Proton Mail vs VibeMail

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.

VibeMail provides encrypted private email with multiple addresses, custom domains, and a transactional email API. It runs on Android, iOS, web, and through an API. Message bodies are encrypted at rest and in transit; the maker says it cannot read mail sealed with a password-derived key. Each alias has its own encryption identity. VibeMail says it shows no ads, does not profile users, and does not train models on customer mail. Incoming mail is scanned for spam and malware before encryption. The API supports templates, webhooks, delivery tracking, and suppression handling, with SDKs for TypeScript, Python, Go, and Rust, plus MCP and REST access. IMAPS, submission, and POP3S are supported, and the maker says Apple Mail, Gmail, and Outlook on mobile can connect through IMAP and SMTP. The free plan costs nothing forever with one encrypted address, 500 MB storage, and web access. Paid plans start at $2.99 a month; overage sends cost $0.60 per 1,000.
