MXDeck for Chrome

You’re set. Three steps to start.

  1. Pin the extension. Click the puzzle icon in the Chrome toolbar and pin MXDeck, so you always see the badge.
  2. Add your domains. The settings tab opened next to this one. Paste up to 25 domains, one per line, and press Save and check.
  3. Read the badge. No badge means every domain is healthy. An amber number means domains worth fixing, a red number means something is broken. Click the icon for the details.

A SPF, DKIM, DMARC enforcing, valid TLS, not listed

B the same, but DMARC is only p=none

C one of SPF, DKIM or DMARC missing

D two missing, or the certificate expires within 14 days

F no MX, an expired certificate, or a blacklist listing

Each problem in the full report comes with the exact DNS record to fix it. You can also check up to 25 domains here or look up MX records any time.
