Check your domain’s email authentication

Check your domain for possible issues with DMARC, SPF and DKIM records. Use the IOS Domain Scanner below as a starting point for understanding your domain’s email authentication setup.

How to use the domain scanner

  1. Enter the domain you want to check, for example example.com.
  2. Select Scan Now in the tool above.
  3. Review the checks and any issues highlighted by the scanner.

What can the results tell you?

The embedded tool checks for possible issues with DMARC, SPF, DKIM and BIMI records. Use the findings as an initial view of your email authentication setup and a starting point for further investigation.

A domain scan is not a complete security audit and does not guarantee email delivery or protection against every form of impersonation.
