Switching email providers can be troublesome, especially when you are moving from a secure service like ProtonMail to Fastmail. If you are ready to switch, don’t worry, because there is a solution for you. This guide will provide you with simple steps to migrate from ProtonMail to FastMail efficiently. Let’s start reading.
ProtonMail is a secure email service developed by scientists from CERN and MIT. It is known for its end-to-end encryption and strong privacy policies. ProtonMail ensures that user data is protected under strict Swiss privacy laws. It also offers features like self-destructing messages, zero-access encryption, and no IP logging.
For these reasons, this email platform is a great choice for users who prioritize privacy and security.
However, due to this custom encryption model, it does not natively support the standard IMAP/SMTP protocols. Therefore, integration into other apps or logins requires the ProtonMail Bridge (which is only available with a paid subscription).
