The MTA-STS DNS TXT record indicates that you expect emails that you send are properly encrypted. It can be deployed in test mode to gather feedback before you enable it.
The SMTP TLS Reporting (TLS-RPT) DNS TXT record then requests that receiving mail servers provide us with feedback on how frequently encryption is used.
From your dashboard you can quickly see any gaps in your email encryption and identify problems that need to be resolved.
In the age of GDPR, CCPA, and other privacy focused regulation, sending emails without encrypting them seems unthinkable.
With SMTP TLS Reports you can be sure that all of the emails you send are properly encrypted and protected when sent across the Internet.
