Improved Detection of Accept-All Addresses

Mailgun’s Email Validations now provide a deeper view into the risk profile of your email lists with the following: 

• Accept-All Identification: Validate can now reliably detect when an email domain is configured as accept-all. These domains always return a “valid” response but, unlike catch-all, may result in a delayed bounce. 

• High-Risk Flagging: If an accept-all address shows no historical engagement data (no opens, clicks, or prior sending activity), Mailgun now flags it as High Risk.
