Stop guessing why your emails miss the inbox

A practical, step-by-step deliverability checklist for marketers and solo founders who already send — and need a repeatable pre-flight process.

Auth → list hygiene → content → test → monitor. One pack. No fluff webinars. Built for UK senders who prefer clear checkboxes over hype.

Who this is for

Who should skip it

What you get

  1. The checklist — substantial, ordered, usable the same day
  2. Sections covering: domain & DNS auth, list & consent, content & headers, infrastructure signals, pre-send testing, post-send monitoring, incident response
  3. Placeholder rows for your ESP, domains, and tool stack so you can customise
  4. Clear “stop and fix before you continue” gates so juniors do not skip auth

No invented guarantees (“inbox forever”). Deliverability is probabilistic; process reduces avoidable failures.
