Increase Your Open Rates with A/B Testing

When you're putting together your newsletter in the editor, you can try out different subject lines with just one click to see what really gets people's attention. The subject line is what makes or breaks it. Will your newsletter make it to the inbox or will it end up in the trash?

Have some fun and explore the possibilities. Try out different subject lines – short and sweet versus long and detailed – and see what happens when you mix humor with facts. Test the waters with personalized addresses versus general formulations, and don't be afraid to throw in a few emojis.

The subject line A/B tests run for a period of time that you define. You’ll then automatically or manually get an analysis which subject line performs better. The winning version will then be sent to all the other people on your email list.

A/B testing is a great way to get your messages into people's inboxes in the best possible way, which will really help you to improve your open rates.

Create Automation Workflow with A/B Test

  1. Create your automation workflow and define the trigger and a recipient list.
  2. Just use the "Split" element to split the selected recipient list into two groups. You can choose how you want to split groups—for example, 40% and 60%.
  3. Create two separate emails and add them to your email automation. Your test groups are randomly grouped, and the recipients are unaware that they are part of a test group.
  4. Once you've set the test duration, the system will do the rest! It'll evaluate which version is more successful for you. For example, you can determine the more successful newsletter version based on the open and click rates.
  5. If you're sending a regular newsletter, like a welcome email, you can use the higher-performance version after your test period.

6 Tips for Successful A/B Testing in Email Marketing

Define a Goal

Are you looking to boost your open rate or conversions? Or are you more focused on clicks? Figure out which key figure you want to improve first.

Define Your Test Parameters

The specific goal in mind will determine which variables are relevant and can affect the desired result. Test these two versions against each other.

Test on a Regular Basis

What's successful today might be old news in a year. It's a good idea to repeat your test at set intervals.

Simultaneous Testing

The time of sending out your email can falsify the test result. Therefore, send your two test variants at the same time if possible - unless you want to test the time of sending.

Select a Large Test Group

The test group must be large enough to achieve a representative result. The CleverReach email editor allows you to run an A/B test for the subject line. However, you will need a recipient list of at least 10 people to do this.

Keep an Eye on Your KPIs

And let's not forget the other key figures in email marketing. It's not just about the open, click-through, and conversion rates. It's also worth looking at bounces and unsubscribe rates, which you can improve with an A/B split test.

FAQs on A/B Testing in Email Marketing

What is a Newsletter A/B Test?

An A/B test in email marketing is a way to compare two different versions of a newsletter. To do this, we split the people who get your emails into two groups at random. One group gets one version of the newsletter, and the other group gets a different version.

  • The newsletter differs in only one detail and is otherwise completely identical in content.
  • Test group A gets version A; test group B gets version B.
  • We then use the results from the two groups to see which newsletter version is working better to make your newsletters even better.

What Parameters Do I Need to Test for My Goals?

To get good results from A/B testing, you need to know what you're trying to achieve first. Which key figures should you be focusing on? And which elements of your newsletter are affecting which key figure?
