How to Set Up Subject Line A/B Tests in Marketo

• Create a New Email Program

Begin by creating a new email program within the “Marketing Activities” tab. Choose “Email” as your program type and name it appropriately.

• Set Up the A/B Test

Inside your email program, go to the “A/B Test” tab. Select “Subject Line” as the type of test you want to conduct.

• Create the Test Variants

Enter your primary subject line and then create one or more variations. These variations will be tested to identify which performs best.

• Define the Audience Split

Decide how you want to divide your audience. You can split your audience evenly or customize the segments depending on your testing needs.

• Set the Winning Criteria

Choose the criteria that will determine the winning subject line. This could be based on open rates, click-through rates, or other metrics relevant to your campaign goals.

• Schedule and Launch the Test

Schedule your email campaign. Marketo will send out the different subject line variants to the specified audience segments and monitor the results.

• Analyze the Results

After the test, review the analytics provided by Marketo. Analyze which subject line performed the best based on the winning criteria you set.

Best Practices for Successful Subject Line A/B Testing

• Test One Element at a Time: For accurate results, focus on testing one element at a time, such as the tone, length, or inclusion of emojis in your subject lines.
• Use a Significant Sample Size: Ensure your audience segment is large enough to produce statistically significant results. Small sample sizes may lead to misleading conclusions.
• Consider Timing: Test your subject lines at different times of the day or week to see if timing impacts open rates.
• Avoid Overlapping Audiences: Ensure that the same recipients aren’t receiving multiple test emails to prevent skewed results.
• Track Long-Term Performance: Don’t just look at immediate results. Track how well the winning subject line performs over time in terms of conversions and customer engagement.
• Document Your Findings: Keep a record of what works and what doesn’t. This will help in refining future subject lines and optimizing your email strategy.
