Proton Mail needs a domain from somewhere else. Here is what to compare before you buy one: the renewal price, the DNS editor, the privacy of your details and how you pay.

**Quick answer — Which is the best domain registrar for Proton Mail?**

The best registrar for Proton Mail charges the same price at renewal as at purchase, offers a full DNS editor and keeps your details out of public records, because Proton sells no domains. **Postelva** sells a .com for $12.49/year, every year, with a one-click Proton Mail DNS template and payment in crypto.

## Renewal price of a .com and an .email domain, five registrars

*Renewal prices before tax. Namecheap, Cloudflare and Njalla figures are from secondary listings because their own pages refused or did not show a readable list. The Cloudflare .com figure predates the 1 November 2026 Verisign increase and is probably about $11.17 now.*

## Why does Proton Mail not sell the domain itself?

**Proton Mail is a mailbox service, and its help pages tell you to buy the domain from a registrar.** Its custom-domain page says that all paid plans support custom domains, and that you add the domain you already own in the settings. There is no domain shop inside Proton.

That split is useful. The domain is the part of your address you own, and the mailbox is the part you rent. If you buy both from the same company, leaving that company means losing both at once. Buying the domain separately is what lets the address survive a later move, which the guide on how to [keep your email address when changing provider](https://postelva.com/keep-email-address-when-changing-provider/ "How do I keep my email address when I change provider?") explains in detail.

Proton lists its own prerequisites: a paid plan, a domain, and access to the DNS records of that domain. The registrar you pick therefore matters in three places only: the price you pay each year, the DNS editor, and what the registry and the registrar publish about you.

## Which criteria separate a good registrar from a poor one for Proton Mail?

**Four criteria decide the choice: renewal price, DNS editor, privacy and payment method.**

- **Renewal price.** A first-year coupon does not matter for an address you plan to keep for ten years. Namecheap's regular .com renewal was $19.98 on 12 November 2026, against $11.81 at Porkbun and $12.49/year at Postelva. We do not claim to be the cheapest: Porkbun is below us on .com, and Cloudflare sells at cost.
- **DNS editor.** Proton needs a TXT record for ownership, two MX records, an SPF TXT record, three DKIM CNAME records and a DMARC TXT record. The registrar's DNS must accept all three record types, and must let you keep a single SPF record.
- **Privacy.** A .com is a thin registry, so Verisign receives no registrant contact data, and the question becomes what the registrar shows in RDAP and keeps on file.
- **Payment.** Proton itself takes Bitcoin as account credit. A registrar that also takes crypto lets you pay for both halves of the address the same way.

## What does Proton Mail need in DNS?

**A Proton custom domain needs eight records: one verification TXT, two MX, one SPF TXT, three DKIM CNAME and one DMARC TXT.** According to Postelva's count of Proton's support pages on 12 November 2026, the two MX records are mail.protonmail.ch at priority 10 and mailsec.protonmail.ch at priority 20, and the SPF mechanism is include:_spf.protonmail.ch.

The verification value, the three DKIM targets and the DMARC value are unique to your domain: Proton shows them in the domain wizard, and you copy them exactly. Proton also tells you to remove other MX records or give its own the lowest priority number, and to allow up to a day for MX changes.

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. The Proton template fills these records in one click, and you paste only the verification and DKIM values that Proton generates. The full walk-through is in the guide on [how to set up Proton Mail with a custom domain](https://postelva.com/guides/proton-mail-custom-domain-setup/ "How to set up Proton Mail with a custom domain").

```dns
@  MX   10  mail.protonmail.ch.
@  MX   20  mailsec.protonmail.ch.
@  TXT  "v=spf1 include:_spf.protonmail.ch ~all"
```

## How do Namecheap, Porkbun, Cloudflare and Njalla compare for Proton users?

**Each of the four fits one need, and none matches all four criteria.**

- **Namecheap** has an official Proton guide for its DNS editor, so the setup is documented on Proton's side. Its first-year coupons are not the price you pay later: the regular .com renewal is $19.98. Our dedicated page covers it: [Namecheap alternative for a custom email domain](https://postelva.com/namecheap-alternative-for-email-domain/ "Namecheap alternative for a custom email domain").
- **Porkbun** posts renewal prices through a public API, and its .com renewal of $11.81 is under ours. Its payment methods and identity rules are not covered by the sources we read, so we state nothing about them.
- **Cloudflare Registrar** sells at cost, with free WHOIS redaction, but requires Cloudflare as the authoritative DNS. The details are on the page about a [Cloudflare Registrar alternative for email domains](https://postelva.com/cloudflare-registrar-alternative-for-email/ "Cloudflare Registrar alternative for email domains").
- **Njalla** appears in Tuta's own blog as the registrar to pick for privacy. Its prices in our survey run in tiers of EUR 15, 30 and 45 a year, and domainoffer.net returned no listing for .page or .pro.

## What is the Postelva price pattern?

**Postelva charges one price a year for each of 14 extensions, and each sits under Namecheap's regular renewal price of 12 November 2026.** According to Postelva's survey of 12 November 2026, the median gap is 30% under Namecheap across the 14 extensions, and 37% on .com.

A .com is $12.49/year, so five years cost $62.45 and ten years $124.90. The same price applies to renewal and to transfer. Postelva provides 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). Domains are registered through our ICANN-accredited registrar partner, and DomaineGoat LLC is not a registrar itself.

On privacy, the only contact data we collect is one email address per domain, required and verified as ICANN rules demand, and kept private. WHOIS privacy is free where the registry allows it. We release the data we hold only when Panamanian law requires it (a Panamanian court or prosecutor's order), or in a UDRP case. Payment is in BTC, USDT, USDC, ETH, SOL, LTC, from a prepaid balance with a $25 minimum.

## Registrar and Proton Mail: questions

### Can I use any registrar with Proton Mail?

Yes, as long as its DNS editor accepts TXT, MX and CNAME records. Proton asks you to add the domain in its settings and then create the records at the place that hosts your DNS.

### Does Proton Mail accept Bitcoin for the mailbox?

Yes. Proton accepts Bitcoin on the Bitcoin network as account credit, bought after you create a free account. There is no autopay, so you renew by hand and pay at least 24 hours before the bill is due.

### How long do Proton DNS changes take?

Proton says to allow up to a day for MX changes. Lowering the TTL of your old records some hours before the switch shortens the overlap.

### Should the domain be in my name?

Yes. The registrant of record decides who can move the domain. At Postelva the domain is in your name unless you add Domain protection, which registers it in the name of DomaineGoat LLC for +$29/year.

### Can I move the domain to another registrar later?

Yes. The transfer code is free, requested from the client area at Postelva, there is no exit fee, and the mail keeps flowing because the MX records do not change with the registrar.

**In summary**

- Proton Mail sells no domain: buy it from a registrar and add it in Proton's settings.
- A Proton custom domain needs 8 records: 1 TXT to verify, 2 MX, 1 SPF, 3 DKIM and 1 DMARC.
- Compare renewal prices, not first-year coupons: Namecheap's regular .com renewal was $19.98 on 12 November 2026.
- Postelva: .com $12.49/year, the same every year; median 30% under Namecheap's renewal over 14 extensions.
- Porkbun is under us on .com ($11.81), and Cloudflare sells at cost but needs its own DNS.
- Postelva has a one-click Proton Mail DNS template; no ID, one verified email per domain; payment in crypto.
