Email policies and suspension standards

To preserve your reputation as a sender, Dynamics 365 Marketing has developed a deliverability protection system that detects excessive hard bounces, spam reports, block listing, or abuse complaints. This system protects our entire customer base. If email criteria are violated, accounts can be placed under review or terminated.

Stages of review

  • Warned

    In the first stage of review, the Marketing application sends a warning notification to the address associated with your account. The account maintains full sending functionality during the warning period. However, if the application doesn't receive a response or the protection system records successive alerts, your account may be suspended to prevent further risk to your sending reputation.

  • Suspended

    Email sending is suspended when the deliverability protection system detects that one or multiple email limits were breached on your email recipients, or fraudulent account activity was detected.

    When email sending is suspended, you see a warning banner in your email tool about a problem detected by the deliverability protection system. The banner contains details about the problem and recommendations to improve future email messages.

    If your email sending is suspended, create a ticket with our Email Deliverability team. When we believe that you have taken sufficient steps to address the cause of suspension, we will reinstate your account.
