Ensure 'Send email over a secure TLS connection' Is Enabled

HighLevel 1Manual reviewgoogle-workspace

Description

The default is that Gmail always tries to send messages over a secure TLS connection. If the receiving server doesn't use TLS, Gmail still sends messages with TLS but the connection isn't secure. This setting allows the option to require a CA-signed certificate, verify the hostname associated with the certificate, and test the TLS connection. A padlock image will appear next to the recipient address if the message will be sent with TLS. The padlock shows only for accounts with a Google Workspace subscription that supports S/MIME encryption. Google Workspace supports TLS versions 1.0, 1.1, 1.2, and 1.3. Transport Layer Security (TLS) encrypts email messages for security and privacy and prevents unauthorized access of messages when they're sent over internet connections.
