Hey all, I’m working on an App where some level of email notification is needed. E.g. when a user (with Blockstack Auth, obviously) has created content in the App, there are moments that a email has to be sent to the creator, for example when an other user interacted with it.
I prefer not to store email addresses in the App backend, but I’m uncertain about the possibility to contact the user by email when only the Blockstack ID is known.
What would be the “royal route” to notify App users by email?
