Email encryption

Email encryption is the process of using secure cryptographic protocols to ensure email messages are encrypted before, during, and after sending. It’s important for email security because it prevents hackers from employing man-in-the-middle attacks, which put sensitive personal details of both brands and customers at risk.

Standard forms of email encryption include Transport Layer Security (TSL), Secure Socket Layer (SSL), and end-to-end encryption. TSL encrypts emails between senders and receivers, but it doesn’t necessarily encrypt emails before and after sending. End-to-end encryption, on the other hand, encrypts emails before, during, and after sending. Check out how Mailgun encrypts emails to protect your personal information.
