Automatic email encryption

“June 5 marks the one year anniversary of the published leaks about NSA surveillance, and in this age of increased eavesdropping and data tampering, we are taking a proactive approach to increasing privacy and security for all of our customers,” said Paul Ford, vice president of product and marketing, SendGrid. “As long as the ESP accepts TLS, our TLS Encryption feature will be applied to each email sent using SendGrid to protect every single message from SendGrid to the recipient - regardless of package type.”

Currently, ESPs including Gmail, Yahoo and AOL allow a TLS connection. The TLS protocol authenticates the email receiver’s server and ensures that the content is not captured or modified in transit. However, mail is only encrypted through these ESPs if the sender proactively sends through an outbound TLS connection.

SendGrid is now activating outbound TLS for all mail sent through its servers and will proactively ask the recipient ESP if they support TLS encryption. Every email sent via SendGrid will be sent with this secure TLS encryption - even if it arrived to SendGrid without encryption. There is no requirement for this outbound TLS feature to be switched on, as it is enabled by default.

SendGrid has invested considerable resources to upgrade its entire infrastructure at no cost to its customers, ensuring an automatic, secure encryption connection for every email that passes through its servers.
