The short answer: apply the nonprofit discount before comparing prices, because it reshuffles the whole ranking. GetResponse wins on value — its 50% nonprofit discount is the largest in the category, cutting Starter to about $9.50/month for 1,000 contacts. MailerLite is the cheapest to run overall (≈$8.40/month after its 30% nonprofit discount at the entry tier). Constant Contact is the pick if events and fundraisers are central, with built-in event registration and ticketing. Mailchimp only makes sense if you have dedicated staff to use its automation depth, and Brevo is the best free start — 300 emails/day with unlimited contacts, plus transactional receipts in the same account.

What nonprofit email actually needs (that generic email marketing doesn’t)
A business sends email to move a customer toward a purchase. A nonprofit sends email to move a supporter toward a relationship — and the purchase, the donation, is one step inside it. That changes the software requirements at a mechanical level, in six ways.
1. The donor lifecycle is a journey, not a campaign. A donor’s path runs supporter → first gift → second gift → recurring donor → lapsed donor → reactivated. The critical hinge is the second gift: fundraising data consistently shows the first-to-second-gift step is the leakiest in the whole funnel. That means your platform needs automation that triggers on donation events — “first gift received → thank-you → impact story at day 7 → second-gift ask at day 30” — not just a calendar of broadcasts. Evaluate platforms on their donation-event triggers and journey builders first.
2. The ask must scale to the donor’s history. This is RFM logic applied to giving: recency, frequency, and monetary value of past gifts should set the ask amount. A $25 donor asked for $35 gives; a $25 donor asked for $500 closes the email. The mechanism is segmentation on giving data — either synced from your donation platform or tagged manually — feeding dynamic ask amounts. If the platform can’t segment by gift history, your appeals are guessing.
3. Stewardship must outnumber solicitation. Lists that only ask burn out; donors who only hear from you when you want money stop opening. The emails that ask for nothing — impact stories, program updates, volunteer spotlights — are what keep the list warm between campaigns. Your platform needs to make the cultivation emails easy too: good templates, simple segmentation, and reporting that shows engagement beyond donation-attributed revenue.
4. Donation receipts are a separate email type. Every gift needs an immediate receipt — in the US it’s also tax documentation for the donor. Receipts are transactional email, and platforms price it differently: Brevo bundles it in the same account, Mailchimp charges $20 per 25,000-email block (paid plans only), MailerLite sells a separate Transactional plan, GetResponse reserves it for enterprise tiers. Before buying, decide whether receipts come from your email platform or from your donation tool — don’t pay for two pipes.
5. Events and volunteers are email workflows. Galas, fundraisers, volunteer shifts, and peer-to-peer campaigns run on invitations, RSVP tracking, and reminders. Constant Contact builds event registration and ticketing into the platform itself; everywhere else, you’re integrating with an event tool. If events are a major fundraising channel, that integration cost is part of the price comparison.
6. The nonprofit discount changes the ranking. Headline prices are misleading. GetResponse at $19/month looks mid-priced until the 50% nonprofit discount makes it $9.50 — suddenly it’s the cheapest real platform on this list. Always compare effective prices after the discount, and apply for the discount before purchasing: Mailchimp will not backdate it. Also watch the billing axis: platforms that bill on contacts punish list growth, and nonprofits’ lists grow with every campaign. Mailchimp counts unsubscribed and non-subscribed contacts toward your tier — years of unsubscribes silently inflating your bill is a real nonprofit trap, because churned supporters are exactly what a mission-driven list accumulates.
The platforms, product by product
All pricing below was researched on 2026-10-16 from vendor pricing pages and current third-party trackers; plans and discount terms change, so confirm on the vendor’s page before buying. Effective prices assume you complete nonprofit verification first.
GetResponse — best overall value (50% nonprofit discount)
GetResponse offers the largest nonprofit discount in the category: 50% off plans for charities and NGOs, confirmed on its own site. That turns the $19/month Starter (up to 1,000 contacts, unlimited sends) into about $9.50/month — the lowest effective price of any full-featured platform here. Annual billing adds another 18% off the base, though whether the nonprofit discount stacks with annual pricing isn’t published — confirm during signup, and ask about any logo-placement terms.
What the money buys: a real automation builder with donation-event triggers, landing pages, webinars (useful for donor education sessions and virtual fundraisers), live chat for your site, and integrations with major donation platforms via native connectors and Zapier. GetResponse also writes specifically for the nonprofit use case, with templates and guides aimed at charities.
Trade-offs: Starter includes only one automation workflow, so you may need the Marketer tier (from $59/month, ≈$29.50 after discount) for multi-journey donor programs. Transactional email for receipts is reserved for enterprise tiers, so plan to send receipts from your donation platform. Downgrades require contacting support rather than self-serve.
Best for: Nonprofits that want real donor-journey automation at the lowest effective price.
MailerLite — cheapest to run day to day
MailerLite gives verified nonprofits 30% off paid plans (it doesn’t combine with the 10% annual discount, so take whichever is bigger — it’s the nonprofit one). Comfort starts at $12/month for 500 subscribers, so the effective price is about $8.40/month; Power starts at $25/month (effective ≈$17.50). The free plan covers 250 subscribers and 2,500 emails/month — fine for a brand-new organization, not a home for a real list.
The case for MailerLite is operational: it’s the easiest editor of any platform here, automation and segmentation are included (not gated to premium tiers), and it doesn’t charge for unsubscribed contacts — the trap that inflates Mailchimp bills doesn’t exist. Deliverability is consistently strong in independent testing. It also integrates with donation platforms, and its digital-products tooling suits nonprofits that sell merchandise or course-style content.
Trade-offs: no built-in event registration/ticketing, no SMS in the standard plans, and transactional email is a separate Transactional plan. The free tier shrank to 250 subscribers in the 2025–2026 pricing overhaul, so treat it as a trial.
Best for: Small teams and volunteer-run communications where ease of use and the lowest monthly bill both matter.
Constant Contact — best for events and fundraisers
Constant Contact is the events specialist: built-in event registration and ticketing means one less subscription (no separate Eventbrite bill), with invitations, RSVP tracking, and reminders all in the same account. It also ships 600+ templates including nonprofit-specific designs, and phone, chat, and email support on every plan — a genuine advantage for volunteer-staffed teams.
The nonprofit discount is 30% off with 12-month prepay or 20% off with 6-month prepay on Standard and Premium plans, verified through TechSoup. Pricing: Lite from $12/month (not eligible for the discount), Standard from $35/month (effective ≈$24.50 with the 30% annual prepay), Premium from $80/month. There is no free plan — trial only.
Trade-offs: it’s the priciest effective option here, the discount requires committing to months of prepay, and real automation workflows live on the Premium tier. Send caps are tied to contact count with overage fees, so model your sending volume before the annual commitment.
Best for: Nonprofits where galas, fundraisers, and community events are a core fundraising channel.
Mailchimp — the one everyone asks about (honest take)
Mailchimp is the most recognized name in email, and its automation and segmentation depth is real — multi-step donor journeys, predictive analytics, and hundreds of integrations. If you have a dedicated communications person who will use that depth, it’s capable software.
But the nonprofit economics are the weakest here. The 15% nonprofit discount is the lowest of any major platform, applied through TechSoup verification, and it can’t be backdated — request it before buying. The free plan was cut to 250 contacts and 500 emails/month in 2026, which covers almost no real organization. Essentials starts at $13/month (500 contacts), Standard at $20/month (500). And the billing trap is real: Mailchimp counts unsubscribed and non-subscribed contacts toward your tier, so a list with years of churned supporters bills higher than its active size. Its own pricing pages don’t surface this; the bill does.
Best for: Larger nonprofits with dedicated comms staff running genuinely complex automation — everyone else should compare the effective prices above first.
Brevo — best free start, with receipts built in
Brevo (formerly Sendinblue) is the odd one out: no public nonprofit discount, but a free plan generous enough that many small nonprofits never need one — 300 emails/day with unlimited stored contacts. Starter is $9/month (5,000 emails), Standard $18/month (adds automation and A/B testing).
The structural advantage is that Brevo bundles three things in one account: marketing email, transactional email (donation receipts, no separate pipe or $20 blocks), and SMS/WhatsApp campaigns, plus a basic CRM. For a nonprofit that wants receipts, campaigns, and donor records under one bill, that consolidation is real. The catch: the free plan’s daily send cap means a big list mails over several days, and send-based billing rewards infrequent sending — a weekly newsletter to a large list costs more than you’d guess.
Best for: Starting at $0 with a long list you mail infrequently, and any nonprofit that wants donation receipts from the same platform as its campaigns.
Comparison table (researched 2026-10-16)
Prices below are entry paid tiers; “effective” means after the nonprofit discount is applied. All discounts require verification (typically TechSoup or charity registration).
| GetResponse | MailerLite | Constant Contact | Mailchimp | Brevo | |
|---|---|---|---|---|---|
| Entry paid price | $19/mo (1,000 contacts) | $12/mo (500 subs) | Standard $35/mo | Essentials $13/mo (500 contacts) | $9/mo (5,000 emails) |
| Nonprofit discount | 50% | 30% | 20–30% (prepay) | 15% | None |
| Effective entry price | ≈$9.50/mo | ≈$8.40/mo | ≈$24.50/mo (30% annual prepay) | ≈$11.05/mo | $9/mo |
| Free plan | Yes (limited) | 250 subs, 2,500 emails/mo | Trial only | 250 contacts, 500 emails/mo | 300 emails/day, unlimited contacts |
| Event ticketing built in | No | No | Yes | No | No |
| Transactional receipts | Enterprise tiers only | Separate plan | Via separate service | Paid add-on ($20/25k block) | Bundled in same account |
| Unsubscribes billable | No | No | No | Yes | No |
| Best for | Donor automation value | Lowest bill, ease of use | Events + fundraisers | Complex journeys, staffed teams | Free start + receipts |
At a like-for-like 5,000 contacts, effective prices run roughly: MailerLite Power ≈$48/mo (after 30%), GetResponse Starter ≈$14.50/mo at 2,500 (after 50%) scaling up the list ladder, Brevo $9–18/mo on sends, Mailchimp Essentials $75/mo before its 15% — the discount gap is where GetResponse and MailerLite pull away from Mailchimp as lists grow.
Verdict
- Most nonprofits should shortlist GetResponse first. A 50% nonprofit discount on a platform with real automation is the best value in the category. Verify your charity status, confirm the discount terms during signup, and price the tier that covers your automation needs — Starter’s single workflow may not be enough.
- Choose MailerLite when budget is the binding constraint and the team running email is small or volunteer-staffed. It’s the cheapest effective price, the easiest to learn, and it never charges you for unsubscribes.
- Choose Constant Contact when events are a fundraising engine. Built-in ticketing replaces a separate subscription, and phone support on every plan suits volunteer teams. Accept the annual prepay to unlock the full 30%.
- Choose Mailchimp only with dedicated staff who will genuinely use its automation depth — and apply for the 15% discount before you buy, then archive unsubscribes regularly so they stop billing you.
- Start free with Brevo if you’re small and mail infrequently, especially if you want donation receipts from the same account as your campaigns.
One last mechanism note, because it overrides brand choice: the platform matters less than two things being true in week one — a welcome automation that fires when someone joins, and a donation-triggered thank-you + second-ask sequence. A nonprofit running both on the cheapest tool here will raise more than one running neither on the most expensive. Set those up first, whichever row of the table you pick.
