Following email best practices is an important prerequisite for good and sustainable deliverability. Check your email against all known standards and get a detailed report with results and suggestions.

What do we check?

We currently look at the following aspects of the email:

  • Server configuration
  • SMTP envelope
  • SPF authentication
  • Mail header fields
  • DKIM authentication
  • DMARC compliance

Each aspect contains a number of checks. The results are very detailed and show the source of a problem. No guesswork is needed to fix issues!
