Best Mailchimp Alternatives for Nonprofits (2026): Cost, Features and Discounts Compared

If you are looking at Mailchimp alternatives for nonprofits, it is usually for one of two reasons. The bill grew faster than the donor list, or the plan you can afford is missing features you need, like automated welcome series or decent segmentation. This guide compares eight realistic options side by side: what they cost at roughly 10,000 and 50,000 contacts, which ones offer a nonprofit discount, how well they handle donor journeys, and how much technical work each one asks of a small team. All prices are as of November 2026 and were checked on each vendor's own pages. Where a vendor does not publish a number we could confirm, we describe the pricing model instead.

Why nonprofits look for Mailchimp alternatives

Mailchimp is still the default for many small organizations, and for good reason: the editor is polished, it connects to a lot of tools, and most staff and volunteers have used it before. The friction shows up in three places.

• Cost that tracks list size. Mailchimp prices its paid plans by contact count, and as of November 2026 its paid plans start at $13/month (Essentials) and $20/month (Standard) for the smallest tier, rising as contacts grow. Unsubscribed and lapsed donors you keep for reporting can still push you into a higher tier. We break down the real numbers in what you actually pay with the Mailchimp nonprofit discount.
• A modest discount. Mailchimp offers nonprofits and charities 15% off, which you request from its billing team after signing up.
• A small free plan. The free plan is limited to 250 contacts and 500 sends per month, so most organizations outgrow it within the first campaign season.

None of that makes Mailchimp a bad choice. It makes it a choice worth re-checking every year or two, especially before a big season like Giving Tuesday or year-end appeals. For a direct feature-by-feature look, see our eMailBase vs Mailchimp comparison.

How we compared the alternatives

We judged every tool on the criteria that come up most often when development and communications staff evaluate email platforms:

1. Cost at about 10,000 and 50,000 contacts. These are common sizes for a small local nonprofit and a mid-sized regional one. Where a vendor only shows prices through a slider we could not confirm, we explain the model rather than guess.
2. Nonprofit discount. Percentage, how to claim it, and whether it stacks with annual billing.
3. Automation for donor journeys. Can you build a donor welcome series, a lapsed-donor win-back, and a year-end fundraising sequence without workarounds?
4. Ease of use for small teams. Can a one-person comms team run it without a developer?
5. Deliverability controls. Authentication (SPF, DKIM, DMARC), sending reputation, and visibility into bounces and complaints.
6. Data ownership. How easily you can export everything, and whether your list and sending reputation are tied to the vendor.

One thing we deliberately left out: invented open-rate or donation-lift figures. Vendors rarely publish comparable numbers, and your results depend far more on your list and your writing than on the platform.

The 8 best Mailchimp alternatives for nonprofits

1. Brevo

Brevo (formerly Sendinblue) prices paid plans mainly by monthly email volume rather than by how many contacts you store. Its free plan allows 300 emails per day, and Brevo's own pages list the Starter plan at $9/month for 5,000 emails as of November 2026. Brevo doesn't publish a nonprofit discount; ask its sales team.

Best for: organizations with a large list of past supporters but a modest sending schedule, for example a quarterly newsletter plus a few appeals. Storing contacts is cheap; sending is what you pay for.

Watch out for: advanced automation and some reporting features sit on higher tiers, and costs rise quickly if you increase sending frequency during campaign season. We go deeper in Mailchimp vs Brevo for nonprofits.

2. MailerLite

MailerLite is the closest thing to "Mailchimp, but simpler and cheaper." As of November 2026 its free plan covers 250 subscribers and 2,500 emails per month, the Comfort plan starts at $12/month, and the Power plan starts at $25/month, with prices rising by subscriber count. Nonprofits get 30% off paid plans after selecting "nonprofit" at signup and sending proof of status. Per MailerLite's billing help, discounts do not stack, so the 30% replaces the annual-billing discount rather than adding to it.

Best for: small teams that want a clean editor, landing pages, and straightforward automations with almost no learning curve.

Watch out for: the free plan is now small, and pricing is still contact-based, so a list of 50,000 will cost noticeably more than a list of 10,000. See Mailchimp vs MailerLite for nonprofits for a full breakdown.

3. Constant Contact

Constant Contact has served nonprofits for a long time and offers event tools, phone support, and a familiar editor. Pricing is tiered by contact count. Its published nonprofit terms give 20% off for a 6-month prepayment and 30% off for a 12-month prepayment, with no discount on month-to-month billing. US organizations need an IRS determination letter, and Constant Contact asks you not to buy a prepaid plan before your nonprofit pricing is confirmed, because the discount is not applied retroactively.

Best for: organizations that value live phone support and run frequent in-person events.

Watch out for: the discount requires paying up front, which can be hard for small budgets, and automation is less flexible than in tools built around journeys. Compare the two incumbents in Constant Contact vs Mailchimp for nonprofits.

4. Kit (formerly ConvertKit)

Kit is built for creators, but it is worth a look for nonprofits whose email program centers on one voice, such as a founder's newsletter or a storytelling-led cause. As of November 2026 Kit's free plan allows up to 10,000 subscribers, and paid plans are listed at $33/month (Creator) and $66/month (Pro, with a first-year promotion) for 1,000 subscribers, rising with list size. We found no nonprofit discount on Kit's pricing page.

Best for: newsletter-first organizations that want a generous free tier and tag-based automation.

Watch out for: paid plans get expensive at larger list sizes, and the product is designed around creators selling products, not donors giving.

5. Action Network

Action Network is a nonprofit-built platform for progressive organizations, combining email, petitions, events and fundraising pages. It bills per email sent: the Movement plan is $1.25 per 1,000 emails with a $15/month minimum (covering the first 12,000 emails), and the Network plan for federated organizations is $2.50 per 1,000 with a $125/month minimum, as of November 2026. There are no setup fees or contracts, and lapsed partners can keep and export their data.

Best for: advocacy and organizing groups that need petitions, letter campaigns and email in one place.

Watch out for: it is open only to progressive individuals and organizations, and per-email billing adds up if you send several times a week to a large list.

6. Sendy (self-hosted, with Amazon SES)

Sendy is a one-time-license newsletter app you install on your own web server. As of November 2026 the license is $69 one-time, and sending runs through Amazon SES (with native support for a few other providers), which you pay separately at SES rates.

Best for: organizations with a technical volunteer or staff member who is comfortable managing a PHP/MySQL server.

Watch out for: you are responsible for hosting, updates, backups and security. Automation is basic compared with journey builders, and there is no vendor support team to call during a year-end deadline.

7. eMailBase (bring your own sending server)

eMailBase is our product, so weigh this section accordingly. It is a "BYO" platform: you pay eMailBase a software subscription and pay for email delivery directly to your own provider, such as Amazon SES, SendGrid, Mailgun or Gmail/SMTP. Amazon SES lists outbound email at $0.10 per 1,000 emails on à la carte pricing as of November 2026 (new accounts start on the $0.16 Essentials plan unless you switch), with separate charges for attachment data and optional dedicated IPs. (New to the model? Read what BYO email means.)

Plans as of November 2026, monthly billing: Starter $4.99 (5,000 contacts, 5 automation workflows), Growth $9.99 (20,000 contacts, 20 workflows, REST API, 3 users), Pro $19.99 (50,000 contacts, 50 workflows, 5 users) and Business $34.99 (200,000 contacts, unlimited automations, 25 users). Billing every 6 months saves 20% and annual billing saves 35%. Every plan has a contact limit. Full details are on the eMailBase pricing page.

Best for: cost-conscious organizations with 10,000+ contacts that want visual donor journeys, multi-provider sending with failover, and deliverability checks, and that have someone comfortable with DNS records.

Watch out for: eMailBase has no announced nonprofit discount, no built-in donation forms or payment processing, and no named CRM integrations (you connect via CSV import, REST API or webhooks). You also need a sending provider account and DNS setup before your first campaign. If nobody on the team can do that, a hosted tool like MailerLite is a safer choice.

8. Your donor CRM's built-in email

Many donor management systems include basic email tools. If you already pay for one, it is worth testing before adding another subscription. Pricing and capabilities vary widely by vendor, so check your contract rather than relying on a general figure.

Best for: teams whose biggest pain is keeping gift data and email lists in sync.

Watch out for: built-in email modules are often less capable for design, automation and deliverability reporting than dedicated email platforms.

What it costs at 10,000 and 50,000 contacts

Contact-based tools (Mailchimp, MailerLite, Constant Contact, Kit) all charge more as the list grows, whether or not you email everyone. Their exact prices at these sizes are shown through pricing sliders, so check the current figure for your list size before budgeting, then apply the nonprofit discount.

For volume-based and BYO tools, the math is easier to show. Assume four emails per contact per month (one newsletter plus three appeals or updates):

• 10,000 contacts: about 40,000 emails a month. On Amazon SES that is about $4 in sending fees. Paired with eMailBase Growth ($9.99), that is roughly $14 a month before SES extras. On Action Network's Movement plan, 40,000 emails is about $50.
• 50,000 contacts: about 200,000 emails a month. SES sending is about $20; with eMailBase Pro ($19.99) that is roughly $40 a month. On Action Network Movement, about $250. Sendy would be the $69 license once, plus the same SES fees and your server hosting.

These are illustrations, not quotes. Your sending frequency changes everything, and peak months like December can double volume.

Which Mailchimp alternative should your nonprofit choose?

Very small organizations (under 2,000 contacts, no budget)

Start with a free plan. Kit's free tier is the most generous by subscriber count, and Brevo's daily allowance works if you send a monthly newsletter. Our guide to free email marketing for nonprofits compares the limits in detail.

Small teams with no technical help

Choose MailerLite or Brevo. Both are easy to learn (MailerLite offers a 30% nonprofit discount; Brevo doesn't publish one, so ask its sales team), and both handle a welcome series and basic segmentation. If live phone support matters more than price, Constant Contact with a 12-month prepay is a reasonable choice.

Growing organizations with 10,000 to 50,000 contacts

This is where pricing models diverge the most. If you have a technical volunteer, IT contractor, or agency who can set up SPF, DKIM and DMARC, a BYO setup like eMailBase on Amazon SES can cut the monthly bill substantially while giving you visual automation. If not, compare MailerLite's discounted price at your list size with Brevo's volume pricing at your sending frequency.

Advocacy and organizing groups

If you are a progressive organization running petitions and calls to action, Action Network is designed for exactly that work, and per-email billing is fair for groups that send in bursts.

Organizations with in-house developers

Sendy is the cheapest way to send, if you are happy to maintain a server. If you want the low sending cost without running the software yourself, plus automation and multi-provider failover, eMailBase is the middle path.

Switching without losing donors

The platform matters less than how you move. Export contacts with tags, groups and custom fields (gift dates, amounts, campaign source), re-import them with matching fields, and authenticate your sending domain before the first send. Then send to your most engaged supporters first and expand over a couple of weeks so mailbox providers see a steady, healthy pattern. Our step-by-step guide on how to migrate your donor list from Mailchimp covers each step, including what to do with unsubscribes so you never email someone who opted out.

After the move, rebuild your core automations first:

• A donor welcome email series for new supporters.
• Donor retention emails such as gift anniversaries and impact updates.
• Seasonal sequences for Giving Tuesday and year-end.

If you need fresh copy for those campaigns, our collection of donation appeal email examples is a good starting point, and the nonprofit email marketing guide covers the full program, from list growth to reporting.

The right Mailchimp alternative depends on your list size, how often you send, and who on your team can handle setup. If simplicity matters most, MailerLite with its 30% nonprofit discount or Brevo's volume pricing will serve you well. If you are an advocacy group, look at Action Network. If your list is growing past 10,000 and you have someone comfortable with DNS, a bring-your-own-server platform keeps costs low while giving you real donor-journey automation. Price two or three options against your actual active list, and test one with a real campaign before you commit.
