@bthylafh @Horizon_Innovations @protonmail @Tutanota @hyploma IIRC, elude.in is one of the more versatile ones. It can send email from elude.in to both clearnet & onion recipients, it can receive email via onion or clearnet (you have two address domains), and the UI is accessible by either onion or clearnet. Onionmail may be the same, but most services have on limitation or another.
