Email deliverability checklist.
Audit your setup against the fundamentals mailbox providers reward — authentication, sender requirements, list quality and reputation. Tick off what you've done and watch your score climb. Every item links to a guide for the rest. Runs right here in your browser.
Authentication
Sender requirements
List quality
Reputation
Ticking every box is the technical and hygiene groundwork for the inbox — it doesn't override poor content or low engagement, but you can't get there without it. Nothing here leaves your browser.
Why this checklist is in this order
Deliverability stacks: authentication proves who you are, the Gmail and Yahoo sender requirements set the baseline every bulk sender must meet, and list quality plus a steady sender reputation are what keep you in the inbox once you're there. The single biggest lever most senders are missing is list hygiene — dead and invalid addresses drive the hard bounces and spam-trap hits that quietly wreck a reputation. Start with cleaning your list, then work down the rest.
