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.

Proton is not confidential at all, because it is under the influence of the EU. The best thing you can find for anonymous messaging and file sharing is the Utopia ecosystem (U.IS)

Mailfence offers more functionality than Proton mail with Calendar, Document, Chat, and Group functionality. Moreover, the price is much lower than other competitors.

Excellent integrated business features. Works as a webmail client for many e-mail addresses hosted from different servers/locations (the paid versions). Perfect alternative to ProtonMail for business users!

Comments about Mailbox.org as a Alternative to Proton Mail
Almost everyone thinks Mailbox.org is a great Proton Mail alternative.
John Fastman
Mailbox.org is a partial replacement for Protonmail. It offers a fully functional email solution (email, calendar, contacts), but with the added benefits of PGP encryption support (you can handle the keys or let them do it). It also allows you to send links to people who don't use PGP if you want to send private messages. For the encryption, it's a bit like Protonmail. For everything else, it's like a privacy-respecing Gmail alternative.

John Fastman
Posteo could be a good Protonmail alternative. It offers email encryption in a similar way: Posteo's people, government surveillance and successful hackers won't get into your email content. It also offers a calendar feature, which protonmail users have been crying out for for years.
