Proton Mail Review: Encrypted, Ad-Free Email With a Free Plan
Proton Mail is an email service built around privacy. It doesn’t show ads, doesn’t scan your email to target ads, and encrypts your mailbox so that Proton itself can’t read the contents of your messages. It is run by Proton AG, a company based in Switzerland, which also makes a VPN, cloud storage, a calendar, and a password manager.

At a glance
- Best for: People who want an ad-free, private inbox, or a separate private address for health, legal, or financial matters.
- Price: Free plan with 1 GB of mail storage and one address. Mail Plus starts around $4 to $5 a month, depending on billing period. Family plans cover up to six people.
- Works on: Web, iPhone, Android, and desktop apps.
- Our verdict: Recommended for people who want private email. Not a must for everyone.
What Proton Mail does well
- Encrypted by design. Messages between Proton users are end-to-end encrypted automatically. Your stored mailbox is encrypted so Proton can’t read message contents.
- Private messages to anyone. You can send a password-protected email to someone who uses Gmail or Outlook. They open it in a browser with a password you share separately.
- No ads. Proton’s business is subscriptions, not advertising.
- Hide-my-email aliases. Even the free plan includes 10 aliases, separate forwarding addresses you can give to stores and newsletters. Paid bundles include unlimited aliases. See our email alias services review.
- Easy Switch. A built-in import tool can copy your email, contacts, and calendar from Gmail or Outlook.
- Clear family plans. Proton Family covers six people with 3 TB of shared storage.
Where it falls short
- The free plan is small. 1 GB of mail storage fills quickly if you get photos by email.
- Not everything is end-to-end encrypted. Subject lines and messages to non-Proton addresses (unless you set a password) travel like normal email. Proton is upfront about this.
- Searching message text takes a setting. Because Proton can’t read your mail, full-text search works on your device and may need to be turned on.
- Switching email is work. Every account that uses your old address needs updating. That is true of any new email service.
- Some features are paid. Using your own domain or connecting a desktop mail program through Proton Bridge requires a paid plan.
How to start with Proton Mail
- Create an account at proton.me or through the official app. Start with the free plan.
- Set up recovery right away. Add a recovery email or phone and save the recovery phrase Proton offers. Without recovery, a forgotten password can mean losing access to old messages.
- Turn on two-factor authentication in Settings, Account and password, using an authenticator app or security key. See our authenticator apps review.
- Use Easy Switch to import mail and set your old account to forward new mail to Proton.
- Move the important accounts first. Update the email on your bank, doctor’s portal, and government accounts. Leave newsletters on the old address.
- Keep the old account open for a year so you don’t miss password resets from forgotten accounts.
Tips for families and older adults
- A private address just for sensitive matters, like Medicare, bank alerts, and legal paperwork, is a reasonable middle step instead of moving everything.
- Encryption doesn’t stop phishing. A fake “Proton” or bank email can still arrive. Check links before you click. See Phishing, Malware, and Ransomware.
- Write the recovery phrase on paper and keep it with your password manager’s emergency information.
Our recommendation
If you want email that isn’t funded by ads, try Proton Mail’s free plan as a second, private address first. Upgrade if you outgrow 1 GB or want unlimited aliases. Move your main accounts over gradually, starting with banking and health.
FAQ
Can people with Gmail still email me at Proton?
Yes. Proton Mail works with any email address. Messages between Proton users get extra encryption automatically.
Is Proton Mail completely anonymous?
No email is completely anonymous. Proton collects much less than ad-supported services, but it follows the law where it operates, and your payment and recovery details are connected to your account.
Do I need a paid plan?
Not to start. The free plan is enough to try it and to use as a private second address.
