Measuring results
How should I test a B2B email campaign?
Test a clear hypothesis with comparable audiences and one main change at a time. Check targeting, delivery, and reply handling before judging wording. Small samples produce noisy results, so avoid declaring a winner after a few responses. Qualitative feedback from actual buyers can explain more than a minor percentage difference.
How to approach it
- Write down the change and the outcome you expect.
- Keep audience, timing, and measurement definitions comparable.
- Review the full conversation quality before expanding.
To compare two opening questions, keep the offer and audience similar. Changing the niche, subject, sender, and offer simultaneously makes it difficult to know what caused a difference.
