Tuta Mail (rebranded from Tutanota in 2023) does not support standard IMAP, POP3, or SMTP protocols. This applies to every Tuta domain: @tuta.com, @tuta.io, @tutanota.com, @tutanota.de, @tutamail.com, @tutao.de, and @keemail.me. There is no bridge app, no paid tier that unlocks external clients, and no plan to add these protocols. The only supported access methods are the official Tuta apps (Windows, macOS, Linux, iOS, Android) and the webmail at app.tuta.com. This is a deliberate architectural choice tied to Tuta’s proprietary encryption model, and it is the single most important thing to understand before choosing Tuta as your primary provider.
Setup gotcha
No IMAP/SMTP/POP3Closed protocol
Tuta uses a proprietary end-to-end encryption protocol that is not compatible with standard IMAP, POP3, or SMTP. Unlike Proton Mail which provides a Bridge app on paid plans, Tuta has no equivalent workaround. Outlook, Thunderbird, Apple Mail, K-9 Mail, FairEmail, and every other third-party mail client cannot connect to a Tuta mailbox. This is not a bug or a plan tier limitation: it is the architecture. If your workflow requires a standard mail client, Tuta is not the right choice regardless of plan.
How Tuta Mail is accessed
Tuta provides four supported entry points to a mailbox. All of them use Tuta’s encrypted protocol over HTTPS to talk to Tuta’s servers, and all of them handle decryption client-side. No standard mail-protocol port (25, 110, 143, 465, 587, 993, 995) is open.
| Access method | Availability | Notes |
|---|---|---|
Webmail at app.tuta.com | All plans (Free included) | Primary access. Works in any modern browser. |
| Tuta desktop app (Windows, macOS, Linux) | All plans | Native app wrapping the same interface as webmail. Offline access. |
| Tuta iOS app | All plans | Native iOS mail app. Not compatible with Apple Mail. |
| Tuta Android app | All plans | Native Android app. Available on Google Play and F-Droid. |
| IMAP, POP3, SMTP | Not supported on any plan | No third-party client can connect. |
Why Tuta does not offer IMAP or SMTP
Tuta encrypts more than message bodies. Subject lines, attachments, address book contacts, and calendar entries are all encrypted end-to-end using the account’s private key, which never leaves the client. Standard IMAP transmits subject lines and message metadata in plaintext, which would leak precisely the information Tuta encrypts. SMTP similarly assumes plaintext handoff between servers, which conflicts with Tuta’s insistence that ciphertext never leaves the client unencrypted.
Tuta could theoretically ship a Bridge-style local proxy the way Proton does, but has publicly stated it will not: the proprietary protocol allows continuous evolution (post-quantum encryption is being rolled out, for example) that a fixed SMTP/IMAP bridge would slow down. The tradeoff Tuta chose is stronger encryption in exchange for narrower client options.
Tuta Mail plans and domains
| Plan | Price (approx) | Storage | Domain options |
|---|---|---|---|
| Free | 0 EUR | 1 GB | @tuta.com, @tuta.io only |
| Revolutionary | ~3 EUR/month annual | 20 GB | All Tuta domains + 1 custom domain |
| Legend | ~8 EUR/month annual | 500 GB | All Tuta domains + 3 custom domains + 30 aliases |
| Team / Business | Custom | Varies | Custom domain + team seats |
Alternatives if you need standard IMAP or SMTP
If Tuta’s closed protocol is a dealbreaker but you still want a privacy-focused mailbox, three alternatives work with any mail client out of the box: Mailbox.org (Germany, from 1 EUR/month, standard protocols with optional PGP), Posteo (Germany, 1 EUR/month flat, anonymous signup), and Runbox (Norway, low-cost tiers). If you can accept a bridge app on desktop, Proton Mail is the closest match to Tuta on default end-to-end encryption while still allowing external clients on paid plans via the Proton Mail Bridge desktop app.

Frequently asked questions
Can I configure Outlook or Thunderbird for a Tuta Mail account?
No. Tuta does not support IMAP or SMTP on any plan, and there is no bridge app equivalent to Proton Mail Bridge. Outlook, Thunderbird, Apple Mail, and every other third-party mail client cannot connect to a Tuta mailbox. The only supported clients are Tuta’s own official apps for desktop, iOS, and Android, plus webmail.
What happened to Tutanota? Is Tuta the same service?
Tuta is Tutanota. The company rebranded in 2023, shortening the name from Tutanota to Tuta. Existing @tutanota.com and @tutanota.de addresses continue to work, the account credentials did not change, and the underlying infrastructure is the same. The apps and the webmail URL moved to Tuta branding (app.tuta.com, formerly mail.tutanota.com).
How does Tuta compare to Proton Mail for third-party client access?
Proton Mail provides a desktop Bridge app on paid plans (Plus tier and above) that exposes local IMAP and SMTP endpoints so mail clients can connect. Tuta does not. If third-party client access matters and end-to-end encryption is also required, Proton Mail is the closer fit; if you are comfortable with Tuta’s app-only model, Tuta remains a strong privacy option.
Can I forward Tuta messages to another provider that has IMAP?
Tuta does not offer server-side automatic forwarding to non-Tuta addresses on Free or Revolutionary plans; Legend and business plans include forwarding. Even where forwarding is available, forwarded messages are decrypted before leaving Tuta’s infrastructure, which weakens the end-to-end encryption for those specific messages. Most users who need standard IMAP access are better off migrating to a different provider entirely.
Does the Free plan include third-party client access?
No, and neither do any paid plans. Tuta’s Free plan gives 1 GB storage, access to @tuta.com and @tuta.io addresses, and use of the official apps and webmail. Third-party mail clients are not supported on any tier because the protocol itself is not exposed, not because of a plan gate.
Can I use Tuta with mobile mail apps like K-9 or FairEmail?
No. K-9 Mail, FairEmail, Apple Mail on iPhone, the Gmail app, and every other mobile mail client require IMAP or Exchange, neither of which Tuta supports. Use the official Tuta app on iOS and Android.
Where is Tuta webmail located?
Webmail is at app.tuta.com. The old mail.tutanota.com URL redirects to it. Bookmark app.tuta.com to avoid phishing pages that impersonate the Tuta login.
About this guide
Tuta protocol limitations were verified against Tuta’s official documentation at tuta.com in July 2026. The absence of IMAP, POP3, and SMTP is a longstanding architectural decision that has been consistent through the Tutanota-to-Tuta rebrand and is unlikely to change. SMTPedia re-verifies each provider quarterly and after any announced infrastructure change.
