Hushmail vs Tau Mail

Hushmail provides encrypted email, secure web forms, and electronic signatures for individuals and businesses. It runs on Android, iOS, macOS, Windows, and the web, supports custom domains, and works with IMAP and SMTP. Hushmail says it combines OpenPGP with SSL/TLS, with messages between Hushmail customers remaining OpenPGP-encrypted on its servers. Secure-message recipients use an inbox link and may sign in with Google, Outlook, or Apple. Healthcare forms support encrypted responses, signatures, and templates for intake, assessments, file transfer, and appointment requests. Every healthcare plan includes a signed Business Associate Agreement, and the company says its healthcare service supports HIPAA compliance. Personal Use starts with 15 GB and unlimited aliases but is not intended for healthcare professionals and lacks an archive, BAA, and IMA. Personal Basic costs $59.99 a year; healthcare plans start at $14.99 a month.

Tau Mail is an email service with webmail and native Android and iOS apps. It says messages are encrypted on the device before leaving, with only the sender and recipient holding keys, and advertises zero tracking rather than inbox scanning for advertising profiles. On-device spam detection and priority sorting are described as working without uploading message content. Users can bring their own domain with full DNS control. Webmail uses the same login as the mobile apps and needs no installation. Mobile apps include inbox synchronization, calendar, and contacts. The service offers a free plan with 1 GB encrypted storage and one custom alias. Pro costs $8 a month and includes 50 GB encrypted storage, five custom domains, priority routing, and advanced filters. Business costs $16 a month with unlimited storage, a team admin console, audit trail exports, and dedicated support. Tau Mail is identified as a Tau Technology Group service.
