How to send a push notification to a guest user?

[Patrick_Paul]

I have an app that does not require sign-in.  This is deliberate for very good reasons that I won't go into here.  How can I generate push notifications for the "guest" users of this app?

If your intention is to send a message to all the users at once, there is a Broadcast Notification feature found in the Manage tab under Deploy.

Otherwise...Not possible with out of box features. 

You could request that users provide their email addresses - either in UserSettings or in a table entry - and then use that to send the Push Notification to them.  Just be aware that with an unauthenticated user, some WILL provide bogus email information.  Additionally, the app is subject to typo's - which happens frequently with email addresses.

I hope this helps!

Let's say I was wanting to send a message to all users at once, but I want a user to be able to initiate it, not me as the app creator.  I'm struggling to figure out how to do that.  In a "normal" programming language, I'd loop through all rows in the users table... Is there some way to accomplish this without *me* doing it manually when needed?
