Email is effectively a plaintext communication sent from email clients to receiving email servers or from one server to another. This design limitation leaves the content of a message in transit open for anyone to eavesdrop; from a wireless hotspot at the airport or coffee shop to your ISP and internet backbone providers that carry your messages throughout the world.
Transport Layer Security (TLS) helps solve this issue by offering encryption technology for your message while it is “in transit” from one secure email server to another. That is, TLS helps prevent eavesdropping on email as it is carried between email servers that have enabled TLS protections for email. Just as TLS can be used to secure web communications (HTTPS), it can secure email transport.
