What Is TLS And How Does It Help Protect My Emails?

Transport Layer Security (TLS) is a protocol that secures your emails by encrypting the connection from the sender to the recipient (client to server). Encryption makes snooping of your emails much harder as they travel to their recipients.

Encryption in transit is extremely important to ensure that your emails are only being read by intended recipients and not by anyone else on the way.

When two servers connect to each other, they negotiate on an encryption method to secure the communication channel. In case, the negotiation fails or if it is not possible, then it is up to servers to decide to send the emails unencrypted. This means that emails are sent in clear text and anyone on the network can read them. Alternatively, if the negotiation either fails or is not possible, then, the sending server may decide to not send the email.
