Testing Email Campaigns with A/B Methodology

Modified on Fri, 13 Sep at 7:25 AM

The A/B testing feature allows marketers to experiment with up to six distinct versions of an email campaign to determine which resonates most with the target audience. Professionals often use this technique to maintain audience engagement and encourage them to take the desired actions, such as making a purchase or clicking on a link. By experimenting with various email formats, you gain valuable insights into what type of content or messaging leads to better responses, ultimately driving more conversions.

Important Notes:

  • Each variation needs a minimum of 10 contacts. If you’re testing four different emails, you’ll require at least 40 recipients—10 for each version.

  • This testing method only works when emails are sent immediately or scheduled. It is not available for batch or RSS-based schedules.

  • If no data on opens or clicks is available within the selected time frame, the first version is automatically selected as the winner.


How the A/B Test Process Works


1. Choose an Element to Test: Start by selecting what aspect you want to test, like the email’s subject line or the body content.


2. Set the Number of Variations: You can test up to six different email versions.


3. Define the Test Duration: Set the time period, ranging from 30 minutes to 24 hours, for the test.


4. Choose the Sample Size: Each email version is sent to an equal portion of your test audience.


5. Determine the Winning Metric: Decide whether to judge the winner based on open rates or click rates.


Steps to Create an A/B Test Campaign

Optimizing for Open and Click Rates

  • Email Subject Line: Your subject line is the first thing a recipient sees, so experimenting with its length or personalizing it can significantly impact open rates. A well-crafted subject line can make the difference between your email being opened or ignored.

  • Email Content: You can also test different parts of your email content, such as headlines, article lengths, call-to-action buttons, or media (like images and videos). These elements can influence the action recipients take and help you create more effective email campaigns in the future.

Setting the Test Duration

Choosing the right test duration is critical. Consider how long your audience will take to read and respond to the email. The test phase can last between 30 minutes and 24 hours. Once the duration is set, the results—either open or click rates—will determine the winning variation. If no results are gathered within the timeframe, the first variation will be sent out to the remaining audience by default.

Determining the Number of Variations

The number of variations depends on your testing needs. You can use a slider to adjust the percentage of your audience that receives different variations. Remember, you need a minimum of 10 contacts per variation, so if you’re testing four versions, you’ll need at least 40 recipients in total.

Picking the Winning Criteria

You’ll need to select how the winning variation is determined. Typically, either the open rate or the click rate will serve as the key metric to decide which email performs best.



Testing and Sending the Campaign

Before launching your A/B test, you can preview the campaign to ensure it’s ready. Once you’re satisfied, set the delivery method to either “Send Now” or “Schedule for a Specific Date/Time.” Once your campaign goes live, you’ll be able to monitor the results and view comprehensive reports on each variation's performance.
