A/B testing (sometimes called split testing) is sending and comparing two versions of an email campaign to see which one performs better. You compare two email sends by creating two or more variants (let’s call them A and B) and then send each one to a sample portion of your list at the same time. The one that gets a better conversion rate (either clicks or opens), wins!
Click Create a New Campaign and build your campaign if you haven’t already. You will set up your A/B split on the third step of the campaign builder, Settings. If you already have an email created, click EDIT under the campaign name, then click Next Step until you get to step 3, Settings:
Once you click on Add A/B Variation, you will see this page:
This is where you will control all your A/B test variants.
Variation: The default is two variants. To add another variation, click Add Variation or Actions > Duplicate to make a new copy of a specific variation.
Weight: This percentage will automatically update as you add or remove variants.
List Sample: The slider lets you choose the percentage of your total list that you want the variants to go to. So if your total list size is 100 emails, and the slider is at 20%, the sample send size to determine the winner would be 20 emails total. If you have two variants, 10 would get Variation A, 10 would get Varation B.
Timer: This lets you choose how much time you want the sample to collect information until we pick the winner.
Choosing a Winner: the winning variant can be determined either by unique opens (open rate) or unique clicks.
Edit Variation: Click here to return to the variant email campaign to make changes.
Preview: Preview the email campaign.
Actions: You can Duplicate or Delete a variant using this menu.
Edit Variation: This button lets you edit the Subject Line and/or From Name. You can also click Edit Content from here to go back and edit the design:
Delete variants until you only have one left.
Navigate to the final Test & Send page for the campaign:
You can use the dark grey Send Test Email button to send one test email of each separately, or use the lighter grey Send Test Emails button to send one of each version simultaneously.
