What it does
CounterMail is an encrypted-email provider that documents OpenPGP, alias support, custom domains and IMAP access. The official site also publishes service update notices.
CounterMail offers a browser mailbox and an IMAP route, with dynamic aliases, custom-domain support and OpenPGP for protected correspondence. Its published update notices provide service information for existing account holders.
The official invitation guide says registration requires a code, normally from someone already using CounterMail. A code opens a trial account and does not purchase a Premium subscription. The guide warns that alternative invitation queues can take a long time.
