Delivery issues in mail sending

Incident Report for Hoxhunt

Identified

Hoxhunt is currently facing email delivery issues which our technical teams are working to fix.

Normal adaptive phishing training simulations are delayed as the delivery attempt will be re-tried if the delivery is not successful (in these instances our system automatically deletes the errored delivery attempts and user statistics are not affected.)

Customers in Google environments are not affected by this.

Threat forwarding emails are not affected by this as they are sent in the user's context.

Affected flows:
-Incident escalation emails (delivery will be re-tried automatically but some delay might occur)
-Automated technical testing emails (not re-tried)
-Verification code emails for signing in (not re-tried)
-Email verification emails (not re-tried)
-Welcome emails for starting the training (not re-tried for self-onboarding flow via game.hoxhunt.com/begin)
