What is a private alternative to Google Workspace for a custom domain email?

Why do people look for a Google Workspace alternative?

People leave Google Workspace for three reasons: price per user, the wish for end-to-end encryption, and the wish to move the address to another company's servers. The first is visible on the pricing page. Workspace bills per user, and its Starter plan was listed at EUR 6.80 a month per user, with Standard at EUR 13.60 and Plus at EUR 21.10, on an annual commitment billed monthly. One person with one address pays the same unit price as a team of ten.

The second reason is encryption. Proton Mail encrypts mail between Proton users with OpenPGP, and Tuta encrypts automatically between its own users with its own scheme. The third is portability, which depends on owning the domain and not on the provider.

Workspace also demands a domain: you bring one you own, or buy one. That is the opening for a separate registrar. The domain you register at Postelva works with Workspace, with Proton Mail, with Tuta and with any other provider, and a change of provider only touches DNS records.

Which alternative costs the least with a custom domain?

Zoho Mail Free costs $0 for 1 domain, Purelymail $10 a year, Migadu $19 a year and Proton Mail Plus $2.49 a month on a 12-month term. According to Postelva's index of 12 November 2026, six of the 14 providers checked have a plan with a custom domain under $5 a month, counting euro prices at face value. Google Workspace Starter, at EUR 6.80 per user, is above that line.

The cheaper plans differ in kind. Zoho Mail Free allows up to 5 users with 5 GB each, without IMAP, POP or Exchange ActiveSync. Migadu Micro allows unlimited mailboxes and aliases, capped at 200 messages in and 20 out a day. Purelymail's flat plan has no hard cap on domains or users. Proton Mail Plus allows 1 custom domain and 10 addresses, and its second year costs $47.88.

A yearly price comparison is only half the answer: the domain adds a fee. A .com at Postelva is $12.49/year and does not change on renewal. The page on how much a custom email domain costs adds both parts together.

Which alternative is the most private?

Proton Mail and Tuta are the two end-to-end encrypted options with a custom domain, and both are paid plans. Proton is based in Switzerland and Tuta in Germany. Mailbox.org, also German, offers optional PGP, which is not end-to-end by default. Fastmail and Migadu apply TLS in transit and no end-to-end encryption by default.

Encryption only covers messages between users of the same service, or messages you encrypt yourself with PGP or a password. For Proton, mail to outside addresses is not end-to-end encrypted unless you use PGP or password-protected mode, a point not re-verified on an official page on 12 November 2026. Fastmail and Migadu offer no end-to-end encryption by default at all.

For a detailed ranking by criteria, see the page on the best private email provider with a custom domain. For payment, Proton accepts Bitcoin as account credit with no autopay, while Tuta takes crypto only through gift cards.

How do I move from Google Workspace without losing mail?

Import the old mailbox first, change the MX records last, and keep the Workspace account until new mail has arrived. Forwarding alone moves only new mail, so the archive has to be copied over IMAP before the cutover.

The sequence has five steps:

1. Lower the TTL of your MX records to 300 to 600 seconds at least 24 to 48 hours before the move, because a DNS change spreads in about the time of the old TTL.
2. Add the new provider's domain and verify it.
3. Copy the archive with the provider's import tool.
4. Replace the Google MX records with the new provider's, and merge the SPF include into the single existing SPF record, since only one SPF record per domain is valid.
5. Raise the TTL again once mail arrives at the new provider.

Leaving the old MX records in place makes delivery unpredictable. The full procedure is in the guide on moving email to a new provider without losing mail, and the page on how to keep your email address when changing provider explains why the address survives.

What does Postelva add to a Workspace alternative?

Postelva adds the domain, and only the domain: it does not host mail, so it is not a Workspace replacement on its own. The mailbox comes from the provider you choose. Postelva registers the domain in your name through its ICANN-accredited registrar partner, 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.

It 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, free DNS hosting, and one price every year. We do not claim to be the cheapest. On the survey of 12 November 2026, a .com is $12.49/year against Namecheap's regular renewal of $19.98, which is 37% under it.

Postelva is a registrar for private email domains. It lets a person own the part of an address that no mail provider can take back.
