25 Best Nonprofit Email Marketing Tips to Win Your Whole-Year-Round Giving Season

Look, we’re all a little tired of treating email like it’s only for December panic mode, right? Here’s the thing: email marketing has quietly become the workhorse of nonprofit fundraising, delivering an average ROI of 4200% (yep, that’s $42 back for every dollar spent) (Funraise). But the real challenge isn’t just sending emails. It’s building a year-round giving culture that keeps your supporters engaged when it’s not Giving Tuesday.

In this guide, we’ve rounded up 25 practical tips to help you transform your email strategy from sporadic appeals into a retention powerhouse. We’ll cover everything from list-building and content that actually connects, to automation that saves you hours and testing strategies that boost results.

Build and Clean Your List (Tips 1-5)

Your email list is only as valuable as its quality. So let’s talk about growing it strategically while keeping it healthy.

Tip 1: Add sign-up forms everywhere. We’re talking website pop-ups, donation confirmation pages, event registrations, social media profiles—anywhere someone might be thinking, “Yeah, I want to hear more from these folks.” Peer-to-peer campaigns and social ads work wonders for rapid list expansion too.

Tip 2: Offer lead magnets that people actually want. Downloadable impact reports, volunteer guides, exclusive PDFs—give visitors something valuable in exchange for their email address. It turns casual browsers into committed subscribers.

Tip 3: Segment ruthlessly. One-time donors shouldn’t get the same emails as your five-year monthly givers. Welcome series for newbies, milestone celebrations for loyalists, opportunity alerts for volunteers—segmentation is where relevance lives.

Tip 4: Clean quarterly. Surprising stat: only 38% of nonprofits regularly remove subscribers who haven’t opened emails in six months (Social Impact Fundraising). But keeping ghost contacts tanks your metrics and deliverability.

Tip 5: Re-engage lapsed subscribers before you say goodbye. Try polls, impact stories, or (okay, we’re not above this) adorable pet photos. Give them one last chance to remember why they signed up in the first place.

Here’s some context: the average nonprofit manages about 4,191 contacts, though smaller organizations typically have around 547 (Social Impact Fundraising). Growth slowed to just 4% in 2024, so proactive list-building isn’t optional anymore—it offsets natural churn and keeps your pipeline flowing.

Protip: Platforms with real-time segmentation (like Funraise) mean you’re not spending hours manually syncing lists or juggling multiple tools. Your lists stay fresh, and your campaigns stay relevant without the headache.

Craft Compelling Content (Tips 6-10)

Content is where donor relationships actually deepen. Generic appeals just don’t cut it when you’re competing with 100 other emails in someone’s inbox.

Tip 6: Write like you’re talking to a friend. Imagine you’re grabbing coffee together, not drafting a formal appeal letter. This humanizes your mission and builds authentic connections instead of transactional ones.

Tip 7: Share success stories with photos, not just asks. Show your supporters exactly how their previous gifts made a difference: “Your gift fed 50 families last month.” Plus, educate them on ongoing challenges—it positions your organization as a thought leader, not just a donation collector.

Tip 8: Thank promptly. Send post-donation emails within 24 hours detailing how their funds will be used. It reinforces giving behavior and sets the stage for future engagement. And honestly? Automation makes this ridiculously easy.

Tip 9: Balance your value. Mix program updates, volunteer opportunities, advocacy calls-to-action, and yes, occasional donation appeals. This prevents donor fatigue and keeps people engaged year-round instead of just when you need money.

Tip 10: Use high-quality images that create emotional connections. Show faces, not logos. Emotive visuals of the people you serve consistently outperform text-only emails because they foster the kind of emotional investment that sustains giving beyond single transactions.

Common Challenges We See Daily

Before nonprofits switch to integrated platforms (or even while getting started), we witness some pretty predictable struggles. You might recognize a few.

The scattered tool syndrome. Marketing on Mailchimp, donations on another platform, CRM somewhere else entirely. One client we worked with spent eight hours monthly reconciling lists across three platforms. That’s a full workday just playing data matchmaker.

The thank-you gap. Donors give, then hear crickets for months until the next emergency ask. This silence absolutely kills retention. We’ve seen organizations with 40% open rates drop to single digits because they only emailed when they needed something.

The personalization paralysis. Teams know they should personalize, but donor data lives in disconnected silos. So they end up sending “Dear Friend” emails to five-year recurring donors. Ouch.

These aren’t unique failures, by the way. They’re systemic issues plaguing small-team nonprofits everywhere. The solution lies in integrated platforms that eliminate friction between what donors do and how you respond.

Design and Optimize Emails (Tips 11-15)

Strategic design turns opens into clicks and clicks into actual conversions. Here’s what we’ve found works:

Element	Best Practice	Impact
Subject Lines	4-15 words, personalized (e.g., “[Name], your impact last year”), questions or urgency	Boosts opens by 26% (WildApricot)
Mobile Optimization	Responsive templates, large CTAs	50%+ opens happen on mobile (Funraise)
Layout	Short paragraphs (2-3 lines), white space, 1-3 brand colors, bold CTAs	Improves readability and click-through rates
Personalization	Merge tags for names, past gift amounts, dynamic content blocks	Significantly increases engagement (KWSM Digital)
Footer	Clear unsubscribe link, contact info, social media links	Builds trust and ensures compliance

Tip 11: Test subject lines via A/B testing. Try “Join Us” versus “Your Help Needed Today” to refine what actually drives opens. Nonprofit average open rates hover around 28.59%, so there’s room to play (Social Impact Fundraising).

Tip 12: Include one clear CTA per email. A bold “Donate Now” button linking directly to your donation form works best. Don’t make people hunt for what you want them to do.

Tip 13: Brand consistently. Use your logo, colors, and voice across every email for instant recognition. Your supporters should know it’s you before they even read the sender name.

Tip 14: Comply always. Respect GDPR, CCPA, and CAN-SPAM regulations with easy unsubscribe options. It’s not just legal—it’s respectful.

Tip 15: Track KPIs religiously. Monitor open rates, clicks (nonprofit average: 3.29%), and conversions using integrated tools (Social Impact Fundraising). You can’t improve what you don’t measure.

Protip: While standalone AI tools help, daily workflow efficiency comes from platforms like Funraise that have AI components built directly into your workspace. Generating email copy, subject line suggestions, and donor insights without leaving your fundraising dashboard makes a huge difference because it has your full operational context.

Automation and Year-Round Nurturing (Tips 16-20)

Automation transforms sporadic campaigns into consistent relationship-building engines. And honestly? It’s a lifesaver for small teams.

Tip 16: Set welcome drip series for new subscribers. Here’s why: 74% of supporters expect them, and they generate 202% higher open rates than standard emails (Social Impact Fundraising). That’s not a typo.

Tip 17: Trigger milestone celebrations. Automate “1-year donor anniversary” emails or “You’ve donated $500 total!” messages. These personalized touches dramatically improve retention because people love being recognized.

Tip 18: Schedule consistent sends. Whether it’s weekly updates or monthly newsletters, regularity keeps your mission top-of-mind without overwhelming inboxes. Fun fact: 62 emails per year is now the nonprofit average, up 9% (Social Impact Fundraising).

Tip 19: Leverage seasonal moments beyond the obvious. Sure, holidays and Giving Tuesday are important, but sustain engagement with off-peak volunteer opportunities, behind-the-scenes content, and educational resources when everyone else goes quiet.

Tip 20: Survey supporters quarterly for communication preferences and interests. Use their feedback to tailor future content and demonstrate you actually value their input, not just their wallets.

Automated workflows are particularly powerful for abandoned donation recovery, expired credit card alerts, and re-engagement campaigns. And when they’re seamlessly integrated? You’re not manually triggering anything or wondering if it sent.

“The organizations that thrive are those that view fundraising as relationship-building, not just transaction-processing. Every email is an opportunity to deepen connection.”

Funraise CEO Justin Wheeler

Protip: Email drives $58 per 1,000 fundraising sends (Neon One). Automated nurture sequences maximize this ROI by reaching donors at optimal moments without you lifting a finger.

Advanced Testing and Experimentation (Tips 21-25)

The final five tips push beyond basics into strategic experimentation territory.

Tip 21: A/B test everything. Subject lines, send times, CTA button colors, ask amounts. Try suggesting specific upgrade amounts for loyal donor segments to increase average gifts. You’d be surprised what a $5 difference in suggested giving can do.

Tip 22: Ask sooner post-gift. Research shows reaching out 1-3 weeks after an initial donation (versus waiting months) helps establish recurring giving habits. Strike while the warm fuzzies are still fresh.

Tip 23: Offer multi-engagement options. Include donate, volunteer, and social share CTAs in single emails. Not everyone can give financially right now, but everyone can participate somehow.

Tip 24: Integrate social media links. Encourage email subscribers to follow and share your mission across platforms, amplifying reach year-round. It’s free marketing, people.

Tip 25: Use AI for content previews. 81% of nonprofits now use AI tools, with 85% reporting better content quality (Social Impact Fundraising). Preview how emails render across devices before sending to avoid embarrassing formatting disasters.

Unconventional experiment: Try doubling your send frequency for one month. From monthly to bi-weekly, for example. It sounds counterintuitive (won’t people unsubscribe?!), but data shows this often warms audiences for year-round giving without increasing unsubscribe rates. The key is ensuring every email delivers genuine value, not just noise.

Making It Work Year-Round

The shift from seasonal to year-round giving starts with treating email as relationship infrastructure, not just an ask channel. New donor retention averages around 20%, but organizations using sophisticated email nurturing see significantly higher rates (Funraise). That’s not magic—it’s strategy.

The beauty of integrated platforms is that your donation data, email campaigns, and donor insights live in one place. No more exporting CSV files at midnight or wondering if your thank-you email actually sent. Real-time segmentation means donors receive relevant messages based on their latest actions, not outdated lists you downloaded three weeks ago.

Start with the fundamentals: clean your list, segment thoughtfully, automate gratitude. Then experiment with frequency, content types, and personalization depth. Track what works using built-in analytics, and remember that consistency beats perfection every single time.

Nonprofits now send an average of 62 emails per subscriber annually (Social Impact Fundraising). That’s not inbox spam when done right—it’s strategic nurturing that inspires 33% of donors most and drives 11% of online revenue (Neon One). But you’ve gotta have the right tools and approach to make it sustainable for your small team.

Funraise offers integrated tools that reclaim hours currently lost to manual processes—time you could spend actually building donor relationships that last all year long. Plus, there’s a free tier perfect for testing these strategies with zero commitment, and premium features that scale as you grow.
