Email marketing is still one of the best ways for nonprofits to reach supporters, share updates, and get those much-needed donations. In fact, it outperforms all social media platforms by a long shot.

But getting people to actually open your emails? That can be a bit of a challenge. Sadly, many charities lack a proper digital strategy when it comes to email marketing.

This guide goes beyond basic advice, diving into proven, research-backed strategies and technical optimisations to help your emails not only land in inboxes but also compel recipients to click.

Why Open Rates Matter

Open rates reveal how many recipients are engaging with your emails. For nonprofits, the benchmark sits at 20–25%, but why settle for average when there are clear steps to exceed it?

10 Strategies to Boost Email Open Rates

1. Write Subject Lines That Demand Attention

Your subject line is the gateway to your email. Think of it as a personal invitation to open and engage. A strong subject line balances creativity with clarity—enticing enough to pique curiosity but clear enough to convey the email’s purpose.

  • Trigger Emotions: Use subject lines that create a sense of connection, like “See the Impact of Your Support Today” or “You’re Making a Difference—Here’s How.”
  • Ask Questions: Questions naturally invite answers. For example, “What’s Next for Wildlife Conservation?” encourages curiosity.
  • AI Tools: Try subject line analysers to test effectiveness and refine your phrasing.

2. Optimise Deliverability

Deliverability ensures your emails actually reach inboxes instead of being lost in spam filters. Think of it as building a solid foundation before focusing on engagement.

  • Authenticate Emails: Tools like SPF, DKIM, and DMARC protect your emails from being marked as spam. These are like digital passports verifying your email’s legitimacy.
  • Avoid Spam Triggers: Words like “free” or “urgent” can raise red flags. Focus instead on conversational and authentic language.
  • Monitor Reputation: Use tools to check your sender score regularly. Think of it as a credit score for your emails—keeping it high ensures your emails are welcomed, not blocked.

3. Segment Thoughtfully

Imagine receiving an email tailored to your personal interests—it feels more engaging than a generic message. Segmentation achieves this by grouping recipients based on shared characteristics.

  • Interest-Based Segments: Cater to passions. For example, send marine conservation updates to one group and forest preservation news to another.
  • Lifecycle-Based Segments: Acknowledge where people are in their journey with your organisation. New donors may appreciate a warm welcome, while regular supporters value updates on their impact.

4. Personalise Beyond Basics

A simple “Hi [First Name]” is a good start, but personalisation can—and should—go deeper. Tailor your emails based on recipient behaviour, interests, and engagement history.

  • Behavioural Triggers: Set up automated emails for specific actions, like a thank-you message after a donation. It’s like saying “We noticed, and we care.”
  • Dynamic Content: Include content blocks that adapt to the recipient. For instance, showcase their favourite campaign or their recent impact.

5. Design for Mobile and Accessibility

With most emails being read on mobile devices, it’s critical to optimise for small screens. At the same time, inclusive design ensures everyone can engage with your message.

  • Responsive Design: Use email templates that adjust seamlessly to any device, ensuring your emails look polished whether viewed on a phone or desktop.
  • Accessible Features: Add alt text for images, use high-contrast colour schemes, and ensure your text is readable. Accessibility isn’t just good practice—it shows you value all supporters.

6. Incorporate Interactive Features

Interactive emails engage recipients in ways static emails can’t. Adding interactive elements can make opening your email feel like an experience, not a chore.

  • Countdown Timers: Highlight urgency for events or campaign deadlines with live countdowns.
  • Surveys or Polls: Include a one-question survey or poll that users can answer directly within the email. It’s a small but effective way to encourage interaction.

7. Respect Privacy and Build Trust

Today’s users are more privacy-conscious than ever, and respecting their boundaries can go a long way in fostering trust.

  • Transparency: Be clear about why someone is receiving your email. “You’re receiving this because you signed up at our event” builds trust.
  • Offer Choices: Allow recipients to manage preferences, like choosing how often they hear from you. This puts them in control and reduces the risk of unsubscribes.

8. Test and Refine

The best email campaigns evolve over time. Testing lets you refine your approach by understanding what resonates with your audience.

  • A/B Testing: Experiment with variations—subject lines, email layouts, or even call-to-action placement. Over time, you’ll uncover what your audience prefers.
  • Analyse Metrics: Pay attention to open rates, click-through rates, and conversions to identify patterns. Are shorter subject lines performing better? Are images increasing engagement?

9. Maintain a Healthy Email List

An email list is only as strong as its engagement. Regularly managing your list ensures you’re reaching people who genuinely care about your mission.

  • Re-Engagement Campaigns: Before removing inactive recipients, send a re-engagement email. Try something like: “We’ve Missed You! Here’s What’s New at [Your Organisation].”
  • Prune Inactive Addresses: After a final attempt to reconnect, it’s okay to remove unresponsive users. A smaller, engaged audience is more valuable than a large, disinterested one.

10. Optimise Timing with AI

Timing is everything. Research shows that sending emails at optimal times can significantly boost open rates, and AI tools make it easier than ever to get it right.

  • Send-Time Optimisation: Tools that analyse past user behaviour can predict the best time for each recipient. It’s like scheduling emails when your audience is most receptive.
  • Experiment: While many studies suggest mid-morning on weekdays, test to see what works for your audience. The ideal timing can vary based on your nonprofit’s cause and region.

Measuring Success: Advanced Metrics

Understanding your email’s performance involves more than tracking open rates. Here are key metrics to watch:

  1. Click-Through Rates (CTR): Measure how many recipients clicked on links. A strong CTR indicates compelling content.
  2. Conversion Rates: Did recipients complete your desired action, such as donating or signing up for an event? This is the ultimate indicator of success.
  3. Bounce Rates: High bounce rates suggest issues with your email list or sender reputation. Monitor and address these promptly.
  4. Unsubscribe Rates: Spikes in unsubscribes may indicate that your frequency, content, or targeting needs adjustment.

Final Thoughts

Improving email open rates is about more than clever subject lines - it’s a blend of technical know-how, strategic targeting, and creative engagement. By implementing these research-backed strategies, your nonprofit can build stronger connections with supporters and achieve its mission more effectively.
