Neir vs Private.Ki Mail

Neir is an email service with webmail, a desktop app, support for standard mail clients, Tor access, and a no-JavaScript webmail option. It supports IMAP, POP3, and SMTP clients including Thunderbird, Apple Mail, and Outlook, and is available on Android, iOS, Linux, macOS, Windows, and the web. Webmail message-body copies and attachments are encrypted to the account’s OpenPGP key, but ordinary email is not end-to-end encrypted by Neir: incoming mail arrives over SMTP in the open, and the mail system processes plaintext and retains protocol-compatible mailbox copies. The open-source desktop app, licensed under AGPL-3.0, includes native notifications, automatic locking, and a local cache sealed with a key from the system vault. The Free plan costs nothing and includes a 10 MB mailbox and 10 random aliases; sending to addresses outside Neir requires Pro. Pro costs $4.99 a month and includes a 5 GB mailbox, unlimited aliases, and external sending. Signup does not require a legal name, phone number, recovery email, birth date, or ID. Neir is based in Sweden.

Private.Ki Mail is an email service that encrypts messages between Private.Ki users. Message bodies, subjects, and attachments are encrypted on the sender’s device and decrypted on the recipient’s device, with encryption and signature checks shown for each message. Mail to outside providers uses end-to-end encryption when the recipient has a PGP key; otherwise it is delivered normally and marked accordingly. The Free plan costs nothing and includes one @private.ki address, encrypted email and messenger, signatures, recipient autocomplete, search, and attachments up to 25 MB per file. Undo send supports 5, 10, 20, or 30 seconds, and standard mailbox folders are included. Web, iOS, and Android access are listed. Security features include TOTP two-factor authentication, QR pairing, and device-bound sessions. The maker says it cannot recover a lost passphrase or protected key and has no independent audit yet.
