What Proton Mail's own pages show
Suits
- People who want an email provider that cannot read their messages
- Anyone moving off Gmail, Outlook or Yahoo who needs to import old mail
- Users who want email, VPN, passwords and storage from one vendor
Limits worth knowing
- The free plan is limited to 1 address, up to 1 GB of mail storage and 150 sent messages a day.
- Custom domains and IMAP/SMTP access through Bridge need a paid plan.
- The desktop apps need a paid plan; free accounts get a 14-day trial of them, and the Linux app is labeled beta.
- Buying in the iOS app costs more: the US App Store lists Mail Plus at $5.99 monthly, against $4.99 on Proton's site.
