Business Email That Isn't Google or Microsoft

For most small businesses I work with, business email comes down to two defaults: Google Workspace or Microsoft 365. Both are good products. Both are also American tech giants whose business model heavily involves data collection. If that bothers you — or if you handle genuinely sensitive client information — there's a third option worth knowing about: Proton.

What Proton actually is

Proton is a Swiss company that started with end-to-end encrypted email (ProtonMail) and has since expanded into a small suite of privacy-focused products: mail, calendar, cloud storage and VPN. The pitch is consistent across all of them: your data is encrypted so that even Proton can't read it.

For a small business, the relevant pieces are:

• Proton Mail — Email at your own domain ([email protected]), with encryption that goes beyond what Gmail or Outlook offer
• Proton Drive — Cloud storage equivalent to Google Drive or OneDrive
• Proton Calendar — Encrypted calendar that syncs across devices
• Proton VPN — A respected VPN, useful for testing how your website appears in different countries

The whole bundle is offered as a single business plan, similar in price to Google Workspace.

When Proton actually makes sense

It's not the right answer for everyone. The clearest cases where Proton wins:

• You handle sensitive client data. Lawyers, accountants, healthcare professionals, anyone bound by professional confidentiality requirements. End-to-end encryption isn't just nice-to-have — it's a compliance argument.
• Privacy is part of your brand. If you sell to customers who care about how their data is handled, using Google to send your customer emails is a quiet inconsistency.
• You want out of the Google/Microsoft ecosystem. Some small business owners are quietly tired of having every part of their business tied to two American advertising companies.
• You're starting fresh. It's much easier to begin a new business on Proton than to migrate an existing 50,000-email Google Workspace account.

Where it falls short

Honest comparison:

• No office apps. If your team lives in Word and Excel, you'll still need Microsoft 365. You can run it alongside Proton; they're not mutually exclusive.
• Calendar and contacts integration is fiddlier. Especially if you're booking meetings with people on Outlook or Google. Things mostly work, with rougher edges than the dominant platforms.
• Migration from Google or Microsoft is real work. Years of email, contacts, files, and calendars don't move themselves.
• It's not free. The free tier is limited — for business use you're paying.

Where it fits in your hosting setup

Email hosting is separate from website hosting, even though they share the domain. Your domain might be registered with one company, your website hosted with another, and your email handled by a third: Google Workspace, Microsoft 365, Proton, Fastmail, or someone else. I help clients pick whichever fits, then set up the DNS records that tie it all together.
