With DMARC aggregate reports data in place, you can monitor the sender reputation of all your outbound IP addresses, no matter it's your own email server, or 3rd-party email delivery services like Mailchimp and Mailgun.

This gives you an opportunity to take action to rectify the issue in case one of your outbound IP address is blacklisted by any of:

  • Spamhaus ZEN
  • SpamCop Blocking List
  • Barracuda Reputation Block List
  • Passive Spam Block List
