Onion Mail is an anonymous email service for privacy-conscious individuals, journalists, activists, researchers, and others who want email access without providing personal information at registration. It combines webmail, native Tor .onion access, PGP encryption with user-provided public keys, email aliases, and IMAP/SMTP support for external email clients. The Free plan includes receiving email, 50 MB of storage, PGP encryption, and .onion access.

The paid structure adds outbound sending across the Basic, Medium, and Pro plans. These plans also include Tox account recovery, unlimited email aliases, PGP and post-quantum encryption, data breach monitoring, and image metadata removal. The displayed prices are monthly equivalents charged as a single annual installment. This makes the service suitable for users who need sending capabilities and additional privacy controls, while the Free plan fits primarily receive-only use.

Privacy features are the main reason to consider Onion Mail. Tor access and anonymous registration support a lower-information account setup, while PQC Server provides post-quantum encrypted messaging. However, its native interface is web-based, with IMAP/SMTP available for external email clients rather than a broader native platform offering. PGP zero-access protection also depends on configuring a personal PGP key; without one, infrastructure-held keys may theoretically be accessible to administrators. Choose Onion Mail for anonymous, Tor-accessible encrypted email; choose an alternative if broader platform coverage or simpler key management is more important.
