50 Reasons to Switch to Proton Mail

An inbox holds years of receipts, account access, relationships, and private conversations. These 50 reasons explain ways to reduce provider access, email tracking, address reuse, and account exposure. Each reason links to a guide with the relevant feature and its limits.

32. Use encrypted contacts for sensitive details such as phone numbers and addresses
33. Detect tampering with supported signed contact information

38. Give non-Proton contacts a secure way to reply to a password-protected message
39. Move a custom-domain address without giving every contact a new identity
40. Separate personal, public, and business mail with distinct addresses
41. Retire an exposed address while keeping your main mailbox
42. Monitor eligible addresses for discovered breach data with Dark Web Monitoring
43. Act sooner when an alias appears in a reported data leak

50. Start protecting future correspondence before another account or mailing list is breached

Begin with the conversations and signups that matter most. Ordinary email to an outside provider is not automatically end-to-end encrypted; choose password protection or PGP when that level of protection is required.
