Proton Mail: Encrypted Email With Your Own Domain for Freelancers

Proton Mail is the encrypted email service from Swiss provider Proton — known as the counterpoint to Gmail and Outlook. For freelancers and the self-employed who want a professional address on their own domain, without a US tech giant reading their client mail, it's the obvious privacy-first alternative.

What is Proton Mail?

Proton Mail is an email service where your messages are stored with end-to-end and zero-access encryption — Proton itself can't access the contents of your emails, contacts or calendar. What matters most for freelancers is the combination of encryption and a custom domain: instead of @proton.me you communicate as you@yourname.com, which looks professional while your data sits under Swiss jurisdiction. There are native apps for iOS, Android, macOS and Windows, plus the web interface.

The key point: encryption and jurisdiction

The core argument is end-to-end encryption combined with location. Proton is a Swiss company headquartered in Geneva; its servers sit in Switzerland, Germany and Norway. Switzerland deliberately sits outside US jurisdiction and is considered one of the strictest privacy environments in the world. Proton is subject to Swiss data protection law and can be used in a GDPR-compliant way for clients who need it. Anyone working with legal, health or coaching records gets a far stricter framework than with a US provider — and no obligation to hand over data under US warrants.

Custom domain: the reason for Mail Plus

The free plan gives you an encrypted @proton.me address and 1 GB of storage — fine to try, but no custom domain. For credible freelance communication, the jump to Mail Plus (from $3.99/month) is the real step: your own domain, 10 addresses, 15 GB of storage, plus catch-all, filters, auto-replies and 10 hide-my-email aliases that mask your real address when signing up for newsletters or accounts. That lets you run separate addresses like hello@ and billing@ under your domain without paying for multiple mailboxes.

The plans

Three individual tiers, and the decision is storage and domains. Free gives you one address and 1 GB — the free-forever entry point. Mail Plus is the jump for anyone with a business address: a custom domain, ten addresses and 15 GB. Proton Unlimited raises storage to 500 GB with three domains and bundles the whole Proton ecosystem — VPN, the Pass password manager, Drive storage and the Scribe AI writing assistant — which is only worth it if you would pay for two of those anyway. What the cards cannot show: monthly billing costs about a quarter more than annual, Scribe is a 14-day trial on Unlimited and then a paid add-on, and teams needing central administration are on the separate Business plans, covered in the Proton for Business review.

Where Proton Mail hits its limits

The strengths have a flip side. Because everything is encrypted, server-side full-text search is limited — Proton offers a local search instead, but it's less convenient than Gmail's. There are no native integrations into third-party workflows: you work in Proton's own ecosystem, not Google Docs attachments; Outlook or Apple Mail need the Bridge app, which paid plans include. And switching means a one-time import of your old mail, for which Proton ships a migration tool. If you're deep in Google, weigh whether the privacy gain is worth the convenience you give up.

Who is Proton Mail worth it for?

Proton Mail suits privacy-conscious freelancers and solo businesses who want a professional address on their own domain and value Swiss jurisdiction — especially those handling sensitive client data (legal, health, coaching, journalism). It's less of a fit for anyone tied to Google's collaboration and search. If you just want free encrypted email, start on the Free plan; if you want to look professional, take Mail Plus.

Proton Black Friday 2026: what to expect

Proton is one of the few vendors where November genuinely brings a special price. Proton excludes its business plans from it, explicitly.

Proton's own Black Friday FAQ excludes the business plans in so many words, and the business page carried no occurrence of the term on either Black Friday itself. If you are licensing for a team, waiting through November gains you nothing.

Two things about how to read this. The specific percentages that can be evidenced on Proton's own pages concern the VPN plans; for the mail plans the campaign itself is documented, its depth is not. And Proton calculates the discount against the monthly list price, not against the regular annual price — which makes the saving look larger than it is next to an ordinary annual subscription.

The advertised monthly figure also assumes payment upfront for the full term.
