Yes, absolutely. Our password protection feature allows you to email people who use other email hosting providers and for it still to be encrypted. Your recipient will receive an email with a link to the whole message, which will be hosted on our secure servers. The message will only be decrypted when the recipient enters the correct password. After reading, the recipient can reply back securely from the same page.
Using passwords like this means only the recipient (who knows the password you set) can read the email. It’s a great way to guarantee an email’s security, as you don’t always know how well your recipient is protecting their own accounts and devices from cybercrime.
