SPF, DKIM and DMARC checker

Check SPF, DKIM and DMARC for every domain in one table, with a blacklist check for the server’s sending IP next to it. When a record is missing, the exact TXT line to add is waiting beside it, ready for the DNS zone. Add it and the row turns green on its own.

03 / What it does5 points

What it does.

When a domain’s email lands in spam or isn’t delivered at all, the cause is rarely the server. It is usually a missing SPF, DKIM or DMARC record. The table tells you which one is missing and hands you the exact TXT line, and the status turns green by itself once you add it to the zone. The blacklist check sits on the same page, so you don’t need a third-party lookup tool to see whether the server’s IP is listed.

  1. Each domain shows the state of all three records: present, missing or broken.

  2. Missing records are read from the DNS zone itself, so this screen and the DNS editor never disagree.

  3. A blacklist check shows the server’s sending reputation.

  4. The domain picker is shared across three tabs: you stay on the same domain in the mail queue, the mailboxes and here.

  5. DKIM signing is switched on or off from the sending policy screen.
