Free Email for Nonprofits: What's Actually Free (2026)

Last updated: April 21, 2026

TL;DR: Most "free" email plans for nonprofits stop being free once you pass 250-500 contacts, then hidden costs pile up fast. Mailchimp now caps free at 250 contacts, MailerLite at 500, and Brevo's paid plan paradoxically reduces your contact allowance. Groupmail offers a genuine free tier (500 contacts, 1,000 emails/month, human support) and a $15/month upgrade with unlimited contacts and zero application paperwork. We tested every major free plan and mapped every contact cap, branding restriction, and gotcha so you can pick the right tool the first time.

Every nonprofit director has heard the pitch: "Send email for free!" But free plans have shrunk dramatically over the past three years. We tested seven platforms to find out what "free" actually means — and where the bills start piling up.

What Does "Free" Actually Mean for Nonprofit Email Software?

There are three types of "free" in email software, and only one of them means you won't eventually get a bill.

The first is a truly free tier — a permanent plan with real features and no expiration date. The second is a free trial that expires after 14-30 days, forcing you onto a paid plan. The third is free-with-strings: the plan technically costs nothing, but branding is forced on every email, contact limits are tiny, or essential features like scheduling and templates are locked behind a paywall.

Here is the reality most nonprofits face. M+R Benchmarks 2025 reports the average nonprofit email list contains 72,873 contacts. Most free plans cap you at 250-2,500 contacts — a fraction of what established organizations need. Meanwhile, Neon One's 2024 Nonprofit Communications Trends report found that 67% of nonprofits spend under $500 per year on email tools. Free plans matter enormously to this audience, which is exactly why the fine print matters so much.

We tested seven free plans and mapped every hidden cost, contact limit, and gotcha so you do not have to.

How Do the Free Plans Compare at a Glance?

Groupmail, EmailOctopus, and Brevo offer the most usable free tiers — but only Groupmail includes templates and human support at no cost.

The table below shows exactly what each platform gives you on its free plan. Pay attention to the "Human Support on Free?" column — when something goes wrong the week before your annual gala, that column matters more than anything else.

Constant Contact eliminated its free plan entirely in 2025. If you have been counting on that option, it no longer exists.

What Do You Actually Get with Groupmail's Free Plan?

Groupmail's Free plan gives nonprofits 500 members, 1,000 emails/month, a simple editor with templates, and human email support — no credit card, no trial expiration.

Setting up Groupmail takes about ten minutes. You get one list, a simple drag-and-drop editor with ready-made templates, and managed email delivery on every plan. That last part matters: Groupmail handles the technical sending infrastructure for you. There is no DNS configuration, no SPF records to set up, no deliverability headaches to troubleshoot. You write your update, pick your members, and send.

The Free plan includes Groupmail branding on your emails. If you need that removed, the Community plan ($15/month) removes it and also unlocks unlimited contacts, unlimited lists, scheduled sending, attachments, and AI writing help. That $15/month price stays well under the $500 annual board-approval threshold most nonprofits deal with.

Need extra capacity for a year-end appeal or event? Groupmail offers credit top-ups at $5 per 1,000 additional emails, available on every plan including Free. You only pay for what you use beyond your included limit.

Key Takeaway: Groupmail is the only free email plan tested that includes both templates and human email support at no cost. Every other free plan gates at least one of those features.

What's Really Free on Mailchimp's Free Plan?

Mailchimp's free plan shrank to 250 contacts and 500 emails/month in January 2026 — down from 2,000 contacts in 2022.

The erosion has been dramatic. In 2022, Mailchimp offered 2,000 contacts on its free plan. By 2023, that dropped to 500 contacts. As of January 2026, free users get just 250 contacts and 500 emails per month. For a detailed timeline, see our article on Mailchimp free plan changes in 2026.

What you lose on free: no automation, limited templates, Mailchimp branding on every email, and no scheduled sending. Support is email-only for the first 30 days, then gone entirely.

The bigger problem comes when you upgrade. Mailchimp counts all contacts — subscribed, unsubscribed, and non-subscribed — toward your plan limit. M+R Benchmarks 2025 found nonprofits average a 9.7% unsubscribe rate. That means a 5,000-contact list accumulates roughly 485 zombie contacts per year you are still paying for. Our Mailchimp nonprofit pricing breakdown covers this in detail.

Mailchimp holds a 2.8/5 on Trustpilot from 1,348 reviews. Its 15% nonprofit discount — the lowest among major competitors — requires a 501(c)(3) determination letter and must be requested before purchasing a paid plan. There is no retroactive application.

What's missing: At 250 contacts and 500 emails, Mailchimp's free plan is essentially a demo. A small nonprofit with 300 members is already forced onto a paid plan from day one.

Is MailerLite's Free Plan Worth It for Nonprofits?

MailerLite offers 500 subscribers and 12,000 emails/month for free — generous on volume, but forced branding, no templates, and no support after 14 days.

MailerLite's free plan used to allow 1,000 subscribers. In September 2025, that was halved to 500. If you have been considering MailerLite and your list recently crossed 500, see our guide to MailerLite free plan alternatives.

The 12,000 emails per month is genuinely generous for a free tier — far more than any other platform offers at no cost. But the trade-offs are real. Every email carries MailerLite branding. You cannot access custom templates. And support disappears entirely after your first 14 days.

For nonprofits considering MailerLite's paid plans, the 30% nonprofit discount sounds good on paper. However, MailerLite's legal terms (Section 3.4) state: "The Discount cannot be combined with any other discounts." That means you must choose between the 30% nonprofit discount or the annual billing discount — you cannot stack them. You also need to contact support within your 14-day trial with a 501(c)(3) letter or government recognition document to qualify.

What's missing: MailerLite is a good tool, but it is built for everyone — freelancers, e-commerce shops, bloggers. It is not purpose-built for community organizations. The free plan's lack of support after two weeks is a real problem for nonprofits with volunteer staff who might not set everything up in the first fortnight.

What Are Brevo's Hidden Costs for Nonprofits?

Brevo's free plan allows unlimited contacts and 300 emails/day (~9,000/month), but upgrading to the paid Starter plan actually caps your contacts at 500.

On the surface, Brevo's free tier looks like the most generous option. Unlimited contacts. Around 9,000 emails per month. The catch is Brevo branding on every email and the 300-per-day sending cap, which makes it impossible to send a single blast to a large list.

The real trap emerges when you try to upgrade. Brevo's paid Starter plan ($9/month) caps contacts at 500. You read that correctly — upgrading actually reduces your contact allowance compared to the free plan. A nonprofit with 3,000 members wanting to send one monthly update would need approximately the $49/month tier just to store all their contacts.

It gets worse. Brevo auto-upgrades your plan if you exceed the contact limit, increasing your bill without explicit approval. For a nonprofit running on a tight budget, an unexpected billing jump can cause real problems. Brevo's 15% nonprofit discount applies only to Enterprise plans — irrelevant for small and mid-sized nonprofits.

What's missing: Brevo's free plan works if your list is small enough to send 300 emails per day and you never need to upgrade. The moment you outgrow that, the pricing becomes confusing and potentially expensive. Groupmail offers unlimited contacts on every paid plan with no auto-upgrades and no surprise bills.

How Do EmailOctopus and Buttondown Compare on Free?

EmailOctopus has the most generous free tier at 2,500 subscribers and 10,000 emails/month, while Buttondown's free plan suits personal newsletters but not organizations.

EmailOctopus deserves credit here. Its free plan offers 2,500 subscribers and 10,000 emails per month — the highest contact limit of any free tier we tested. The trade-off is EmailOctopus branding on all emails and a fairly basic feature set with limited automation and reporting. A 20% lifetime nonprofit discount is available on the Pro plan, but you need to contact support to get it.

Buttondown takes a different approach. Its free plan caps at just 100 subscribers — too small for nearly any nonprofit. The 50% nonprofit discount is the most generous percentage among the tools we tested, but add-ons for tagging ($9/month), analytics ($29/month), and automations ($49-$79/month) escalate the total cost quickly and unpredictably.

Neither EmailOctopus nor Buttondown offers the handover call or migration assistance that volunteer-run nonprofits need. When the person managing your email list leaves — and in nonprofits, that person always eventually leaves — you are on your own.

What's missing (EmailOctopus): Limited automation and basic reporting may frustrate nonprofits who need to track open rates across different member segments. No migration or onboarding support.

What's missing (Buttondown): The 100-subscriber free plan is essentially a personal newsletter tool. Most nonprofit chapters, even small ones, will outgrow this immediately. The add-on pricing model makes budgeting difficult.

What Hidden Costs Do Most Nonprofits Miss?

The biggest hidden cost is not the plan price — it is paying for contacts who unsubscribed but still count toward your limit.

Five hidden costs catch nonprofits off guard:

• Unsubscribed contact billing. Mailchimp counts all contacts — subscribed, unsubscribed, and non-subscribed — toward your plan limit. Over time, this inflates your bill for people who will never open your emails again. If you are looking for better alternatives to Mailchimp's free plan, this is often the tipping point.
• Branding removal fees. Many free plans charge $9-15/month just to remove their logo from your emails. That is a recurring cost that adds up to $108-180 per year for something your members never asked to see in the first place.
• Forced plan upgrades at contact thresholds. Brevo auto-upgrades your plan without explicit approval when you exceed contact limits. Mailchimp does the same when you cross a tier boundary. A membership drive that adds 200 new contacts could trigger an immediate billing increase.
• Nonprofit discount paperwork and time cost. Gathering 501(c)(3) letters, submitting applications within trial windows, waiting for approval — this is unpaid staff time. For a volunteer-run organization, that time has real value.
• Volunteer turnover. Nonprofit Tech for Good reports the average nonprofit has 1.5 staff members managing digital communications. When that person leaves, the institutional knowledge goes with them — passwords, list organization, template setup, sending schedules. Rebuilding that costs far more than any monthly plan fee.

Watch out: The cheapest plan is not always cheapest at your actual contact count. A $9/month plan that caps at 500 contacts costs more than a $15/month plan with unlimited contacts once your list hits 501.

What Does Each Tool Really Cost at 1,000, 5,000, and 10,000 Contacts?

At 5,000 contacts, Mailchimp costs $69/month while Groupmail stays at $15/month with unlimited contacts on every paid plan.

Free plans only tell half the story. The table below shows what you will actually pay as your nonprofit grows. This is where the pricing differences become dramatic.

Pricing last verified April 2026. Groupmail paid plans include 5,000 emails/month with credit top-ups at $5/1,000 additional emails.

The pattern is clear. Every competitor's price climbs as your list grows. Groupmail stays flat at $15/month because every paid plan includes unlimited contacts. For a nonprofit with 5,000 members, that is $648 per year in savings compared to Mailchimp Standard — and $288 per year compared to MailerLite.

How Do Nonprofits Actually Get Their Discounts?

Most nonprofit discounts require documentation, support tickets, and careful timing — Groupmail's $15/month Community plan is the default price with no application needed.

The nonprofit discount landscape is surprisingly complicated. TechSoup, the leading nonprofit software procurement resource, routinely notes that many organizations miss available discounts simply because the application process is too burdensome for volunteer-run teams.

Here is how each platform actually works:

Pricing last verified April 2026.

The pattern is worth noting. Every competitor requires some form of application, documentation, or special timing to access nonprofit pricing. Groupmail's Community-First pricing means $15/month is the price — for churches, schools, associations, and nonprofits alike. No 501(c)(3) letter. No trial window. No hoops.

Which Free Email Plan Is Best for Your Nonprofit?

For most nonprofits, Groupmail's free plan is the best starting point — and the $15/month upgrade gives you unlimited contacts with no application paperwork.

The right choice depends on where you are today and where you are heading. Here is a simple decision framework:

• Under 100 members: Groupmail Free works well. Buttondown's free plan technically works at this size but is very limited for organizational use.
• 100-500 members: Groupmail Free gives you everything you need — templates, human support, managed delivery.
• 500-2,500 members: EmailOctopus Free offers the highest contact allowance. But if you value support and simplicity, Groupmail's Community plan at $15/month gives you unlimited contacts and a much simpler experience.
• 2,500+ members: Groupmail Community ($15/month) is the clear choice. You would pay $46-69/month or more on Mailchimp or MailerLite at this list size.

If simplicity and human support are your priorities, Groupmail is the answer at every list size. If you need maximum free email volume and can live without support, EmailOctopus is a reasonable starting point. If you need automation workflows, MailerLite is capable — but expect to pay for it.

One more thing worth mentioning: when the volunteer who manages your email eventually moves on, Groupmail's Continuity plan ($29/month) includes an annual handover call where Groupmail's team helps the new person take over. No other platform offers this. For our full guide to the best email software for nonprofits, including paid options, we cover this in more depth.

FAQ

Why is Groupmail so affordable for nonprofits?

Groupmail uses a Community-First pricing model. The $15/month Community plan is the default price for every organization — not a discounted rate that requires paperwork. There are no application forms, no 501(c)(3) documentation requirements, and no hoops to jump through. Groupmail has been EU-based since 1996 with a sustainable business model built around serving organizations, not venture-capital growth targets. Every paid plan includes unlimited contacts, so your price never increases as your membership grows.

Does Mailchimp charge for unsubscribed contacts?

Yes. Mailchimp counts all contacts — subscribed, unsubscribed, and non-subscribed — toward your plan limit. M+R Benchmarks 2025 found that nonprofits average a 9.7% unsubscribe rate, meaning a 5,000-contact list accumulates roughly 485 contacts per year that you cannot email but are still paying for. Groupmail does not charge for unsubscribed contacts on any plan.

What happens when I exceed my contact limit on Mailchimp?

Mailchimp automatically moves you to a higher-priced tier when you exceed your plan's contact limit. There is no grace period — the upgrade and billing change happen immediately. This can be particularly surprising for nonprofits running membership drives or events where sign-ups spike temporarily. Groupmail's paid plans include unlimited contacts, so this situation never arises.

Is Brevo really free for nonprofits?

Brevo's free plan offers unlimited contacts and 300 emails per day, which sounds generous. However, upgrading to the paid Starter plan actually caps your contacts at 500 — fewer than what you had for free. A nonprofit with 3,000 members would need approximately the $49/month tier just to store all their contacts. Brevo's nonprofit discount of 15% only applies to Enterprise plans, making it irrelevant for most small and mid-sized nonprofits.

Which free email plan has the highest contact limit?

EmailOctopus offers the most generous free tier at 2,500 subscribers and 10,000 emails per month. However, it includes EmailOctopus branding on all emails and has limited automation features. Brevo technically allows unlimited contacts on its free plan but caps daily sends at 300 emails. Groupmail's free plan allows 500 members with 1,000 emails per month and includes human email support — the only free plan tested that does.

Do I need a 501(c)(3) letter to get nonprofit email pricing?

It depends on the platform. Mailchimp requires a 501(c)(3) determination letter before purchasing, MailerLite requires documentation within a 14-day trial window, and EmailOctopus requires contacting support with proof of nonprofit status. Constant Contact requires prepaying 6-12 months. Groupmail does not require any documentation — $15/month is the default Community plan price for every organization, no application needed.

Can I send more than my monthly limit on Groupmail's free plan?

Yes. Groupmail offers credit top-ups at $5 per 1,000 additional emails, available on every plan including Free. This is useful for nonprofits that normally send under 1,000 emails per month but need extra capacity for events, year-end appeals, or fundraising drives. You only pay for what you use beyond your included limit.

What happens when our volunteer who manages email leaves?

This is one of the biggest hidden costs in nonprofit email — the institutional knowledge that walks out the door when a volunteer or staff member departs. Groupmail's Continuity plan ($29/month) includes an annual handover call where Groupmail's team helps the new volunteer take over the account, understand the setup, and start sending confidently. No other email platform offers this kind of transition support specifically designed for volunteer-run organizations.

Conclusion

"Free" in nonprofit email software rarely means free once your list grows past 250-500 contacts. From Mailchimp's shrinking free plan to Brevo's paradoxical contact caps to MailerLite's vanishing support, every platform has fine print that eventually turns into a bill.

Groupmail takes a different approach: a genuine free tier with human support, and a $15/month upgrade that includes unlimited contacts with no application paperwork, no codes to chase, and no documentation requirements. For most nonprofits in 2026, that is the simplest and most honest deal available.
