# Enable A/B Testing for an Email

You can enable A/B testing for any Account Engagement classic email. After A/B testing is enabled, you can switch between the two versions to edit your content. A/B testing begins only after you schedule or send your email.

Important We recommend that you test only one variable at a time. When you have more than one difference between the two versions, it’s difficult to determine what made the winner effective.

1. Open a draft email.
2. On the Building tab, click **Basic Info**.
3. Select **Enable A/B Testing**.
4. Use the A and B tabs to switch between the two versions of your email and make changes.
    
    If you’re testing two subject lines or different reply-to addresses, keep the content of the two versions the same and move to the Sending tab.
5. On the Sending tab, configure your send settings.
    1. Select your recipient and suppression lists.
    2. Select a sender and a custom reply-to address for each version.
    3. Enter a subject line for each version.
    4. Set a duration for your A/B test, select engagement criteria, and choose the percentage of your audience that you want to test.
    5. Add completion actions for your email. Completion actions apply to version A, version B, and the winning version of the email.
    6. Schedule your test, or click **Send Now** to begin the test immediately. The winning email is sent when the test period ends.

After you schedule or send an A/B test email, it appears on the A/B Tests tab.
