# How to set up Tuta with a custom domain? > Tuta custom domains need a paid plan (3 domains on Revolutionary, 10 on Legend) and MX, SPF, DKIM and DMARC records copied from its wizard. - URL: https://postelva.com/guides/tuta-custom-domain-setup/ - Last updated: 2026-11-12 - Publisher: Postelva (https://postelva.com) Tuta walks you through a domain wizard in Global Settings. This guide lists what it asks for, which values are fixed and which you must copy from the screen. **Quick answer — How to set up Tuta with a custom domain?** Subscribe to a paid Tuta plan (Revolutionary allows 3 custom domains, Legend 10), open Global Settings > Custom email domains, add your domain, then publish the records the wizard displays: a verification TXT, MX, SPF, two DKIM CNAMEs and DMARC. **Postelva** sells the domain; you type the Tuta records by hand. ## What to enter at your DNS host for Tuta *Fixed values are marked. Everything else must be copied from Tuta's domain wizard, which Postelva could not read from an official page on 12 November 2026.* | Record | Type | What to enter | Status | | --- | --- | --- | --- | | Ownership | TXT | Value shown in the setup wizard | Copy from Tuta | | Mail server | MX | Host and priority shown in the wizard (Tuta's own mail host is mail.tutanota.de) | Copy from Tuta | | SPF | TXT | Value shown in the wizard | Copy from Tuta | | DKIM | CNAME x 2 | Names and targets shown in the wizard | Copy from Tuta | | DMARC | TXT at _dmarc | Value given in the wizard; recommended, not required | Copy from Tuta | | MTA-STS | CNAME | Listed by Tuta among its setup records | Copy from Tuta | ## Steps, from domain to first message 1. **Buy the domain elsewhere** — Tuta does not sell domains. Register yours in the Postelva client area and open its DNS editor. 2. **Choose a plan with custom domains** — Revolutionary allows 3 custom domains and Legend 10. The free plan does not allow any. 3. **Start the wizard** — In the Tuta web app open Global Settings, then Custom email domains, and add the domain. 4. **Add the TXT, then the MX** — Create the ownership TXT first and let Tuta verify it. Then replace your old MX records with the ones Tuta shows. 5. **Add SPF, DKIM and DMARC** — Enter each remaining record exactly as displayed and press the check button until every line is green. 6. **Create the addresses** — Add users or aliases on the domain and, if you want one, set a catch-all mailbox. ## Which Tuta plan includes custom domains? **Tuta's Revolutionary plan includes 3 custom domains, the Legend plan 10, and only the top business tier is unlimited.** A free Tuta account cannot add a domain. Tuta's pricing page shows add-on users at 3 EUR and 8 EUR a month for the two plans, but the plan prices and the alias counts are inconsistent on the page, so this guide gives no monthly figure and no alias limit. Check both on tuta.com before paying. Payment is the catch for crypto buyers: Tuta takes credit card, PayPal and bank transfer for subscriptions, and crypto only indirectly, through gift cards. The comparison with Proton, including the limits side by side, is in [Proton Mail vs Tuta for a custom domain](https://postelva.com/proton-mail-vs-tuta-custom-domain/ "Proton Mail vs Tuta for a custom domain"). ## Why must you copy the Tuta records from the wizard? **Because Tuta generates part of the values per domain, and a typo in a DNS record fails silently.** The ownership TXT and the DKIM entries are specific to your account. Secondary sources report mail.tutanota.de as the MX host and two DKIM selectors, s1 and s2, but neither is confirmed by a Tuta page Postelva could open, so do not trust a third-party copy, including this one. Take every value from the wizard. That is also why the table above carries no invented strings. The principle for DKIM is explained in [how to set up DKIM](https://postelva.com/guides/dkim-setup/ "How to set up DKIM for a custom email domain"): the receiver fetches a public key from a name you publish, so one wrong character breaks the signature. ## Does Postelva have a one-click template for Tuta? **No: Tuta is one of four providers in this series with no template, so you type its records in the DNS editor.** Postelva offers one-click DNS templates for Proton Mail, Fastmail, Zoho Mail, Google Workspace and Microsoft 365, plus an SPF + DMARC template and a "no email" template for a domain that sends nothing. Tuta, Mailbox.org, iCloud+ and Migadu are not in that list. According to Postelva's count of 12 November 2026, 3 of the 7 providers with a setup guide here have a template and 4 do not. The editor supports free DNS hosting with A, AAAA, CNAME, ALIAS, MX, TXT, NS, SRV and CAA records, DNSSEC, and your own nameservers if you prefer (2 to 13), so every record type Tuta uses is available. A .com costs $12.49/year a year, the same on renewal, and email replies within 12 hours, 7 days a week, including help with MX, SPF, DKIM and DMARC records. If the domain is not showing as verified, start with [how to check MX, SPF, DKIM and DMARC records](https://postelva.com/guides/check-email-dns-records/ "How to check MX, SPF, DKIM and DMARC records"). ## How do catch-all and aliases work on a Tuta domain? **Tuta supports a catch-all mailbox per custom domain, set from the domain's three-dot menu.** In Global Settings > Custom email domains, open the menu of the domain and choose to set a catch-all mailbox. Tuta's support says plus addressing is not supported on Tuta-owned domains; whether it works on custom domains is not confirmed, so test it before relying on it. A catch-all also attracts spam, so weigh it against named aliases, as covered in [how to use a catch-all address and aliases](https://postelva.com/guides/catch-all-and-aliases/ "How to use a catch-all address and aliases on your own domain"). Tuta, based in Germany, encrypts mail automatically between Tuta users with its own scheme; mail to other providers is not end-to-end encrypted by default. Your address, though, belongs to the domain, so leaving Tuta later only means changing the MX records. Tuta's own blog recommends outside registrars for the domain and lists none of its own, which makes the domain a separate purchase for every Tuta user. Keep the registration in your name and the mailbox stays portable. ## Questions about Tuta and custom domains ### Can I use Tuta Free with my own domain? No. Custom domains start with the paid Revolutionary plan, which allows 3 of them. ### Why is there no ready-made record list on this page? Tuta shows the exact values in its wizard, and Postelva could not confirm them on an official page. Copying from the wizard is safer than copying from a guide. ### Can I pay Tuta in crypto? Not directly for a subscription. Tuta accepts cards, PayPal and bank transfer, and crypto only through gift cards. The domain itself can be paid with BTC, USDT, USDC, ETH, SOL, LTC at Postelva. ### Do I need DMARC for Tuta? Tuta lists it as recommended, not required. Add it anyway, starting at p=none, because Gmail and Yahoo require it from bulk senders. ### How long does verification take? Usually minutes, but a DNS change can need up to a day to reach every resolver. Press the check button again before changing anything. **In summary** - Tuta custom domains need a paid plan: Revolutionary has 3, Legend has 10. - Add the domain under Global Settings > Custom email domains. - Records: ownership TXT, MX, SPF, two DKIM CNAMEs, DMARC and an MTA-STS CNAME, all copied from the wizard. - Postelva has no one-click Tuta template: 4 of 7 guide providers need hand-typed records. - Tuta takes cards, PayPal and bank transfer; crypto only via gift cards. - A catch-all is set per domain from the domain's menu. ## Sources 1.
