Mailchimp's real nonprofit problem isn't the 15% charity discount. It's the pricing model: every contact you add and every email you send moves the bill up, and your donor list is supposed to grow. The right alternative for a nonprofit doesn't just match Mailchimp feature-for-feature. It removes the scaling penalty entirely.

This guide ranks 10 Mailchimp alternatives by total annual cost at the contact size most small and mid-size nonprofits actually run (5,000 and 10,000), then breaks down which platforms make sense above that price floor. The only one where unlimited contacts, unlimited sends, automated tax receipts, and a built-in donor CRM stay at $0 is Zeffy, and a native Mailchimp importer means switching takes minutes, not a quarter.

‍

1. Zeffy: The only $0 platform on this list, at any list size

Zeffy is a fundraising platform that includes free email tools bundled with a built-in donor CRM, automated tax receipts, and pre-filled donation form links you can drop directly into any campaign. For a nonprofit whose headline pain is "the bill scales with my donor list," it is the only platform on this list where unlimited contacts and unlimited sends stay at $0 as your list grows.

Email blasts go out to up to 11,000 contacts per send, BCC'd for privacy. The native Mailchimp importer (direct connect or CSV) means migration takes a few minutes, not a quarter.

‍

Using Zeffy for nonprofit email marketing

A typical setup looks like this: import your Mailchimp list, create a segment in the donor CRM (for example, "donors who gave in the last 12 months" or "event attendees from your spring gala"), draft a campaign in the drag-and-drop editor, drop in a pre-filled donation form link, and schedule the send. Open rate, click rate, and donations attributed to the email all track back to the donor record.

The Community Music School of Santa Cruz switched from a tool that eliminated its free tier and saved over $2,000 in fees the first year. Full story below.

What Zeffy does:

• Unlimited contacts and unlimited sends at $0, with no contact-tier upcharge

• Built-in donor CRM with segmentable lists that auto-update as contacts meet criteria

• Automated tax receipts triggered by donation

• Pre-filled donation form links inside email campaigns

• Email blasts up to 11,000 contacts per send, BCC'd for privacy

• Drag-and-drop email builder, templates, scheduled sends, and open/click/donation tracking

• Embeddable signup forms that sync new subscribers to your lists

• Native Mailchimp importer (direct connect or CSV)

What Zeffy doesn't include:

• No visual automation workflow builder, no A/B testing, no predictive sending

• No landing-page builder

• No published deliverability rate (Zeffy does not benchmark inbox placement against pure ESPs)

If your primary need is best-in-class email marketing sophistication and you're not running a fundraising program alongside it, the pure ESPs further down this list (ActiveCampaign in particular) will serve you better. If your primary need is to stop paying a per-contact bill that climbs every quarter, Zeffy is the only option here.

Pricing: $0. Every nonprofit, every list size, forever. No platform fee, no transaction fee, no credit card fee. Ever.

‍

2. MailerLite: The closest budget Mailchimp clone for small nonprofits

MailerLite is the closest thing to a budget Mailchimp clone for a small nonprofit. The drag-and-drop editor is clean, the free tier is usable for getting started, and the paid tier is one of the cheaper per-contact prices on this list. The bill still climbs with your contact count, and the live pricing page (verified 2026-06-02) does not publish a nonprofit discount.

Standout features:

• Drag-and-drop email editor

• Segmentation and personalization

• Automated workflows on paid plans

• Real-time analytics

Caveats:

• Free tier caps monthly sends and limits templates and support; see mailerlite.com/pricing for current limits

• No nonprofit discount published on the live pricing page (2026-06-02)

• Pure ESP: no tax receipts, no donor records, no donation forms

Who it suits: Small nonprofits with under roughly 5,000 contacts who want a Mailchimp replacement at a lower price and don't need fundraising features in the same tool.

‍

3. Brevo (formerly Sendinblue): Volume-based pricing plus SMS in one console

Brevo prices by send volume instead of contact count, which is genuinely useful for nonprofits with big lists who send infrequently. The free plan holds 500 contacts and roughly 300 sends per day per brevo.com/pricing (verified 2026-06-02). The real differentiator is SMS in the same console: a nonprofit running event reminders or volunteer call-ups can send an email and a text from one tool with one contact record.

Standout features:

• Email priced by send volume, not contact count

• SMS marketing in the same console (event reminders, volunteer alerts)

• Contact-level marketing CRM

• Automation workflows on paid plans

Caveats:

• Free plan caps daily sends and excludes A/B testing and full automation

• No published nonprofit discount on the standard pricing page; check current program eligibility before signing

• Pure ESP: no tax receipts or donation forms

Who it suits: Nonprofits running event reminders or rapid-response advocacy where text messages matter as much as email.

‍

4. ActiveCampaign: The deepest automation workflow builder on this list

ActiveCampaign is the platform you choose when your nonprofit's email program is more than a monthly newsletter. The visual workflow builder is best-in-class on this list, A/B testing is built in, and predictive sending picks the optimal time to deliver each email. A classic nonprofit use case: a lapsed-donor re-engagement sequence that fires automatically 60 days after a donor's last gift, with a different message track for monthly vs. one-time givers and an automatic exit once a new gift comes in.

Standout features:

• Visual automation workflow builder (the deepest on this list)

• A/B testing and predictive sending

• Strong marketing CRM

• Documented Mailchimp import tool

Caveats:

• No free plan; trial only

• No nonprofit discount published on the live pricing page (verified 2026-06-02); check current program eligibility

• Pure ESP: no tax receipts or donation forms

Who it suits: Advocacy organizations and larger nonprofits running multi-step donor sequences who will actually use the workflow depth.

‍

5. EmailOctopus: A generous free tier built for high-volume newsletters

EmailOctopus is built on Amazon SES rails, which keeps per-email cost low and lets the free tier be unusually generous. The free plan includes 2,500 subscribers and 10,000 emails per month per emailoctopus.com/pricing (verified 2026-06-02). If your nonprofit sends a weekly newsletter to a 2,000-contact list and you don't need fancy automation, the free tier may carry you indefinitely.

Standout features:

• 2,500 subscribers and 10,000 emails/month on the free tier

• Low per-email cost on paid tiers (SES rails)

• Simple, clean interface

Caveats:

• Limited automation builder compared to ActiveCampaign or Mailchimp

• Pure ESP: no tax receipts, no donation forms, no donor-specific CRM

• No published nonprofit discount

Who it suits: Nonprofits whose program is a high-volume newsletter and who don't need automation depth or fundraising features.

‍

6. Constant Contact: Strong support and training for teams new to email marketing

Constant Contact's draw is human support. The training resources are extensive, phone support is included, and the live page (2026-06-02) cites a 20% nonprofit discount on a 6-month prepay and 30% on a 12-month prepay. There's no free plan and per-contact pricing scales fast: the live page cites roughly $120/month at the 5,000-contact tier before discount.

Standout features:

• Extensive training resources, webinars, and phone support

• Nonprofit prepay discount (per live page: 20% / 30%)

• Drag-and-drop editor, automation, contact CRM

Caveats:

• No free plan (trial only)

• Pricing scales with contact count

• Pure ESP: no tax receipts or donation forms

Who it suits: Small nonprofits where staff are new to email marketing and the value of training and phone support outweighs the price.

‍

7. HubSpot: Worth it only if your contact data already lives there

HubSpot is a marketing/sales CRM with email as one channel among many. The free CRM tier exists and includes a capped number of monthly email sends (live page cites roughly 2,000/month, verified 2026-06-02). Above that, Marketing Hub Starter at 5,000 contacts runs into the hundreds of dollars per month before any discount, and the live pricing page does not publish a nonprofit program. If you've already standardized on HubSpot for donor relationships, email lives in the same place. If email is your primary need, it's overkill.

‍

‍

Standout features:

• Integrated marketing/sales CRM with email

• Strong workflows when contact data already lives in HubSpot

• Free CRM tier with limited email sends

Caveats:

• No nonprofit discount published on the live pricing page (verified 2026-06-02); check current program eligibility before signing

• Pricing climbs fast above the free tier

• General-purpose CRM: no IRS-compliant tax receipts, no donation forms

Who it suits: Larger nonprofits already running multi-channel donor relationships on HubSpot.

‍

8. Moosend: Unlimited sends on a cheap paid plan once free tiers run out

Moosend is the budget pick when MailerLite's free tier runs out and ActiveCampaign is too expensive. Paid plans include unlimited sends and decent automation. There's a 30-day trial but no permanent free plan as of 2026-06-02. See moosend.com/pricing for current entry pricing before signing.

Standout features:

• Unlimited sends on paid plans

• Automation builder

• Cheap entry tier

Caveats:

• No permanent free plan (30-day trial only)

• No published nonprofit discount

• Pure ESP: no tax receipts or donation forms

Who it suits: Cost-sensitive nonprofits past the free-tier ceilings of MailerLite and Brevo who don't need nonprofit-specific features.

‍

9. Campaign Monitor: Design-forward templates for brand-conscious nonprofits

Campaign Monitor is the design-forward pick. Templates are genuinely beautiful, the editor rewards a marketer with brand sensibility, and the live page (2026-06-02) cites a 15% nonprofit discount. Pricing is mid-market: the live page cites roughly $109/month at the 5,000-contact tier before discount, and there's no free plan.

Standout features:

• Best-in-class template design quality

• 15% nonprofit discount (per live page, 2026-06-02)

• Segmentation, automation, analytics

Caveats:

• No free plan

• Mid-market pricing even after discount

• Pure ESP: no tax receipts or donation forms

Who it suits: Nonprofits with in-house design or brand resources who want emails that look like a creative agency built them.

‍

10. Kit (formerly ConvertKit): Built for creator-led nonprofits with a personal-voice newsletter

Kit rebranded from ConvertKit in 2024 and is built for creators: authors, podcasters, founder-led personal brands. For a nonprofit with a strong founder or executive director who runs the email program as a personal-voice newsletter (think: an environmental nonprofit whose director is the face of the brand), Kit's sequence tools and landing pages fit well. There's no published nonprofit discount.

Pricing tiers per convertkit.com/pricing (verified 2026-06-02): Newsletter (Free), Creator ($33/mo or $390/year), Pro ($66/mo or $790/year). Re-verify under Kit branding before signing.

Standout features:

• Strong creator workflows: landing pages, sequences, paid subscriptions

• Free Newsletter tier

• Clean, writer-friendly editor

Caveats:

• No nonprofit discount published

• Creator-focused: no donation forms, no tax receipts, no donor CRM

• Limited automation on the free tier

Who it suits: Founder-led nonprofits running a personal-voice newsletter as the core engagement channel.

Why nonprofits are leaving Mailchimp in 2026

The hidden cost is the scaling penalty. Mailchimp's paid tiers price by contact count and send volume, both of which a nonprofit's email program is supposed to grow. A nonprofit with 5,000 contacts on Mailchimp's Standard plan pays roughly $100/month (approximately $1,200/year) before any discount applies, per mailchimp.com/pricing (verified 2026-06-02). The 15% charity discount shaves the number down but does not change the shape of the curve: every new donor on your list moves the bill up.

The free trial is genuinely limited. Per mailchimp.com/pricing (verified 2026-06-02), the free option is a 14-day trial capped at 6,000 emails per month with limited automation. For a nonprofit testing a single appeal it's workable. For ongoing donor communication it isn't a free tier in the way most readers expect when they search "free Mailchimp alternative."

Deliverability is a nonprofit-specific concern. Donation appeals trigger spam filters at higher rates than commercial promotional email. Platforms that aren't optimized for fundraising language and that don't have nonprofit-specific authentication practices can hurt inbox placement. This is a real reason nonprofits look for alternatives, though inbox-placement rates vary by list hygiene, authentication setup (SPF, DKIM, DMARC), and content as much as by platform.

The nonprofit-native gap is the biggest one. Mailchimp doesn't issue IRS-compliant tax receipts, doesn't store donor history, and doesn't link to donation forms. A nonprofit running Mailchimp typically pairs it with a separate fundraising tool, a separate donor CRM, and a separate receipt system. Zeffy bundles automated tax receipts, a donor CRM, and donation forms with email at $0, which removes both the bill and the toolchain sprawl.

How to choose the right email platform for your nonprofit

There's no universally right pick. Match the platform to the scenario:

• 1. Just starting out with under 1,000 contacts. You want a generous free tier you won't outgrow in a quarter. Zeffy (unlimited at $0), MailerLite (small-list free tier), Brevo (500-contact free plan with SMS), or EmailOctopus (2,500 subscribers, 10,000 sends/month) all qualify. If you also want fundraising in the same tool, Zeffy is the only one in this group that bundles it.

• 2. Growing nonprofit with 5,000+ contacts who also runs fundraising campaigns. Zeffy. The cost stays $0 as your list grows, and donation forms, tax receipts, and donor CRM are in the same tool as email.

• 3. Advocacy org needing advanced automation workflows. ActiveCampaign for the deepest visual workflow builder, or HubSpot if your contact data already lives there.

• 4. Mid-size nonprofit prioritizing template design and brand polish. Campaign Monitor. Pay the mid-market price for the template quality.

How to switch from Mailchimp without losing subscribers

The fear of losing the list is the number one reason nonprofits stay on Mailchimp longer than they should. The migration is more straightforward than it looks:

• 1. Export your Mailchimp list. In Mailchimp, open the audience you want to move, click "Export Audience," and download the CSV. This file is your safety net: keep a copy off the new platform until the cutover is complete.

• 2. Clean your list before importing. Remove obvious bounces, unsubscribed contacts, and duplicates. A smaller, healthier list improves deliverability everywhere you send it.

• 3. Set up your new platform and import. If you're moving to Zeffy, the native Mailchimp importer lets you connect your account directly or upload the CSV you just exported. Either path takes a few minutes. Import your Mailchimp contacts to Zeffy walks through the steps.

• 4. Re-confirm subscribers if compliance requires it. For GDPR-covered contacts or any list segment with unclear consent history, send a re-permission email from the new platform before your first campaign. Yes, you'll lose some addresses. The list you keep is the list that actually wants to hear from you.

• 5. Redirect any Mailchimp signup forms. Update the embed code on your website, donation pages, and event landing pages to point at your new platform's signup form. Keep the old Mailchimp audience active for 30 days as a backstop in case any form was missed.

Real results: How Community Music School saved $2,000

After their previous donor management system eliminated its free version, Community Music School of Santa Cruz, a nonprofit focused on music education, was left scrambling to find a replacement that would help them stay in touch with donors. They wanted a platform that was powerful and intuitive without paying any platform or transaction fees.

They switched to Zeffy. The platform let them run all of their fundraising activities, including email marketing, donation tracking, and ticket sales, in one place at $0.

The result: Community Music School of Santa Cruz saved over $2,000 in fees.

I love the ability to quickly email people who've attended any one of our past events, it's simple and the 'from' line in the customer's email is our name, so there's no confusion. I also appreciate the ability to embed the donation form or ticketing form into our website, it gives us a professional look. Finally, I couldn't ask for better customer service. My questions are always responded to promptly, and the team always seems to welcome suggestions for future improvements.
— Susan Willats, Community Music School of Santa Cruz

The features they use most: email campaigns to past event attendees, embedded donation and ticketing forms on their website, and donor records that stay in sync without manual updates.
