Campaign testing is a structured process for validating templates, links, deliverability posture, and inbox outcomes before production sends.

Quick answer

A campaign test should answer four questions:

  1. Does the email render correctly across key clients?
  2. Are links, tracking, and fallback paths valid?
  3. Is deliverability risk acceptable for launch?
  4. Can the team reproduce and triage failures quickly?

3) Inbox and placement checks

4) Decision and rollback criteria

  • Define blocking conditions before launch
