Tuta is the lower-cost route to fully encrypted email. Its mailbox and contacts are end-to-end encrypted with what Tuta calls quantum-safe encryption, the apps are open source, and you can register without a phone number. The free plan gives a @tutamail.com or similar address with 1 GB, one calendar and three labels. Revolutionary costs $3.99 a month or $39.99 a year through the US App Store and adds 20 GB, unlimited labels and calendars, 15 extra addresses and 3 custom domains, while Legend raises storage to 500 GB with 10 domains for $9.99 a month. Encrypted full-text search, offline access and an encrypted calendar are included. The limits are real: there is no IMAP access for desktop clients, importing old mail requires Legend, and the free tier's 1 GB fills quickly for anyone moving years of messages.
