50 Reasons to Switch to Proton Mail

Fifty reasons to switch to Proton Mail, each linked to an email privacy guide.

Switch to Linux Reason #73: Choose an email client that does not feed an ad ecosystem

Email contains receipts, account resets, and intimate correspondence.

Switch to Protonmail Reason #18: Give political or advocacy groups an address separate from your daily identity

Association with a cause should not automatically expose the address used for banking or family mail.

Switch to Protonmail Reason #19: Separate job applications from accounts tied to your employer

Career moves can be sensitive.

Switch to Protonmail Reason #20: Limit the damage when a newsletter sells or shares your address

A newsletter signup can spread beyond the publisher through partners, brokers, or a breach.

Switch to Protonmail Reason #21: Send password-protected encrypted mail to someone outside Proton

Ordinary email to another provider may be readable by that provider.

Switch to Protonmail Reason #22: Set an expiration date on a password-protected external message

A sensitive link should not stay available indefinitely after its purpose ends.

Switch to Protonmail Reason #23: Use PGP with outside contacts who have configured it

A contact's unwillingness to change providers does not have to force plaintext email.

Switch to Protonmail Reason #24: Verify a trusted correspondent's PGP key before sharing sensitive information

Encryption to the wrong key can defeat the point of a protected message.

Switch to Protonmail Reason #25: Get a warning when a trusted contact's encryption key changes unexpectedly

A changed key can be legitimate, but it deserves attention before confidential mail goes out.

Switch to Protonmail Reason #26: Check a message's lock icon before assuming it was encrypted end to end

A secure-looking inbox does not mean every route to an outside recipient had end-to-end protection.

Switch to Protonmail Reason #27: Protect your mailbox with a security key or authenticator-based two-factor login

A stolen password can give an intruder access to your inbox and the reset links for many other accounts.

Switch to Protonmail Reason #28: Review authentication logs for suspicious account access

A quiet account takeover can continue while you assume your mailbox is safe.

Switch to Protonmail Reason #29: Get phishing warnings before trusting an impersonated sender

A fake invoice or reset notice can take credentials in minutes.

Switch to Protonmail Reason #30: Confirm a destination before opening a suspicious email link

A link can display one name while sending you to a lookalike login page.

Switch to Protonmail Reason #31: Filter known spam and malware before it lands in your inbox

Malicious attachments and scam campaigns often arrive as ordinary-looking mail.

Switch to Protonmail Reason #32: Use encrypted contacts for sensitive details such as phone numbers and addresses

A contact book can expose the identities and personal details of many people besides you.

Switch to Protonmail Reason #33: Detect tampering with supported signed contact information

Changing a stored contact detail could redirect a private message or call toward an attacker.

Switch to Protonmail Reason #34: Keep correspondence about health, finances, or legal matters encrypted in storage

Messages about a diagnosis, debt, or a dispute can remain in a mailbox for years.

Switch to Protonmail Reason #35: Reduce the value of a stolen copy of your provider's stored mailbox data

A mailbox breach can expose years of intimate content if the server stores it in readable form.
