Proton

One of the most recommended private email providers, ProtonMail allows you to send and receive encrypted emails for free. It’s one of the most popular email services available on the Dark Web and even has a surface web version if you prefer. It uses end-to-end encryption to help keep users anonymous while giving them access to quality email. Unlike other services, it even includes an automated login recovery system if you lose your credentials. It’s also much more secure than popular platforms.
