Writing a Compelling Fundraising Email Series
Last updated: June 26, 2025
While we don’t advise directly on email design and content, we pulled together a few best practice recommendations specific to fundraising emails to help Switchboard users get started.
The following tips are suggestions -- it's always a good idea to test to find out what works best for your program!
Crafting Your Initial Fundraising Email
Make sure your Call to Action (CTA) adds clear value.
To help you do so, think about answering the following questions in your email copy:
How will this fund help solve the problem you’re talking about?
Why does your audience have to donate now?
Use your fundraising page to double down on your impact.
If you’re talking about a new topic, try creating an fundraising page about that specific issue, with language that brings home why they should donate
[ActBlue-specific] Be sure you’ve added your refcodes.
Refcodes will help you track which link is generating donations
You can see the refcode in the URL of the ActBlue link. For more on setting up refcodes, see this page from our friends at ActBlue.
Each email program chooses to set up refcodes differently. There are no rules as to how you set up your nomenclature. We just recommend that you create a convention and stick to it across all sends.
If you have an ActBlue webhook setup, you can easily track donations on Switchboard. We also provide a robust fundraising analytics dashboard in-tool for free!
[ActBlue-specific] Try splitting your audience into high and low dollar donors.
Try testing higher donation asks for high dollar donors, since they’ve shown a higher capacity and willingness to give.
Use different refcodes for each email so you can see how much of the total is donated by high-dollar vs low-dollar donors.
[ActBlue-specific] Try using ActBlue express lane links or buttons so people can select how much they’d like to give within your email
You can generate ActBlue express lane buttons within your ActBlue account (not on Switchboard). Be sure to include the ActBlue disclaimer language included with those buttons.
Best practice dictates keeping the first few sentences above your CTA short and to-the-point. This space is often called “above the fold”. The average person only spends 7-8 seconds reading an email, so it’s best to get to the crux of your argument rather quickly.
When creating your “above the fold” content, here are some questions to consider:
Why should they take your action NOW?
How will this action help this campaign?
Why do they care about helping this campaign?
Try setting a fundraising deadline or goal you’re trying to hit. Switchboard’s visual editor even has an easily embeddable countdown clock you can customize to fit your brand.
Try explaining where the money is going to go, and why. In other words: why should they donate to your candidate instead of another one who emailed them recently?
Subsequent Fundraising Emails
If you included a deadline or fundraising goal, you probably won’t achieve that goal from a single email. As a result, many programs will follow-up with 2-3 emails (3+ days after the previous email), letting their audience know how close they are to the goal or remind them of the time limit.
To improve donor relationships, some programs will remove donors who give to their fund from these subsequent emails – this can protect the donors from churning and build goodwill.
When sending these follow-up emails, many programs choose to dive deeper in a particular topic or approach the topic from a different angle.
Many campaigns send a thank-you note to all their supporters when they hit the goal.
When you’re sending these emails, avoid subject lines that contain terms like “fwd:” or “re:” as they have been known to trigger spam filters.
