Imagine this: It’s a Sunday morning after a long hectic week, and you think today is perfect for a relaxing brunch with your best friend. However, you happen to know for a fact that she spends every Sunday binge-watching Netflix. But you really want that mimosa, so you start drafting up a text message:

Message 1: Hey! Brunch at my place today. Your favorite fish n’ chips await.


Message 2: I miss you so much. Let’s catch up at brunch today!

Which one would capture her attention more, and convince her to ditch her beloved couch? Don’t you wish there were a way to test the most effective messaging ahead of time?

Believe it or not, this is a form of A/B testing

What’s A/B testing you ask?

A/B testing, also known as split testing, is an extremely helpful email marketing strategy that allows you to create and send two versions of your email campaign. Split testing tests an original version (the control) against another version (the variant, or a variation), where only one element has been changed. Both Option A and Option B are aimed at the same desired action with differences in terms of content, subject line, images, and many other elements. A/B testing is a method of conversion optimization strategy.

So, while the purpose of both text messages is to get your friend out to brunch with you, one will be more rewarding, exciting or compelling to her.

Just like that, when you send an email to your subscribers, certain aspects make them more compelling and get the desired attention.

And, why it works

Well, just like what your nonprofit does is unique and diverse, so are your donors, volunteers and the people interested in what you do.

Email marketing is a powerful tool for nonprofits to get more donations, RSVPs, and volunteers and to spread awareness about your cause. But it only works when you are able to really connect with your audience.

With A/B testing, you can really get an understanding of how your subscribers prefer to engage with your emails. Email split testing is an effective way to optimize your email marketing campaigns to get the results you need.

How to get started with A/B testing

The very first thing you need to do is to answer the question, “What elements should I test?”

If you don’t have an answer to that yet or you’re not sure what can be tested, let’s take a look:

The first thing your email receivers see is the subject line, so it goes without saying that this needs to be the most impactful element of your email. Sometimes even though the content within the email is great, a bad subject line will ruin it all.

For example, if you are sending out an email asking for donations, you could take a direct approach and say something like, ‘Make a Difference; Donate Now’ or be indirect yet make an emotional connection with something like, ‘The puppies at the shelter need you’ and include a ‘Donate’ CTA within. Will one of these email subject lines be more impactful? You can test and find out.

Relevant visuals play an important role by supporting the text and also giving a peek into your world. Images in the email of your organization at work will make a better connection with your supporters and can give them the much-needed push to take the desired action.

For example, if you are hosting a petting event at your animal shelter to raise money for supplies and maintenance, you could either put a picture of animals or a picture of your staff working at the shelter. But which one will work? A/B testing can help.

As one of the most important elements within an email, the CTA holds and highlights the whole purpose of an email. What is it that you want your reader to do? Most importantly, what CTA will entice your reader to actually go ahead and take that action?

For example, you are holding an event and send out invites, the CTA can be ‘RSVP’ or something more casual like, ‘I’ll Be There’. Use A/B testing to figure out which one drives more action.

The design is important not just visually engage your subscribers, but also in terms of how easy to read your emails are. Is the font readable? Are the colors appealing? Is the CTA well highlighted? Does the image support the text? Everything makes a difference. Should the CTA be placed at the top of the email or at the end? Should the text be placed horizontally or vertically? Try out different designs, then pick two that stand out and start A/B testing.

While we typically recommend your emails to be short, sweet, and crisp, that’s not really well defined. Sometimes, a longer story may be needed to make the information more meaningful. What will work with your audience? A one-line copy, a short paragraph, or more? Test your email content to find out.

This is really the most tricky of all but also very important. We all have a different style of talking, and so does every brand, but that also means everyone has a different way of perceiving what’s being said. While for some, a ‘Hey you’ greeting works great, others may expect a ‘Good Evening’. What is your brand’s tone, and how does it resonate with your audience? What style of communication works best for your audience? Find out by testing.

Plan your A/B test

Ready to start A/B testing? Make sure to test one thing at a time to make every step rock-solid; especially if you are just starting out with email marketing. Once you have an idea of what resonates most with your audience, make a record of it and use those guidelines for future emails.

Once you have your guidelines, make a plan and a list of answers to these questions:

  • Do I want to run the test with everyone on my contact list or just a few of them?
  • What am I testing?
  • What tools do I have to measure the results of the A/B test?

With Constant Contact, you can not only run great and successful A/B tests but also get a detailed report that will show you accurate results of the split test. You can measure all relevant and important metrics like Open Rates, Conversion Rates, Click-Through Rates, Unsubscribes, and more.

I recommend you never stop testing new ideas. Things are always changing, and so are your supporters’ ways of consuming your emails. Get started by sending out impactful emails backed by effective A/B testing.
