How to Choose Email Marketing Software for Nonprofits
Turn this article into takeaways for your work.
Each assistant summarizes the article only for you and suggests best practices for your work.
Updated September 2026.
For most nonprofits under roughly 10,000 constituents, the right answer is a general email platform running beside the donor database at the nonprofit rate, not a second system that duplicates donor records. The question was never which tool has better templates. It's where the giving history lives, who has to retype it, and what happens to that arrangement in the four weeks of December when everything gets sent at once.
So this guide starts with whether you need to buy anything separate at all, since a growing number of donor platforms bundle email at zero marginal cost. From there: which discounts and free programs are real, what the shortlist costs at three list sizes, and how to email a donor file that has been sitting untouched. How to choose email marketing software covers the general-purpose version of this decision.
Do you need to buy a separate email tool at all?
For a decent share of readers the most useful outcome here is deciding not to buy. Email is bundled into enough fundraising platforms now that a separate subscription is often a second bill for something you already own, plus a sync chore nobody volunteered for.
| Your situation | What you need instead | Why buying is premature |
|---|---|---|
| Under about 500 constituents, one appeal a quarter | A free tier, or your donor platform's built-in sender | A paid plan buys features you won't open |
| Already on Givebutter, Zeffy, Bloomerang, or Neon CRM | The email tool in the platform you already pay for | You'd pay twice, then maintain a sync between two lists |
| Donor records still live in a spreadsheet | Fix the database first, see choosing a nonprofit CRM | An email tool fed from a spreadsheet inherits every duplicate |
| A volunteer sends everything from a personal Gmail account | Domain authentication first, covered below | Software won't fix a reputation problem it didn't cause |
| 2,000+ constituents, segmented appeals, a real year-end campaign | A dedicated platform, chosen with this guide | The profile the category is priced and built for |
Land in that bottom row and keep reading. Land anywhere else and the narrower fix gets you there faster, for less.
Key Facts:
- Nonprofits raised an average of $2.40 in email-sourced revenue per subscriber in 2025, up from $1.87 the year before, and email revenue rose 16% on average, per the M+R Benchmarks 2026 study, which analyzed 2025 data from 180 nonprofits.
- Email accounted for 11% of all online revenue in 2025, and nonprofits received $54 for every 1,000 fundraising emails sent, a 4% year-over-year increase, per that same M+R Benchmarks 2026 study.
- Dollars raised grew an estimated 4.3% year over year in Q1 2026 while donor counts fell an estimated 0.8%, per the Fundraising Effectiveness Project's Q1 2026 report from AFP and GivingTuesday, published July 2026. More money from fewer people is a retention problem, and retention is an email problem.
- Nonprofit lists average 4,191 contacts with a 28.59% open rate and a 3.29% click rate, per Neon One's The Nonprofit Email Report, which evaluated 37,472 campaigns sent in 2022 and remains its most recent edition (Neon One benchmarks).
The fork that actually decides this
Commercial email guides assume customer data sits in an ecommerce store, so they rank tools by Shopify integration depth. Nonprofit data doesn't work that way. Giving history, soft credits, pledge schedules, and household links live in a donor database, and the real question is whether email reaches into that database or keeps its own copy of everyone.
| Architecture | How it works | What it costs you |
|---|---|---|
| General email tool beside a donor CRM | Mailchimp, Brevo, MailerLite, or Constant Contact syncs contacts and a few fields from Bloomerang, Neon CRM, Salesforce NPSP, or DonorPerfect | Two systems, one sync, and a standing argument about which is authoritative |
| All-in-one fundraising platform with email built in | Givebutter, Zeffy, Bloomerang, and Neon CRM all send from the same record that holds the gift | Email features usually run a generation behind the dedicated tools |
| Donor database plus a full marketing platform | Salesforce NPSP or similar, wired to marketing automation | Real implementation cost, and it stops working the week that admin leaves |
Most organizations under 10,000 constituents do better in row two than they expect. The pitch for row one is better segmentation and automation, which is real, but only if someone on staff will actually build the segments. Marketing automation vs CRM untangles the same overlap commercially and the logic transfers.
What nonprofit email has to do that generic tools don't
Every platform here sends a newsletter. The gap shows up in five jobs commercial email tools were never designed around.
| The job | What it needs | Where generic tools fall down |
|---|---|---|
| Appeals segmented by giving history | Segmentation on last gift date, lifetime giving, and gift count | Email tools store a contact and a tag, not a giving history, so segments go stale between syncs |
| Recurring-gift receipts and renewals | Transactional sending off the payment event, with tax-receipt language | Marketing tools treat receipts as another campaign, a compliance and deliverability mistake at once |
| Lapsed-donor re-engagement | A trigger on "no gift in N months," not "no email opened in N months" | Automation fires on clicks, not giving behavior, the metric that matters |
| Board and funder reporting | Per-appeal revenue attribution you can paste into a board deck | Open rates don't answer "what did the spring appeal raise," the only question the board asks |
| Household deduplication and soft credits | Recognition that two addresses can be one giving household | Generic tools count contacts, so a couple gets two appeals and one thank-you |
If four of those rows are load-bearing, bundled email inside a donor platform usually wins even when its editor is uglier. If one or two matter, a dedicated tool with a decent sync feels better daily.
What to look for: evaluation criteria
Score finalists on these before the demo, not during it.
| Criterion | What to check | Why it matters |
|---|---|---|
| Donor database integration | Native and bi-directional, or a one-way CSV export somebody runs by hand | A manual export is the chore that gets skipped in December, when it matters most |
| Which fields actually sync | Last gift date, lifetime giving, recurring status, fund designation, not just name and email | Segmentation is capped by the fields that make it across |
| Segmentation on giving data | Whether "gave in 2024, not 2025, over $250 lifetime" is buildable without exporting | That one segment drives most of a year-end appeal's revenue |
| Domain authentication | SPF, DKIM, and DMARC support, and whether the platform signs with your domain | The most common nonprofit deliverability failure, covered below |
| Daily send caps | The per-day cap, not just the monthly total | A 4,000-person appeal against a 300-per-day cap takes two weeks to land |
| Export on the way out | Whether you leave with your list, history, and unsubscribes intact | Losing the unsubscribe list on migration is a legal problem, not an inconvenience |
The email marketing evaluation criteria checklist turns these into a scored comparison, and how to build a software shortlist covers reaching two finalists fast.
Nonprofit discounts and free programs
Nearly every major email vendor publishes a nonprofit rate. They are not equivalent, and two have a timing rule that costs money if you miss it.
| Vendor | Published nonprofit program | Mechanics |
|---|---|---|
| MailerLite | 30% off any paid plan | A separate sponsorship also gives selected learning and arts nonprofits a free Power plan for two years, by nomination rather than application |
| Constant Contact | 20% off prepaying six months, 30% off prepaying 12 months | Tied to prepayment, so the 30% rate needs a year of cash up front |
| ActiveCampaign | 20% off on proof of nonprofit status | Requested by emailing sales or support, not self-serve |
| Brevo | 20% off paid plans for eligible organizations | A coupon issued after support verifies registration |
| Mailchimp | 15% for verified nonprofits and charities | Request before you buy. Mailchimp states it cannot apply discounts retroactively |
| Klaviyo | No published nonprofit program found | Built around ecommerce profiles and revenue attribution, a poor fit for donor data |
Two rules follow. Apply before you subscribe, because at least one vendor refuses to backdate. And read the percentage against the list price: 15% off a contact-metered plan that doubles at 5,000 contacts is worth less than 20% off a plan metered on emails sent.
The genuinely free options sit in a different column, because donors fund them rather than you. Zeffy charges $0 with no platform, transaction, or card fee, and includes donation forms, a CRM, and newsletter email; it states about two in three donors add an optional tip at checkout. Givebutter runs the same model: 0% platform and 0% processing when tips are on, which it says 92% of donors cover, and with tips off a flat 3% platform fee plus 2.9% + 30 cents per card gift or 1.9% + 30 cents per ACH gift.
You aren't paying nothing there, you're asking donors to pay, which most of them do. Whether that works depends on your donor base and how your board feels about a tip prompt on a giving form. Free vs paid software: when to upgrade has a framework for the call.
Key questions before you commit
- Which fields sync from our donor database, and how often? Ask for the field list in writing. "Full integration" usually means name, email, and tags.
- What is the daily send cap on this plan? Divide your list by it. More than two days and your appeal has a delivery schedule instead of a send date.
- Can we build a lapsed-donor segment on gift date without exporting? Have them build it live against a sample file, not a slide.
- Does the nonprofit discount stack with annual billing, and can it be applied after we subscribe? Get both answers before you enter a card.
- What happens to our unsubscribe list if we leave, and who signs the mail? The list has to come with you in full. And if the platform won't let you authenticate your own domain, walk.
The shortlist at a glance
Grouped by architecture, not ranked. Figures are the vendors' own published prices before any nonprofit discount.
General email platforms that sit beside a donor database:
| Tool | Best for | Free tier | Entry paid price |
|---|---|---|---|
| MailerLite | Best published nonprofit rate, clean editor | 250 subscribers, 2,500 emails/month, 2 seats | Comfort $12/month billed monthly, annual saves 10%; Power $25/month |
| Brevo | Large lists mailed infrequently | 300 emails/day, up to 100,000 contacts stored, 1 user | Starter $9/month billed monthly or $8.08/month billed annually, from 5,000 emails/month; Standard $18 monthly, $16.17 annual |
| Mailchimp | The broadest integration ecosystem | 250 contacts, 500 sends/month, 250/day cap, 1 seat, 1 audience | Essentials $13/month, Standard $20/month, Premium $350/month, all at the 0 to 500 contact tier, billed monthly |
| Constant Contact | Orgs running in-person events | No free plan, trial only | Lite $12/month billed monthly or $10.20/month billed annually; Standard $35 or $29.75; Premium $80 or $68 |
| ActiveCampaign | Real automation logic on giving behavior | No free plan, 14-day trial | Starter $15/month, Plus $49/month, Pro $79/month, Enterprise $145/month, all at 1,000 contacts, billed annually |
Fundraising platforms with email built in:
| Tool | Entry price |
|---|---|
| Zeffy | $0, funded by optional donor tips. The trade is a tip prompt on your giving forms |
| Givebutter | Free core platform. Givebutter Plus, adding the advanced email editor, texting, and automations: $29/month at 250 contacts or fewer, $79/month at 1,000, $129/month at 2,500 |
| Bloomerang | CRM from $125/month billed annually; the all-in-one Giving Platform from $242/month billed annually, priced on record count with unlimited users |
| Neon CRM | From $99/month, quoted after a demo, priced on total revenue rather than record count, with unlimited contacts and sends. Memberships add 10% of CRM cost, events 20%, volunteers 10% |
What it costs at 2,000, 10,000 and 50,000 contacts
Only some of these vendors give you a number without a calculator or a call. What all of them publish is the metering unit, and the unit predicts your bill's shape better than any entry price.
| Vendor | Billed on | Published entry figure and its tier | As the file grows |
|---|---|---|---|
| Brevo | Emails sent per month | Starter $9/month billed monthly, $8.08/month billed annually, from 5,000 emails/month | Flat against list growth. A 50,000-name file mailed quarterly costs less than a 5,000-name file mailed weekly |
| MailerLite | Active subscribers | Comfort $12/month billed monthly, at the entry subscriber tier | Steps up by subscriber bracket on the vendor's calculator |
| Mailchimp | Contacts | Essentials $13/month and Standard $20/month, at the 0 to 500 contact tier, billed monthly | Steps up by contact bracket, and the gap to a five-figure list can reprice the decision |
| Constant Contact | Contacts, with a send cap scaled to the tier | Lite $12/month monthly, $10.20/month billed annually, at the entry contact tier | Steps up by bracket, and the send cap moves with it |
| ActiveCampaign | Contacts, by a per-tier multiplier | Starter $15/month and Plus $49/month, both at 1,000 contacts, billed annually | The 1,000-contact figure is not the figure at 10,000 |
| Neon CRM | The organization's total revenue | From $99/month | Unlimited contacts and sends, so list size isn't the variable |
Three readings. At 2,000 contacts you're past every general-platform free tier except Brevo's, and while Brevo's free plan holds the contacts easily, its 300-per-day cap turns one appeal into a seven-day rolling send. At 10,000 contacts the contact-metered tools have climbed several brackets above their headline price while a send-metered plan has barely moved, which is why orgs mailing a big file four times a year keep landing on Brevo. At 50,000 contacts you're running a donor database anyway, so the real comparison is a Neon CRM or Bloomerang quote against a contact-metered subscription plus its integration.
Two costs sit outside every rate above: staff time to build segments, and the migration. The software total cost of ownership guide covers both.
Deliverability and list hygiene on an old donor file
This is where nonprofit email differs most from the commercial version, and where the first send after a migration goes wrong. A donor file is old by design: it holds people who gave once in 2019 and were never removed, because removing a donor feels like giving up on them.
M+R's 2026 study puts numbers on the attrition. Across participants in 2025, 4% of subscribers became unreachable through bounces and a further 12% were lost to unsubscribes. Yet only 34% of nonprofits delete unengaged subscribers regularly, per the 2026 Nonprofit Tech for Good Report compiled in Nonprofit Tech for Good's email statistics. A file that's never pruned is the file most likely to get a whole organization filtered.
| The problem | What to do |
|---|---|
| A volunteer sends appeals from a personal account, so mail claiming your domain fails DMARC alignment | Authenticate the org domain and route every sender through it, no exception for the board chair |
| Missing SPF, DKIM, or DMARC records | Google's sender guidelines require SPF and DKIM of all senders, add DMARC above 5,000 messages a day to Gmail, and require spam rates under 0.3%. Set all three up before the first send |
| A three-year-old list mailed cold, spiking hard bounces on send one | Mail the most recent 20% first, confirm bounce rates are sane, then widen in stages |
| Lapsed donors who never unsubscribed, dragging placement for people who care | One re-engagement send, then suppress non-openers rather than deleting the record |
| Receipts sent through the marketing stream, where a promotions filter catches them | Send receipts transactionally, off the payment event, never as a campaign |
The hygiene point people resist: suppressing a lapsed donor from email doesn't delete them from the donor database. Two records, and only one should be pruned aggressively.
The appeal calendar, and surviving year-end
Nonprofit sending isn't evenly distributed. It clusters hard in the last six weeks of the year, and a plan that's comfortable in June can hit a send cap on 30 December.
| Period | What it demands from the tool |
|---|---|
| Spring appeal | Segmentation on last gift date, plus daily headroom to reach the file in one day |
| Summer stewardship | Cheap sending on newsletters and program updates, when send-metered plans look best |
| Fall campaign and events | Small fast sends to subsets, with registration data flowing back to the record |
| GivingTuesday to 31 December | Daily caps that clear the whole list, and receipts that never queue behind a campaign |
| January | Transactional volume for thank-yous, tax summaries, and renewals |
Cost the platform against December, not June. A daily cap you never notice for eleven months is what puts a 31 December appeal in inboxes on 2 January.
How to choose: a decision framework
Match your profile to a direction rather than a brand.
| Your profile | Direction | Why |
|---|---|---|
| Under 500 constituents, volunteer-run, no budget | Zeffy, or your donor platform's built-in email | Zero cost, one contact record, nothing to sync |
| Online and peer-to-peer fundraising is the core motion | Givebutter free, adding Plus when you need automations | CRM and email come with tools you were buying anyway |
| 2,000 to 10,000 constituents, a real database, one staff owner | MailerLite at the 30% nonprofit rate | The best published discount here, on a tool one person can run |
| Large file, low send frequency, a few big appeals a year | Brevo | Send-metered billing means list growth doesn't reprice you |
| You run in-person events and want them in one product | Constant Contact, prepaid 12 months for the 30% rate | Event tooling plus the deepest prepayment discount here |
| You want journeys triggered by giving behavior | ActiveCampaign at the 20% nonprofit rate | The only automation here that branches on donor behavior |
| Memberships, events, or volunteers all need one record | Neon CRM, or Bloomerang if retention reporting leads | Unlimited email in the database beats maintaining a sync |
| Nobody on staff will build segments, honestly | Whatever your donor platform already includes | An unused segmentation engine is a subscription, not a capability |

Frequently asked questions
Should our email tool live inside our donor database or next to it?
Inside, unless a specific capability you'll genuinely use is missing. One contact record removes a whole class of problem: stale segments, duplicate appeals to the same household, the monthly export nobody remembers to run. Move to a separate tool when segmentation on giving history or behavior-triggered automation becomes the bottleneck.
Which nonprofit discounts are actually worth applying for?
MailerLite's 30% off any paid plan is the largest published percentage here, and Constant Contact matches it at 30% if you prepay 12 months. ActiveCampaign and Brevo each publish 20%, Mailchimp 15%. Mechanics matter more than percentage: request the discount before you first subscribe, since Mailchimp states it cannot apply discounts retroactively.
Can a small nonprofit run its whole email program for free?
Yes, and it's a reasonable starting point. Zeffy charges nothing at all and includes donation forms, a CRM, and newsletter email, funded by optional donor tips. Givebutter's free plan works the same way. Among general tools, MailerLite's free tier covers 250 subscribers and 2,500 emails a month, and Brevo's covers 300 emails a day against up to 100,000 stored contacts, generous on list size and tight on daily volume.
How do we email a donor file we haven't touched in three years?
In stages. Send to the most recently active 20% first, check the bounce rate, then widen. A cold blast to a stale file spikes hard bounces and damages sender reputation for everything afterward, gift receipts included. Run one re-engagement message to the non-responders, then suppress them from marketing sends while keeping them in the donor database.
Do we need a separate tool for year-end appeals?
No, but check that your normal plan survives December. Look at the daily send cap rather than the monthly total, and divide your list by it. If a full-file appeal takes more than a day to deliver, upgrade the tier before GivingTuesday or schedule the send as a rollout.
Making the call
Start by checking what you already own. If a donor platform in your stack sends email, use it until a specific limitation costs you money. When that limitation arrives it's almost always segmentation on giving history or automation on donor behavior, and that tells you which tier to shop.
When you do buy, price it against December and apply the nonprofit discount before you enter a card. Then spend the first month on the boring part: authenticate your domain, warm the list, build the lapsed-donor segment. That work turns the tool into revenue. The subscription alone doesn't.
