    Thexyz is a premium email service with exceptional service, features and reliability. While the paid version has far more features than the free service, it is worth every penny if you value your email.

    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.
