description CounterMail Overview

CounterMail is a privacy-focused email service that provides end-to-end encrypted communication for users seeking strong data protection. The service employs a zero-knowledge architecture, meaning user content is encrypted client-side and the provider cannot access message contents. CounterMail operates servers in Sweden, placing its operations under Swedish legal jurisdiction and data protection regulations. The service is designed for users who require robust encryption for their email communications.

help CounterMail FAQ

Can new users currently register for CounterMail?

CounterMail's live services page currently states that the service is closed for new registrations. The same page describes a 10-day trial only for people who receive an invitation from an existing CounterMail user. [CounterMail services](https://countermail.com/?p=services)

What does CounterMail's OpenPGP and diskless-server design mean?

CounterMail says it uses 4096-bit OpenPGP encryption and performs encryption operations on the user's side before messages leave the computer. It also describes diskless web servers, anonymous email headers, and an additional layer intended to protect against man-in-the-middle attacks.

Can CounterMail work with Thunderbird or a custom domain?

Premium users can use IMAP and SMTP with clients such as Thunderbird, and a custom domain option costs a $15 one-time setup fee. CounterMail also offers a USB-key login for webmail, but its support page recommends keeping at least two activated USB keys because losing both can mean losing account access.
