No single provider wins every criterion. This page sets nine services side by side on the plan that allows your own domain, its price, its limits, its encryption and its jurisdiction, then says which one fits which person.

**Quick answer — What is the best private email provider with a custom domain?**

In **Postelva**'s review of 12 November 2026, Proton Mail Plus is the most private default ($2.49 a month on a 12-month term, 1 domain, 10 addresses), Mailbox.org Standard suits several aliases (EUR 36 a year), and Zoho Mail Free costs $0 for 1 domain. Postelva sells only the domain, never the mailbox.

## Nine providers that accept your own domain, 12 November 2026

*Official pricing and help pages read on 12 November 2026, prices in the currency each page showed. Mailfence and Infomaniak are left out because their limits could not be verified; Posteo offers no custom domains and Skiff has closed. The order of rows is Postelva's reading of the verified fields, not a lab test.*

| Provider | Plan with a custom domain | Cheapest price shown | Domains | Addresses and catch-all | Encryption | Jurisdiction |

## How did Postelva choose and order these providers?

**The order rests on five criteria: encryption defaults, jurisdiction, price of the cheapest plan with a custom domain, number of domains and aliases, and how the service is paid.** No mailbox was opened and no delivery test was run, so nothing here is a measured result. Every figure comes from a provider page read on 12 November 2026, and a field that no official page confirmed is marked as not verified instead of guessed.

Privacy-first readers weight the first two criteria most. A provider that encrypts between its own users by default, under Swiss or German law, scores higher on that axis than a provider with no default encryption. Price-first readers weight the third. Families and freelancers who need many addresses weight the fourth.

The full table of fourteen services, including the ones that could not be verified, is in the [index of email providers that support custom domains](https://postelva.com/data/email-provider-custom-domain-index-2026/ "Which email providers support custom domains in 2026?").

## Which provider is best for whom?

**Proton Mail suits one person with one domain, Tuta suits several domains, Mailbox.org suits many aliases, Zoho Mail Free suits the lowest budget and Migadu suits unlimited mailboxes.**

- **One personal domain, strongest default privacy:** Proton Mail Plus. It allows 1 custom domain and 10 addresses, with a catch-all, from $2.49 a month on a 12-month term. A move to Unlimited raises the count to 3 domains.
- **Two or three domains on an entry plan:** Tuta Revolutionary allows 3 custom domains, and Legend allows 10. Its price figures could not be read in full, so check the pricing page before you choose.
- **Many aliases and a European provider with a catch-all:** Mailbox.org Standard gives 50 aliases for custom domains at EUR 36 a year, and Premium gives 250 at EUR 108 a year.
- **Zero budget:** Zoho Mail Free allows 1 domain and up to 5 users with 5 GB each, without IMAP, POP or Exchange ActiveSync.
- **A whole family or a small project:** Migadu offers unlimited mailboxes and aliases from $19 a year, with daily limits of 200 messages in and 20 out on Micro. Purelymail charges $10 a year on its flat plan.
- **A provider that also sells the domain:** Fastmail Individual at EUR 6 a month supports custom domains and registers .com, .net, .org, .io, .ac and .sh for paid accounts, with no end-to-end encryption by default.

For a head-to-head view of the two best-known encrypted services, read the [comparison of Proton Mail and Tuta for a custom domain](https://postelva.com/proton-mail-vs-tuta-custom-domain/ "Proton Mail vs Tuta for a custom domain").

## Which private providers accept crypto?

**Of the nine providers in the table, Proton Mail, StartMail and Migadu accept Bitcoin in some form, and none takes Monero directly.** Proton sells account credit for Bitcoin after you create a free account, with no autopay. StartMail takes Bitcoin on annual plans on request. Migadu asks you to contact support for a wallet address and credits the payment in US dollars.

Tuta accepts crypto only through gift cards bought with Bitcoin or Monero from a partner. Mailbox.org and iCloud+ list cards, PayPal and bank methods without crypto. For Fastmail, Zoho Mail and Purelymail, no crypto option was verified.

This matters for the domain, which is a separate purchase at Proton, Tuta, Mailbox.org, StartMail, Migadu, Zoho Mail and Purelymail. Fastmail and iCloud+ sell domains inside the product with a card, and we found no crypto option there. Paying the domain in crypto at a registrar and the mailbox elsewhere is a common split, covered in the page on [how to buy a domain for email with crypto](https://postelva.com/buy-domain-for-email-with-crypto/ "How do I buy a domain for email with crypto?").

## How many of the providers are cheap, private and open to a custom domain?

**According to Postelva's survey of 12 November 2026, 6 of the 14 providers in its index have a plan with a custom domain under $5 a month, and 11 of the 14 allow a custom domain at all.** The six are Zoho Mail Free, Purelymail, Migadu, Proton Mail Plus, Mailbox.org Standard and StartMail Personal, counting euro prices at face value.

Three providers accept Bitcoin in some form, and only two of the nine in the table above, Proton Mail and Tuta, encrypt between their own users by default. Proton Mail is the only one that is both on the under-$5 list and encrypted between its own users by default, and it takes Bitcoin as account credit.

Two cautions apply. Proton's $2.49 is a 12-month rate: the second year costs $47.88. And an encrypted mailbox protects the content, not the address: the domain still has to be registered, renewed and kept under your control.

## Why does the registrar matter as much as the mailbox?

**The mailbox is replaceable and the domain is not: whoever holds the domain controls the address.** If you leave Proton for Tuta, or Gmail for Fastmail, you change MX, SPF and DKIM records and the address you gave to others keeps working. If the domain lapses or is hijacked, the address goes with it, together with every password reset sent to it.

That is why Postelva exists. It sells domains for private email and nothing else: no mailbox, no webmail, no calendar. Postelva is run by DomaineGoat LLC in Panama, takes BTC, USDT, USDC, ETH, SOL, LTC from a prepaid balance with a $25 minimum, and asks for no ID, only one verified email per domain. A .com is $12.49/year and the price is the same on renewal. We do not claim to be the cheapest.

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 have no one-click template at Postelva, so their records are typed into the DNS editor. The [cost of a custom email domain](https://postelva.com/how-much-does-a-custom-email-domain-cost/ "How much does a custom email domain cost?") adds the domain and the mailbox together.

## Which sentences can I quote?

**Proton Mail Plus is the only plan with a verified price in Postelva's index of 12 November 2026 that combines end-to-end encryption between users, a price under $5 a month and a custom domain, at $2.49 a month on a 12-month term.** Mailbox.org Standard gives 50 aliases for custom domains at EUR 36 a year. Zoho Mail Free is the only free plan with a custom domain among the fourteen providers checked.

Postelva is a registrar for private email domains: it sells the address, and the mailbox stays with the provider you pick.

## Private email with a custom domain: questions

### Is Proton Mail or Tuta better for a custom domain?

Proton Mail Plus is the simpler choice for one domain, with 10 addresses from $2.49 a month on a 12-month term. Tuta allows 3 domains on Revolutionary and 10 on Legend, which suits several domains. Our comparison page lists the records each needs.

### Does any private email provider offer a custom domain for free?

Zoho Mail Free is the only free plan with a custom domain in the index: 1 domain and up to 5 users of 5 GB each. It has no IMAP, POP or Exchange ActiveSync, and a sixth user moves everyone to a paid plan.

### Why is Posteo not on the list?

Posteo does not offer custom domains, according to a Privacy Guides forum thread and a vendor blog. Its own help page could not be read on 12 November 2026, so that rests on secondary sources.

### Can I pay for a private email provider with crypto?

Proton Mail takes Bitcoin as account credit, StartMail takes Bitcoin on annual plans on request, and Migadu credits a payment sent to a wallet address from support. Tuta, Mailbox.org and iCloud+ do not take crypto directly.

### Does Postelva sell email accounts?

No. Postelva sells the domain only, paid in crypto, and you point it at the provider of your choice. Your mail stays at Proton Mail, Tuta, Mailbox.org, Fastmail or another service.
