SSL Certificate

A Secure Sockets Layer (SSL) certificate is an encryption standard that ensures communication between two parties stays safe and secure. Websites secure with SSL certification contain an “s” after “HTTP,” like https://mailgun.com. Like web pages, brands can secure email communication through SSL certification or other encryption standards like Transport Layer Security (TLS) or end-to-end encryption.

SSL certification builds trust between a brand and its subscriber, enabling the subscriber to confidently share their personal information. Once the conversation is encrypted, it’ll never be available to the public, despite being on the internet.
