Will your email reach the inbox? Enter the domain you send from and paste a draft. You get a score for your authentication records and one for your wording, and a short list of what to fix first. Connect your own mailbox over SMTP for a real inbox placement test. Nothing is stored.
What this can and cannot tell you
It reads your public DNS records and scores the wording of one email. It cannot see inside anyone's inbox, so the score is an estimate and not a guarantee. The placement test shows where one message landed in the inboxes you connect. It does not measure your bounce or complaint rate, which depend on who you send to and how. Google Postmaster Tools (postmaster.google.com) shows Gmail's own view once you send a few hundred a day.
DKIM can only be tried on common key names, so a warning there may just mean yours has another name. The surest check: send yourself an email at Gmail and use Show original; you want SPF, DKIM and DMARC all to say PASS. For general information only; not legal or compliance advice.

Our Email Setup Check ($69) is a written list of the exact records to add or fix for your domain, with one re-check afterward. It uses public DNS records only, so we never need a login.
