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.

Email deliverability checklist FAQ

Deliverability is whether the mail you send actually reaches the inbox - not the spam folder, and not blocked outright. It's decided by mailbox providers (Gmail, Yahoo, Outlook) based on how you authenticate, how clean your list is, how often people complain, and your sending reputation over time. This checklist covers the fundamentals every one of those providers looks at.

No - nothing can. The checklist covers the technical setup and list-hygiene groundwork that mailbox providers reward, and skipping any of it will actively hurt you. But inbox placement also depends on the content you send and how recipients engage with it. Think of a full checklist as the price of entry, not a guarantee.

Their 2024 bulk-sender rules make a handful non-negotiable: authenticate with SPF, DKIM and a DMARC policy; offer one-click unsubscribe and honor opt-outs within two days; keep your spam-complaint rate under 0.3%; and send over TLS. Miss these and bulk mail to those providers gets throttled or rejected. See the sender-requirements guide linked on each item.

No - the checklist runs entirely in your browser and nothing is sent to a server, so progress isn't stored and resets if you reload the page. It's designed as a quick self-audit you run against your own setup, not a saved account. Treat the linked guides as the reference for anything you can't tick off yet.
