Reeva vs Tuta
Tuta (formerly Tutanota) is a Germany-based encrypted mail provider built around end-to-end encrypted messages between Tuta users. Reeva takes a different bet: privacy on top of open standards — JMAP, IMAP, SMTP, CalDAV — so every client just works. Here is how they compare.

- You prefer using existing clients over a single proprietary app.
When Tuta is the better fit
- End-to-end encryption between platform accounts is your top priority.
- You're comfortable using only the Tuta client (no standard IMAP / SMTP).

Tuta → Reeva: frequently asked questions
Why choose Reeva over Tuta?
Tuta encrypts everything end-to-end but uses a proprietary protocol, so it only works in Tuta's own apps — no IMAP, no Thunderbird, no Apple Mail. Reeva is built on open standards (JMAP / IMAP / SMTP, CalDAV / CardDAV), bundles a password vault and file cloud, and runs on the open-source Stalwart engine.
Can I migrate from Tuta to Reeva?
Tuta has no IMAP, so a direct server-to-server copy is not possible. Export your messages from the Tuta desktop app (.eml files), then import them into Reeva using a desktop client like Thunderbird. Calendars export as iCal and import via CalDAV.
Does Tuta work with standard mail clients?
No — Tuta only works in its own web, desktop and mobile apps. Reeva works with any standards-compliant client, including Thunderbird, Apple Mail, Outlook and K-9 Mail.
Is Reeva end-to-end encrypted like Tuta?
No. Tuta encrypts end-to-end between Tuta accounts at the cost of standard protocols. Reeva encrypts in transit (TLS) and at rest, and keeps JMAP / IMAP / SMTP compatibility. Pick by priority: strict E2EE between accounts → Tuta; open standards and client choice → Reeva.
