The best email marketing software for small nonprofits

MailerLite — best value and simplicity

MailerLite is ideal for nonprofits that want lovely emails and simple automations at a great price, with a generous free plan and an editor that's a joy to use. Landing pages, forms and automations come built in — perfect for a small team growing a supporter list affordably.

Brevo — email plus SMS, billed by send

Brevo bills by emails sent rather than list size, which suits nonprofits with a large supporter list they email periodically. It bundles email, SMS, automations and basic CRM — and SMS is handy for urgent appeals and event reminders.

Sender — affordable email and SMS

Sender delivers capable email and SMS marketing with a generous free tier and low-cost paid plans, plus automation for welcome and nurture sequences. For a budget-conscious nonprofit, its value is a real draw.

Constant Contact — support and nonprofit features

Constant Contact is a great fit for nonprofits that value hand-holding, with famously helpful support and useful event and list-management tools. It's not the cheapest, but for peace of mind and an approachable experience, many nonprofits happily use it.

Mailchimp — the familiar all-rounder

Mailchimp is the well-known option with broad features, automations and landing pages, and it offers nonprofit discounts. Pricing can climb as your list grows, so weigh it against the value picks — but it's a capable, familiar choice.

GetResponse — all-in-one with landing pages

GetResponse bundles email, automation, landing pages and even webinars in one platform, useful for nonprofits running campaigns and events. You can capture supporters with landing pages and nurture them with automated sequences, all in one place.

How to choose the right one

Want the best value and simplicity? MailerLite. Email a big list occasionally and want SMS? Brevo or Sender. Value support and event tools? Constant Contact. Prefer a familiar all-rounder with nonprofit discounts? Mailchimp. Want landing pages and webinars too? GetResponse. Most offer free plans or nonprofit pricing — start free and upgrade as your list and needs grow.

Getting started and engaging donors

Start by giving supporters a reason to subscribe — an impact update, a story, a way to help — and collect emails with a simple form or landing page. Set up a welcome sequence that introduces your mission and an automatic thank-you for donors, since a prompt, heartfelt thank-you is one of the biggest drivers of repeat giving. Send a regular newsletter sharing real impact — the people and outcomes your work makes possible — rather than only asking for money. Segment donors, volunteers and general subscribers so each gets relevant messages. Consistent, story-led email keeps supporters emotionally connected and giving.

Common email mistakes small nonprofits make

Only emailing to ask for money. Constant appeals cause fatigue. Lead with impact and stories so supporters stay engaged.

No thank-you automation. A prompt thank-you drives repeat giving. Automate it so no donor is ever left unacknowledged.

Not segmenting. Donors, volunteers and subscribers want different messages. Segment so each feels seen.

Ignoring the data. Your reports show what resonates. Use opens and clicks to refine your appeals and stories.

Overpaying. Many tools offer nonprofit discounts or generous free tiers. Don't spend budget you could put toward your mission.

Turning subscribers into recurring donors

The lifeblood of a sustainable nonprofit is recurring donors, and email is how you nurture supporters toward that commitment. It starts with the relationship: a strong welcome sequence, consistent impact stories, and prompt, personal thank-yous build the trust and emotional connection that make someone willing to give again. From there, make recurring giving an easy, natural next step — invite engaged supporters to become monthly donors, explaining exactly what a monthly gift makes possible in concrete terms. Automated sequences can nurture a one-time donor toward a second gift and then toward monthly giving, while segmentation lets you treat existing monthly donors differently, thanking and updating them rather than re-soliciting. Tools like MailerLite, Brevo and GetResponse make these donor journeys straightforward to build. Recurring donors give nonprofits predictable income to plan around and cost far less to retain than acquiring new ones, so the email work that converts and keeps them is among the highest-return activities a small nonprofit can invest in.

Telling your impact story that raises more

Nonprofits don't sell products — they invite people into a story of change, and email is the perfect medium for it. The organisations that raise the most through email are relentlessly focused on impact: instead of abstract statistics or constant asks, they show a specific person, project or outcome their supporters made possible, with photos and a human narrative. This storytelling makes donors feel the difference their giving creates, which is far more motivating than a plain appeal. Structure your emails around one clear story and one clear action, keep them warm and genuine rather than corporate, and always close the loop by reporting back on what past donations achieved — donors who see their impact give again. Segmentation and personalisation help each supporter feel individually valued, and A/B testing subject lines and content (which most of these tools support) helps you learn what moves your audience. Mastering impact storytelling in email, powered by an affordable, easy tool, lets even the smallest nonprofit build a loyal, generous community around its mission.

Frequently asked questions

What is the best free email marketing tool for a small nonprofit?

MailerLite offers one of the best free plans for nonprofits — generous limits plus automations, landing pages and forms at no cost. Sender and Brevo also have strong free tiers, with Brevo's send-based pricing especially friendly for occasional senders with large lists.

Do email platforms offer nonprofit discounts?

Several do. Mailchimp and Constant Contact offer nonprofit discounts, and tools like MailerLite, Sender and Brevo are affordable or free to begin with. Always check for a nonprofit rate — it's an easy way to stretch a tight budget further.

How often should a nonprofit email its supporters?

A consistent rhythm — often a monthly newsletter plus timely campaign and thank-you emails — keeps supporters engaged without overwhelming them. The key is leading with impact and stories rather than only asking for money, so people look forward to hearing from you and stay connected to your mission over the long term.

Growing your supporter list the right way

Your email program is only as powerful as the list behind it, so growing your supporter base deliberately matters as much as the emails you send. The foundation is giving people a genuine reason to subscribe — an impact update, a compelling story, a way to be part of your mission — and making it easy to sign up through forms and landing pages, which tools like MailerLite, GetResponse and Sender provide even without a full website. Add a signup form to your website, share your subscribe link on social media, and collect emails (with consent) at every event, fundraiser and volunteer sign-up. Every donor, volunteer and attendee is a potential long-term supporter, so treat list growth as an ongoing habit woven into everything you do. Just as important is keeping the list healthy and compliant: always get proper consent, segment supporters so donors, volunteers and general subscribers get relevant messages, and periodically re-engage or remove people who never open, since a smaller engaged list outperforms a large stale one and protects your deliverability. Never buy lists — it damages your reputation and rarely works. A steadily growing, well-segmented, genuinely opted-in supporter list is the engine of nonprofit email success, and the consistent, story-led communication you send to it is what turns those subscribers into the loyal, recurring donors your mission depends on.

Measuring what works: the metrics that matter

To raise more over time, a nonprofit needs to learn what resonates with its supporters, and your email platform's reporting is where that learning happens. The most useful metrics are simpler than they sound. Open rate tells you whether your subject lines are compelling and whether supporters recognise and want to hear from you; a healthy open rate means your emails are landing and being noticed. Click-through rate shows whether your content and calls to action are motivating people to act — to read a story, watch a video, or head to your donation page. For appeals, the numbers that ultimately matter are conversions and donations: how many people gave, and how much, from a given email. Watching unsubscribe and spam rates helps you avoid emailing too often or off-message, protecting the relationship and your deliverability. Tools like MailerLite, Mailchimp and Constant Contact present these clearly and let you A/B test subject lines and content, so you can experiment and steadily improve. The point isn't to obsess over vanity numbers but to notice patterns: which stories drive the most engagement, which subject lines get opened, what timing works, and which appeals actually raise money. Feeding those lessons back into your next campaigns compounds over time, so a small nonprofit that pays attention to its email data steadily gets better at engaging supporters and raising funds — turning email from guesswork into a reliable, improving channel for your mission.

The bottom line

The best email marketing software for small nonprofits engages supporters and raises more without straining a tight budget. Choose MailerLite for value, Brevo or Sender for email-plus-SMS on a budget, Constant Contact for support, Mailchimp as a familiar all-rounder, or GetResponse for landing pages and webinars. Lead with impact, automate your thank-yous, and turn subscribers into recurring donors.
