Mailbox.org is a good StartMail replacement because it offers PGP-based encryption (you choose if you want them to handle your private keys or not), and it comes with Calendar and Contacts features that are better than StartMail's. But you have to pay a little to use it. A closer 1-for-1 replacement for Startmail in terms of functionality might be Protonmail, but it has fewer features than Mailbox.org.

Protonmail is probably the best alternative to Startmail at the moment. Both services are fairly bare-bones in terms of functionality, but both also offer end-to-end encryption using the tried and tested PGP standard (unlike Gmail, Outlook.com, Yahoo). Consider Tutanota also, which is very good for the same reason/purpose.
