    Tutanota is end-to-end encrypted, as well offers 1 GB mail storage on free plan. The pro plans are cheap compared to protonmail, so it's better for low budget users

    Tutanota has historically been a lot more transparent, and arguably has been more honest about issues and plans

    I use both, ProtonMail is more secure but also more expensive and not as user-friendly. You cannot beat the price of Tutanota for service they provide.

    Zoho Mail vs Proton Mail opinions
    This alternative is disputed. Zoho Mail is still a legitimate alternative to Proton Mail, but it might have issues that some users think are important.
    JohnFastman

    The whole point of switching to an encrypted email provider (Protonmail, Tutanota, etc.) is to avoid the prying eyes of the company's techies, government surveillance and hackers to breach the servers. Zoho Mail doesn't encrypt your email, so it doesn't offer that security or privacy.

      Criptext vs Proton Mail opinions
      Almost everyone thinks Criptext is a great alternative to Proton Mail.
      Guest

      Even thought Proton Mail is a good privacy focused email, it still holds both your emails and your keys on their servers. Regarding ownership, Criptext gives the user ownership over their keys, which reside only on the user's devices. It also uses Signal Protocol for encryption which I personally like better than just using pgp.
