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.
