What is a Good Email Open Rate for UK Non-Profits? (And How to Fix Yours)

When it comes to building lasting donor relationships, email marketing is easily one of your most powerful digital tools. Social media algorithms can change overnight, but your email list is a direct, unfiltered line straight to the people who love your cause.

But what happens if you spend hours typing up your monthly update, only to notice that hardly anyone is actually opening it?

Let's look at the UK benchmark statistics for the charity sector, and explore exactly how you can fix low engagement.

The Benchmark: What is a "Good" Email Open Rate?

According to recent industry data across major email platforms like Mailchimp and Brevo, the average email open rate for the non-profit sector sits around 25% to 28%.

If your open rates are consistently sitting below 20%, it means your emails are either getting caught in spam filters, your subject lines aren't grabbing attention, or your subscriber list needs a serious clean.

Here are 4 simple ways to boost your numbers and get your newsletters read.

1. Write Hook-Driven Subject Lines

Your subject line is the single most important factor determining whether your email gets opened or deleted. Avoid boring, repetitive titles like "Kindly Charity November Newsletter." Instead, use curiosity, urgency, or emotion:

• Avoid: "Our latest charity update."

• Try: "Because of you, Sarah has a safe place to sleep tonight."

• Try: "We have 48 hours left to reach our goal...

• 
  

2. Optimise Your "Preview Text"

The preview text is the snippet of text that appears right next to or underneath your subject line in a modern inbox. If you don't customise this, it will automatically pull in random text from the very top of your email, like "Can't see this email? View in browser."

Instead, use this space as an extension of your subject line to build intrigue (e.g., "Open to see the incredible impact your support made this month").

3. Personalise and Segment Your Lists

Your regular financial donors, your occasional event volunteers, and your corporate partners shouldn't all receive the exact same email. Group your list into distinct segments based on subscriber behaviour. When you speak directly to someone's specific relationship with your charity (e.g., starting an email with "As a valued volunteer..."), your engagement metrics naturally skyrocket.

4. Clean Your List Regularly (The Hard Truth)

It sounds counterintuitive, but having a smaller email list can actually improve your marketing results. If you have hundreds of contacts who haven't opened an email from you in over a year, they are dragging down your overall domain reputation. Email providers like Gmail and Outlook will notice this and start routing your emails directly to the "Promotions" or "Spam" folder.

Once a year, send a final "Do you still want to hear from us?" email to inactive subscribers, and safely delete those who don't opt back in.
