    Proton Mail vs Hushmail opinions
    pros, cons and recent comments
    JohnFastman

    Hushmail say they're a privacy-oriented webmail, but in 2007 they modified their code for the feds to catch a user's password. Protonmail are based in Switzerland and at the mo there's no evidence of such stuff with them. Hushmail hasn't developed its features in a long time; Protonmail is younger but more active and open source. But it lacks PGP key import-export - that's in the pipeline.

    End to End Encryption, encrypts your entire mailbox, contacts & calendar, what makes account recovery impossible if you forget your password or lost your recovery hash, this is how real encryption works.

    MailDrop is a free throwaway e-mail address. It's temporary. It's transient. It's disposable. It's meant for those times when you don't want to give out your real address. Just give someone any e-mail address in the maildrop.
