A/B subject lines
Find out which subject line actually earns replies, not which one you like.
What it does
Every step can have an optional Subject B. Prospects are split between variant A and B, and analytics show results per variant.
How it works
- Fill in "Subject B (optional A/B)" on a step.
- Each enrollment is assigned variant A or B.
- Compare reply rates per variant on the Analytics page and export to CSV.
Tips
- Test one idea at a time, for example a question versus a statement.
- Wait for at least a few dozen sends per variant before drawing conclusions.
