The mail is only as secure as who you send it too. If you email a Yahoo or Gmail account the email may be secure on your proton server but open to the others. The thing about security is everyone else has to do it or it breaks down. Gmail and other free email providers make it so easy people don't want to change.

Protonmail does have the ability to send emails in a secure fashion regardless of the receiver’s provider via a link.

Obviously it’s inconvenient and I wouldn’t use it for the lion’s share of my emails, but if I were sending something like a password or a code I certainly would.

You could send a link to a secure pastebin instead of the actual message.
