM capture workflow | Rollover not stated |
| 30-day trial | Credit slider makes cost per contact hard to compare |
Best for: SDR teams that want every capture to land in the CRM automatically.
9. Prospeo: low-cost verified emails and mobiles
Prospeo prices per user. Free is 100 credits a month; Starter is $49 monthly or $441 a year; Growth is $99 monthly or $888 a year; Pro is $249 monthly or $2,241 a year. Monthly plans carry 2,000, 5,000 and 15,000 credits, and yearly plans grant 24,000, 60,000 and 180,000 credits upfront. A verified email is 1 credit and a mobile is 10, and credits do not roll over. Add-ons start at 1,000 credits for $10.
Prospeo claims 300M+ profiles, 125M+ verified mobiles and 98% accuracy, with intent leads refreshed weekly and the full dataset roughly every 30 days. The pricing page carries a GDPR badge, but it isn't a substitute for a data processing agreement, so ask for one.
| Pros | Cons |
|---|---|
| Low entry price and a 100-credit free plan | No rollover |
| Verified results only | Mobile is 10 credits |
| Big annual credit grants | Per-user pricing |
Best for: small teams that want mobiles at a lower cost than the plan-based tools.
10. Findymail: you pay only for verified results
Findymail leads with a guarantee. It charges only for verified results and promises a bounce rate under 5%, refunding credits if it's exceeded. Plans: Individual at $99 a month with one seat, Team at $399 a month with five seats and Scale at $999 a month with 20 seats. A credit plan starts at $99 a month for 5,000 Finder and 5,000 Verifier credits. An email is 1 credit and a phone is 10, with rollover up to twice the monthly allowance. The yearly toggle advertises "2 months free", but no annual dollar figure is printed, so confirm it with sales. The free trial is 10 credits with no card.
Findymail lists SOC 2 Type 2, GDPR compliance and EU hosting. One limit matters if you sell globally: the mobile finder covers non-EU numbers only, which sidesteps one of the stricter regimes but narrows coverage. A CRM-cleaning add-on, Datacare, starts at $500 a month billed annually.
| Pros | Cons |
|---|---|
| Bounce guarantee with refund | No annual price shown |
| Pay only for verified results | Mobile finder excludes EU numbers |
| EU hosting | Highest entry price in the email-first group |
Best for: teams where a bounced email is expensive, such as new domains with fragile sender reputation.
11. Snov.io: flat plans with outreach built in
Snov.io sells flat accounts with unlimited seats. The trial is free and never expires: 50 credits and 100 recipients. Paid plans (monthly, then per month on annual billing at 25% off) are Starter at $39 or $29.25, Pro S at $99 or $74.25, Pro M at $189 or $141.75, Pro L at $369 or $276.75 and Ultra at $738 or $553.50, covering 1,000 to 100,000 credits. A credit equals one prospect, one email search or one verification, and unused credits expire after 30 days unless you're on annual billing or have renewal enabled.
Be careful with its database claims. One page says 500M+ verified contacts while the FAQ on the same page says over 50 million leads, so treat neither as reliable. Snov.io states a 98% accuracy rate for its email verifier, plus GDPR and CCPA coverage. LinkedIn automation slots are an extra $69 a month each, and that's the feature to evaluate carefully against LinkedIn's terms, covered below.
| Pros | Cons |
|---|---|
| Unlimited seats | Contradictory database size claims |
| Email finder, verifier and outreach in one tool | Unused credits expire after 30 days on monthly billing |
| Never-expiring free trial | LinkedIn automation slots cost extra |
Best for: teams that want finding, verifying and sending in one flat-priced tool.
12. Skrapp.io: low cost, email only
Skrapp.io is the budget email finder. Free is 50 credits for one user. Professional is $29 a month billed annually with 2,000 credits a month and two users, and Enterprise is $262 a month billed annually with 50,000 credits a month, 15 users, an API and SSO. The page shows 25% off on yearly billing.
The credit model is friendly: one credit per valid or catch-all email, with invalid and unknown results free, and paid plans roll credits over in a shared team pool. Skrapp.io claims 40M+ companies and 2M+ professionals as users. It links a GDPR page and data processing agreement. It doesn't publish phone numbers, so pair it with a phone tool if you dial.
| Pros | Cons |
|---|---|
| Invalid and unknown results are free | Email only |
| Rollover and shared credit pool | Two users on the entry paid plan |
| Low entry price | Small published company and contact claims |
Best for: a lean team that needs emails from LinkedIn at the lowest cost.
13. Hunter: the domain-first email finder
Hunter started as a domain search tool, and its extension now finds and verifies emails on profile pages. Plans are flat per account with unlimited users: Free at 50 credits a month; Starter at $49 monthly or $34 a month billed $408 a year with 2,000 credits; Growth at $149 monthly or $104 a month billed $1,248 a year with 10,000 credits; Scale at $299 monthly or $209 a month billed $2,508 a year with 25,000 credits. Finding an email is 1 credit and verifying is 0.5. Monthly credits reset with no rollover, and annual plans receive the whole year's credits upfront.
Hunter says it indexes 150M professional emails from 650M public sources, reports 7M+ users on its homepage, states GDPR and CCPA compliance and hosts in Belgium on Google Cloud. It does not find phone numbers, so it's not a full replacement for the tools above.
| Pros | Cons |
|---|---|
| Unlimited users on every plan | No phone numbers |
| Verification costs half a credit | Monthly credits don't roll over |
| EU hosting | Email only, no phone data |
Best for: email-only prospecting where you need unlimited teammates and a verifier.
14. Datanyze: a contact-reveal extension from the ZoomInfo family
Datanyze is now a contact-reveal Chrome extension, owned by ZoomInfo since 2018. Pricing is per user: Nyze Pro 1 is $29 a month billed monthly (80 credits) or $21 a month billed yearly (960 credits a year); Nyze Pro 2 is $55 monthly (160 credits) or $39 a month billed yearly (1,920 credits a year). Yearly plans are non-refundable. One credit reveals one contact.
The "free" plan is Nyze Lite, a 90-day trial with 10 credits a month that ends access afterward, so don't count it as a permanent tier. It's best for people already inside ZoomInfo's ecosystem. For the full platform picture, see the best ZoomInfo alternatives.
| Pros | Cons |
|---|---|
| Cheap per-user reveal pricing | Free tier is a 90-day trial |
| ZoomInfo ownership | Small monthly credit pools |
| Simple one-credit-per-contact model | Yearly plans are non-refundable |
Best for: individual reps who want a low-cost contact reveal and don't need a full database.
Free Tiers and Phone Credit Costs Compared
This is the table most buyers want and few vendors make easy. Phone cost is shown as the credit multiplier against an email where the vendor prints one.
| Tool | Free or trial allowance | Email credit | Phone credit |
|---|---|---|---|
| Lusha | 40 credits/mo, 1 user | 1 | 5 |
| Apollo.io | 900 credits per seat per year (75/mo) | 1 | 8 |
| ContactOut | 5 emails, 5 phones, 5 exports per day | Unlimited on paid (fair use) | Unlimited on Email and Phone plan (fair use) |
| SignalHire | 5 credits, or 10/mo with extension | 1 per contact | 1 per contact (separate plan) |
| RocketReach | 5 free lookups | 1 lookup | Included in Pro and Ultimate lookups |
| Kaspr | 15 B2B email, 5 phone, 5 direct email per month | Unlimited B2B (capped) | Allowance per plan, add-ons from EUR 0.35 |
| Cognism | Demo and data sample, no free plan | 1 per contact | 1 per contact |
| LeadIQ | 50 credits, 1 user | 1 | 10 |
| Prospeo | 100 credits/mo | 1 | 10 |
| Findymail | 10 credits | 1 | 10 |
| Snov.io | 50 credits, never expires | 1 | No phone credit listed |
| Skrapp.io | 50 credits, 1 user | 1 | No phone credit listed |
| Hunter | 50 credits/mo | 1 | No phone credit listed |
| Datanyze | 10 credits/mo for 90 days | 1 per contact | 1 per contact |
The phone column tells the story. Where the vendor meters phones separately, the multiplier is 5x to 10x an email. Where it bundles them into a single contact credit, the plan price is higher. Neither is better, but you should compare cost per phone number you'll actually use, not per credit.
Monthly vs Annual Headline Pricing
Annual billing is cheaper than monthly in every row here, but the rules differ. Quote the billing term whenever you compare.
| Tool | Monthly billing | Annual billing |
|---|---|---|
| Lusha Starter | $49.90/mo | $37.45/mo ($449.10/yr) |
| Apollo Basic (per seat) | $65/mo | $49/mo |
| ContactOut Email | $49/mo | $468/yr |
| SignalHire email (600 credits/mo, 7,200 credits/yr) | $49/mo | $469/yr |
| RocketReach Essentials | $49/mo | $399/yr (US list) |
| Kaspr Starter (per user) | EUR 59/mo | EUR 45/mo |
| LeadIQ Pro (200 credits/mo) | $20/mo | $15/mo |
| Prospeo Starter | $49/mo | $441/yr |
| Findymail Individual | $99/mo | Annual discount available, no figure printed |
| Snov.io Starter | $39/mo | $29.25/mo |
| Skrapp.io Professional | Not shown on the pricing page | $29/mo billed annually |
| Hunter Starter | $49/mo | $34/mo billed $408/yr |
| Datanyze Pro 1 | $29/mo | $21/mo billed yearly |
| Cognism | Pricing on request | Pricing on request |
Accuracy: What Vendors Claim and What to Test
Every vendor in this list publishes a number or avoids publishing one. The table lists exactly what's stated, attributed to the vendor.
| Tool | Stated accuracy or data claim | Source |
|---|---|---|
| Lusha | 98% email, 85% US and 86% global phone | lusha.com |
| Apollo.io | 98% email accuracy, 240M+ contacts | apollo.io |
| ContactOut | 99% accuracy, "triple verified" | contactout.com |
| RocketReach | 98% accuracy, 700M professionals | rocketreach.co |
| LeadIQ | 85% global mobile match, phone accuracy above 90% | leadiq.com |
| Prospeo | 98% accuracy, 125M+ verified mobiles | prospeo.io |
| Findymail | Bounce rate under 5%, with refund | findymail.com |
| Snov.io | 98% accuracy on the email verifier | snov.io |
| SignalHire, Kaspr, Hunter, Skrapp.io | No accuracy percentage published | Vendor pages |
Several vendors claim 98% and ContactOut claims 99%, which means the number doesn't separate them. A sharper test is what happens when a result is wrong. SignalHire and RocketReach charge only on a hit, Findymail refunds credits above a 5% bounce rate and Skrapp.io makes invalid results free. Those policies tell you more than a headline percentage. The Gmail sender rules explain why: senders of more than 5,000 messages a day must keep spam rates below 0.30%, so a list full of dead addresses can put the sending domain you rely on at risk.
Run a blind test before you buy. Pull 100 profiles from your own ICP, reveal them in two or three tools and check each address with a separate verifier. Pay attention to the share of results that are catch-all or role-based. Our lead data enrichment guide explains how to build a verification step into the workflow, and the lead data management library page covers how long to keep revealed data.
Credit Models: Four Ways You'll Get Charged
| Model | How it works | Tools |
|---|---|---|
| Per-contact credit, plan seats bundled | One flat price, a credit pool, seats included | Lusha, SignalHire, Snov.io, Hunter, LeadIQ |
| Per-seat subscription with pooled credits | Price grows with headcount, credits shared | Apollo.io, RocketReach, Kaspr, Prospeo, Datanyze |
| "Unlimited" with a fair-use ceiling | Marketed as unlimited, capped in the terms | ContactOut, SignalHire, RocketReach, Kaspr |
| Quote-based credit bundle | Platform fee plus seat credits | Cognism |
Three habits keep the meter honest. Read the terms behind every "unlimited" badge, because the caps are real: 2,000 email and 1,000 phone credits at ContactOut, 10,000 lookups a month at RocketReach and 10,000 credits at Kaspr. Check whether credits roll over, since Lusha's monthly plans, Kaspr's paid plans, Skrapp.io and Findymail do and Apollo.io and Prospeo don't. And ask whether CRM pushes, bulk exports and API calls cost extra: at RocketReach, they consume exports rather than lookups.
Compliance: LinkedIn's Terms, GDPR, CCPA and Phone Consent
This is the section most roundups skip, and it's where the real risk sits. It's information to take to your counsel, not legal advice.
LinkedIn's own rules
LinkedIn's User Agreement lists what members must not do. Among the restrictions in section 8.2, members may not "develop, support or use software, devices, scripts, robots or any other means or processes (such as crawlers, browser plugins and add-ons or any other technology) to scrape or copy the Services, including profiles and other data from the Services." It also prohibits copying, using, displaying or distributing information obtained from the Services "whether directly or through third parties (such as search tools or data aggregators or brokers)" without the content owner's consent, and using bots or other unauthorized automated methods to access the Services or download contacts. It bars overlaying or modifying the Services too.
| Clause topic | What the User Agreement says, in short | Why it matters for extensions |
|---|---|---|
| Scraping and add-ons | No software, scripts, robots, crawlers, browser plugins or add-ons to scrape or copy the Services | Extensions that read profile pages sit close to this line |
| Third-party data | No copying or using information from the Services via data aggregators or brokers without consent | Applies to downstream use of exported data |
| Automation | No bots or unauthorized automated methods to access the Services or add or download contacts | Bulk "auto-connect" or auto-export features carry the most account risk |
| Modifying the Services | No overlaying or modifying the Services or their appearance | Sidebars that insert elements into LinkedIn |
What does this mean in practice? The agreement is a contract between you and LinkedIn, and the clearest consequence is for your account: LinkedIn can restrict or end accounts that break it. But "a vendor sells it" isn't "LinkedIn allows it", so don't run automated, high-volume extraction from a profile you can't afford to lose. Our prospecting strategy page covers building a mix of sources so one platform doesn't carry the whole pipeline.
GDPR: the Kaspr decision
The clearest enforcement example is the Kaspr case. The EDPB's summary says Kaspr markets a Chrome extension that lets paying customers get the professional contact details of people whose LinkedIn profiles they visit, from a database of about 160 million contacts. CNIL received many complaints from people who had been canvassed. It found breaches of the obligation to have a legal basis (Article 6), to set a proportionate retention period (Article 5), to inform people (Articles 12 and 14) and to respect the right of access (Article 15). It fined Kaspr EUR 240,000 and ordered it to stop collecting data of people who chose to limit the visibility of their contact details and to delete data collected that way.
The lesson is not "avoid Kaspr". It's that the vendor's legal basis for its database becomes a question about your outreach too. Before buying any tool here, ask four things: what the lawful basis is, how people are notified, how long records are kept and how someone's objection or access request is handled. Those match the articles CNIL cited.
CCPA and PDPA
California's CCPA gives residents rights to know, delete and opt out of the sale or sharing of personal information, and data brokers have their own registration duties. Cognism says it's a registered California data broker, which is the kind of registration to ask any vendor about. In Southeast Asia, Singapore's PDPA governs how organisations collect, use and disclose personal data, and neighbours such as Malaysia and Indonesia run their own regimes. Ask each vendor which regions its data covers and whether it can exclude yours. ContactOut's option to exclude US and UK data and Findymail's non-EU mobile coverage are examples of region controls.
Phone consent: TCPA, DNC, TPS and CTPS
Phone numbers are where fines get large. In the US, the FTC says violations of the Telemarketing Sales Rule carry civil penalties of up to $53,088 for each violation, and telemarketers must synchronize their lists every 31 days. The same page says the national registry rule doesn't apply to business-to-business calls, so a cold call to a work number isn't treated the same as a call to a consumer, but check state rules and which number you've revealed (a mobile phone may be personal). Under the TCPA, a person can recover actual loss or $500 in damages for each violation, whichever is greater, and courts can treble it for willful violations.
In the UK, the TPS and its corporate counterpart CTPS cover businesses as well as consumers. In May 2026 the ICO fined Energy Prices Direct £160,000 for over 700,000 unsolicited marketing calls to TPS and CTPS numbers, including businesses.
| Rule | Where | What it covers | Stated penalty |
|---|---|---|---|
| FTC Telemarketing Sales Rule and Do Not Call | US | Telemarketing calls, list sync every 31 days | Up to $53,088 per violation |
| TCPA private action | US | Individuals suing for violations | $500 per violation, trebled if willful |
| TPS and CTPS | UK | Consumer and corporate numbers | £160,000 ICO fine in one 2026 case |
| GDPR | EU | Lawful basis, transparency, access | EUR 240,000 Kaspr fine |

Pre-Purchase Compliance Checklist
| Question to ask | Why it matters |
|---|---|
| What is the lawful basis for your database? | The core issue in the Kaspr decision |
| Can you exclude data for my regions? | PDPA, GDPR and CCPA differ by region |
| Do you screen phones against TPS, CTPS and DNC? | Phone fines are the largest exposure |
| How long do you keep a record, and how do objections work? | Retention and access were breached in the CNIL case |
| Can I get a DPA and a sub-processor list? | Needed by any compliance review |
| What happens to credits when a result is wrong? | Refund and bounce policies differ widely |
What to Do Next
Pick two tools from your persona row, run a two-week test on the same 100 profiles and check every email with a separate verifier. Track hit rate, bounce rate and credits per usable contact, then ask each vendor the six checklist questions above in writing. The cheapest tool is rarely the one with the lowest cost per good contact. For the next layer of the stack, read the best email finder tools, the best data enrichment tools and the best B2B data providers, or return to the sales intelligence hub.
