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?
Does that mean it can only be retrieved at the moment a Blockstack user interacts (logs in or posts for example) with the app? Meaning, if I want to be able to notify that user e.g. a month later, I cannot fetch it just then?
Please note that basically I’m not interested to know a users email address for all thinkable reasons of privacy, security, etc. Though I understand it’s probably not a core functionality of Blockstack, but it would be awesome if there’s an API to send notifications through Blockstack for users that are using an app.
Lastly, email seems to be optional so to be able to send notifications I probably need to users to submit their email in our app anyway?
