Split Tests

Manage advanced split testing by comparing multiple variations of your email campaigns. This feature ensures optimal performance by automatically analyzing and selecting the best-performing variations for your audience.

Overview​

Split tests (A/B testing) allow you to compare different broadcast variations to determine which performs best. The system automatically analyzes results and can select the winning version for the remaining audience.

How Split Tests Work​

  1. Create a Split Test - Define which broadcasts to compare and winning criteria
  2. Schedule the Campaign - Use Actions → Schedule with Campaign Type "Split Test"
  3. System sends variations - Broadcasts are sent to equal portions of the audience
  4. Winner is determined - Based on open rate or click-through rate
  5. Action is performed - Update results or send winner to remaining audience

Based on Broadcast Performance​

Split tests compare the performance of different broadcasts to find the best performer.

Campaigns (Broadcasts to Compare)​

Select two or more broadcasts to compare:

  • Broadcasts are displayed in a hierarchical checkbox list grouped by broadcast group
  • Check the broadcasts you want to include in the test
  • Each selected broadcast becomes a test variation
  • Emails will be distributed equally among selected broadcasts

Example: Select "additional field" and "campaign with click" to compare these two broadcasts.

Decision Percentage Winning Criteria​

Enter the percentage of the audience to use for testing (e.g., 100).

Best Practices​

Test Design​

  • One variable at a time - Isolate what you're testing for clear results
  • Clear hypothesis - Know what you expect and why
  • Sufficient sample size - Ensure enough recipients for statistical significance
  • Equal distribution - Let the system split audience evenly

Timing​

  • Allow adequate duration - Don't rush winner determination
  • Consider time zones - Account for when recipients open emails
  • Weekday vs. weekend - Engagement patterns differ

Analysis​

  • Document learnings - Record what worked and why
  • Apply insights - Use winning approaches in future campaigns
  • Continue testing - Always look for optimization opportunities
  • Build best practices - Create guidelines based on test results

Troubleshooting​

Not Enough Data​

Cause: Sample size too small or duration too short.

Solution:

  • Increase test percentage
  • Extend wait duration
  • Use larger contact lists

Inconclusive Results​

Cause: Variations performed similarly.

Solution:

  • Test more dramatic differences
  • Increase sample size
  • Consider external factors affecting results

Winner Not Determined​

Cause: Duration hasn't elapsed or processing issue.

Solution:

  • Verify duration settings
  • Check that wait time has passed
  • Review campaign status in Scheduled Campaigns

Split Test Not Appearing in Schedule​

Cause: Split test not saved or inactive.

Solution:

  • Verify split test was saved successfully
  • Check split test exists in Campaigns → Split Tests
  • Create new split test if needed
