DKIM Record Checker

Check whether a domain publishes a DKIM key — we scan the common selectors for you. DKIM signs your mail so it’s trusted; but even perfect DKIM won’t save you if you send to dead inboxes.

We scan common selectors (google, selector1, selector2, s1, s2, …). DKIM authenticates your sending; Engage makes sure your recipients are real — only verified, deliverable addresses — so your signed mail actually reaches people and your reputation stays clean.
