Scale Tier & Above
A/B testing requires a Scale tier subscription or higher.
A/B testing (also called split testing) lets you send two versions of a campaign to a small portion of your audience, measure which performs better, and automatically send the winner to the rest. This data-driven approach takes the guesswork out of email marketing.
Steps
- Navigate to Marketing > Campaigns and click Create Campaign.
- Choose A/B Test as the campaign type.
- Select what you want to test:
- Subject line: Same email body, different subject lines. This is the most impactful test.
- Content: Same subject line, different email bodies. Test different layouts, CTAs, or messaging.
- Create Variant A and Variant B with your different content.
- Set the test size — the percentage of your audience that receives the test (e.g., 20% gets Variant A, 20% gets Variant B).
- Set the winning metric — open rate (for subject line tests) or click rate (for content tests).
- Set the test duration — how long to wait before picking the winner (typically 2-4 hours).
- Click Send. After the test period, DreamFlow automatically sends the winning variant to the remaining 60% of your audience.
Tip
Test one variable at a time. If you change both the subject line and the email body, you will not know which change drove the difference in performance.
