What A/B tests should I run on discount email campaigns?

A/B Tests to Run on Discount Email Campaigns

Systematic email A/B testing compounds over time - each improvement you discover applies to every future campaign. For discount emails specifically, the highest-impact tests are those that affect both conversion rate and margin simultaneously.

A/B Test Priority Matrix

Test Design Rules

• Test one variable at a time - combined tests can't isolate what caused the difference
• Minimum sample: 1,000 subscribers per variant for statistical validity
• Run the full campaign before declaring a winner - early opens can mislead
• Measure conversion and margin, not just opens and clicks

Highest-Priority Test: Discount Depth

The minimum effective discount test is the highest-ROI email experiment you can run. If 10% converts 90% as well as 15%, you've found 5 margin points across every future campaign. This test alone can improve annual margin by thousands of dollars on a healthy email list. Run it at least annually as customer price sensitivity evolves.
