They seem to have popped up here and there after Lavabit shut down. Silent Circle and Lavabit devs teamed up to create
Darkmail, and Startpage/Ixquick announced their encrypted email service
Startmail a while back, and beta tester accounts were activated sometime in March (for whatever reason, I never activated mine...). Those are the only ones I personally knew about, as I had used their services (Lavabit, StartPage) in the past. Protonmail came up on my radar recently from reading CodeProject News, and was the only one I found that had free accounts. After doing a few
discrete searches, I found a couple more:
Lavaboom:
https://lavaboom.com/en/Free accounts offered. Currently a waiting list for beta accounts. 'Zero-knowledge' key handling, 3-factor authentication (for paid accounts, free accounts have 2-factor)
Hushmail:
https://www.hushmail.com/Apparently, these folks have been around a while. Free accounts are web-interface only, 25MB of storage, and you must login at least once every 3 weeks. Paid accounts have POP/IMAP access and 1-10 GB storage. Not so popular with the hardcore crowd because their terms of service stated they would comply with authorities if you were found to be doing something illegal. Reading through their
TOS today, it looks like they've omitted that language and simply state they will terminate your account.
... and a few services that aren't email providers, but do promise to provide easy-to-use encryption:
Virtru:
https://www.virtru.com/Works with Gmail, Yahoo and Outlook.com, and provides some cool features, such as revoking read permissions after sending (wat?).

Sendinc:
