A/B Testing Guide

Christy Cook Updated by Christy Cook

A/B testing (also known as split testing) is a process of showing two or more variants of the same email to different segments of customers at the same time and comparing which variant drives more conversions.

When to use A/B testing

You can use A/B testing for anything from testing subject lines, call-to-action buttons, link placement or content. A/B testing is a great way to increase the open and click-through rates of your marketing, and even decrease opt-outs.

How it works

  • Select an email or text message to test.
  • Choose the number of variants to test.
  • Configure how they're sent and measured.
  • Schedule the emails or text messages to be sent.
  • Once the test has concluded and the winning version has been found, the system will automatically send the winning version to the rest of your list.

Examples of what to test

You can test many almost any aspect of your marketing pieces to improve results, but here are a few ideas to help you get started:

  • Subject lines - your customer's first impression of what's inside.
  • Length - how much content do your customers prefer? Research shows 60-70 characters is optimal.
  • Word order - the order in which you place your words in the subject line or preview text matters.
  • Personalization - using your customer's first name, etc.
  • Visuals - the use and placement of images, icons and emojis.
  • Call-to-action links - buttons or text, placement, wording, size and coloring.

Tips for effective testing

  1. Decide what your "success metric" is; do you care more about opens or clicks?
  2. Test only one variable at a time - have a basic hypothesis you are trying to prove out.
  3. Test your variants at the same time.
  4. Don't make any mid-test changes.
  5. Document your results so you can build on what you learn.
Remember, the ultimate goal is conversions!
