TLS Version 1.0 and 1.1 Deprecation
Since Mailgun’s early days, we’ve made a point to ensure that our senders could send their emails as securely as possible. When we announced TLS support in 2014, we did this with the customer in mind, and we continue to do so now as we move to deprecate TLS 1.0 and 1.1 in favor of the more secure TLS version 1.2.
