Split or A/B Testing in Email Campaigns

Overview

A/B Testing (split testing) helps you make data-driven email decisions by testing multiple versions of a campaign and selecting the winner based on performance.

• Test up to 6 variations of an email.
• Run tests on subject lines or email content.
• Select a winner using Unique Open Rate or Unique Click Rate.
• Automatically send the winning version to the remaining audience when the test ends.

How to Set Up A/B Testing

1. Go to Marketing → Emails and open Email Campaigns (or Campaigns).
2. Create a new campaign and click the A/B Testing tab.
3. Enable the A/B testing toggle.
4. Choose what to test: Subject Line or Email Content.
5. Set the Test Duration.
6. Select the number of variations (up to 6).
7. Set the test size distribution and add your variations (manually or with AI tools if available).
8. Select the Winning Criteria: Unique Open Rate or Unique Click Rate.
9. Choose how to deliver: Send Now or Schedule.

Managing Tests

During an A/B test, you can manage the campaign like any other—pause, edit, and resume when needed (depending on send status and platform rules).

• When the test duration ends, BizStackPro selects a winner automatically.
• The winning version is sent to the remaining contacts based on your criteria.
• Review results to guide future subject lines, layouts, and calls-to-action.

Use Case Example

Launching a new product and unsure which subject line will get the most opens? Run a subject line A/B test with a portion of your list, then automatically send the winning version to everyone else.

Why This Matters

• Better engagement: You’re not guessing—your audience tells you what works.
• Higher performance: Winning versions can improve open and click rates.
• Repeatable learning: Each test gives you insights you can reuse.
• Smarter scaling: Send your best message to the largest portion of your list.
