Cock.li vs Secria Mail

Cock.li is a public email host from Cock.li, founded in 2013, offering email accounts and webmail through the web, Android, and iOS. Its services are free, with the Free plan listed at free. Mail access includes IMAP and POP at mail.cock.li, while XMPP is listed at xmpp.cock.li. Registration does not require personally identifiable information. New accounts cannot send mail until the user completes a browser proof-of-work challenge that uses a few minutes of CPU time. Cock-mail is described as an open-source, client-side webmail client connecting directly to the IMAP server over websockets, but its 0.0.1 alpha release lacks major features including SMTP. The privacy policy says registration details, stored mail, XMPP data, and 48–72 hours of IMAP and SMTP logs may be retained. Email is automatically scanned for spam. Account information is encrypted server-side, but mail may travel without encryption when TLS is unavailable or not attempted.

Secria Mail is an email service that encrypts messages on the user’s device before they leave, with decryption intended for the recipient. It also describes zero-access encryption for stored mail. Its listed exchange methods combine ML-KEM-1024 and X25519; other specified protections include TLS 1.2+, DKIM, Argon2id password hashing, and per-email ephemeral keys. Tracking pixels are removed automatically, and senders do not see the user’s IP address or location. Email tools include aliases, attachments, rich text, folders, search, and mail import; the FAQ also describes PST import and export. Custom domains and Secria Sentinel breach alerts are available on paid tiers. Secria Mail runs on web, iOS, and Android. The Free plan costs nothing and lists 1 GB storage, two aliases, three folders, and mail import. Mail Plus is listed at $2.49 a year, billed $59.76 for two years and renewing yearly at $39 after that period. Secria says it does not use message content for advertising or sell personal information.
