Proton Mail vs Secria Mail

Proton Mail is an encrypted email service available on the web, Windows, macOS, Linux, iOS, and Android. Its free plan lists 1 GB of storage and one email address, although its FAQ says storage starts at 500 MB; the free tier is described as having the same security level as paid plans. The service uses end-to-end and zero-access encryption, with open-source apps and independent audits. It blocks email trackers and includes phishing and spam protection, password-protected messages, and link confirmation. Users can schedule, undo, or snooze emails and organize messages with folders, labels, and categories. Easy Switch imports email, calendars, and contacts from other providers. Paid plans support external email clients through IMAP and SMTP using Proton Mail Bridge. Mail Plus lists 15 GB of storage, 10 extra email addresses, and one custom domain. Paid subscriptions include a 30-day money-back guarantee, and the desktop app has a 14-day free trial. Paid plans display monthly billing; the listed starting price is 3.99 /user/mo.

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.
