Protocol and Encryption Details for the Auth0 SendGrid Email Provider
Last Updated:
Overview
The SendGrid email provider integration in Auth0 connects to SendGrid services using Simple Mail Transfer Protocol (SMTP) rather than the SendGrid Representational State Transfer (REST) Application Programming Interface (API). Auth0 encrypts this SMTP communication using the Transport Layer Security/Secure Sockets Layer (TLS/SSL) protocol via STARTTLS to prevent plaintext transmission.
