CounterMail vs EPRIVO

CounterMail is an email service that applies encryption automatically and says each message is encrypted before leaving the user's computer. It supports communication with OpenPGP-compatible email users and provides an IMAP server for third-party email clients. Premium subscriptions include 4 GB of encrypted storage per mailbox, with additional storage available for a one-time fee. Other listed tools include dynamic aliases, filters, notifications, an autoresponder, password manager, secure forms, and an XMPP chat server. CounterMail lists SSL-MITM protection, diskless web servers, SSL encryption and authentication, and anonymous email headers. Its privacy policy says it does not log IP addresses and keeps email bodies and attachments encrypted; its servers are in Sweden, as is the maker's headquarters. The service supports Android, Linux, macOS, web, and Windows. Pricing is listed from $3.29/user/mo, with a 10-day trial for people who already know a CounterMail user. New registrations are closed.

EPRIVO provides private email, collaboration, and online privacy products for consumers and organizations across Android, iOS, macOS, web, and Windows. Users can secure an existing email address or create an EPRIVO virtual address. Email controls include recall, viewing restrictions, expiration, and forwarding limits; past messages can be archived and encrypted. Private voice messages use the same controls as text messages and, according to EPRIVO, cannot be saved. Mobile apps can add end-to-end encryption and privacy controls to regular or group Telegram chats. Private Collaboration supports encrypted group activities, milestones, shared resources, and message controls. Private Identity Guard creates virtual registration addresses, forwards authenticated messages, and alerts on privacy leakage. EPRIVO describes zero-knowledge encryption with a device-generated key and physical separation algorithms. It states support for GLBA, SOX, HIPAA, FERPA, and GDPR. A 14-day trial is available, and plans include individual, family, celebrity, organization, and lifetime options.
