    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.

    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.
