Mailings :: A/B Testing

Use ReachMail’s A/B Testing to find the best-performing email. Test subject lines or content on a small portion, then send the winner to your full list.

Overview

The A/B Testing feature is a simple and fast way to test different mailings on a portion of your list before sending to everyone. You can see the performance (open rate, click-through rate, etc.) and then decide which mailing is the best - and then send that one to the rest of the list. You can use this feature to check if a different subject line would help or to see if a different creative, colors, etc. would be better. Test two or more versions head-to-head or just one message on it’s own to make sure it performs up to expectations before you send it.

How To

After selecting your mailings for A/B testing, you’ll be taken to the scheduling page where you can define how much of your audience will be used for the test. A slider will appear on the right side, allowing you to choose the percentage of your list that will receive the test messages.

• On the Schedule Mailing page, locate the slider on the right
• Adjust the slider to select the test percentage of your list
• The selected portion will receive the A/B test messages

We recommend waiting 24 hours before reviewing results to get an accurate comparison of your A/B test performance. You can then review detailed reports to determine which mailing performed best and send it to the rest of your list.

• Go to the Reports tab
• Select Individual Mailings
• Choose the messages you tested
• Run the report to compare performance side by side
• Select the best-performing mailing
• In the Schedule Remainder section, click Send Now to complete the campaign

If you need a deeper analysis of your A/B test results, you can access detailed reporting for each mailing. This allows you to explore specific engagement metrics and take further actions based on recipient behavior.

• Click the Details section in your report
• View in-depth metrics and performance data
• Use available options to:
  • Download opens, openers, or opt-outs
  • Review bounce data
  • Copy openers to a list for follow-up campaigns

Note: The mailings should differ in some way. You may want to change subject lines, use a second domain, or maybe try out different content to gauge user response.
