Email health monitoring

A DNS change made by a web developer, a new email tool or a domain move can quietly break your email authentication. We check it every week and tell you in plain English when something changes.

  • Checks that your SPF record is valid and ends with -all or ~all
  • Tracks your DMARC policy and helps you move from p=none to reject
  • Finds DKIM on common selectors
  • Alerts you by email as soon as a record changes or breaks
