My app sends out instant notifications via text message when something happens. However my app is starting to gain traction and get busy.... which is nice, obviously, but my Twilio bills are getting high.
I've spoke to some users and they have said a text message or an email once a day that collates all of their activity would be better.
I have never ever done any sort of scheduled stuff before, despite building large complex apps.... I've just always managed to avoid it.
Where would I start if I wanted to run something every night at like 8pm that went through all my users and sent them a text (if they have anything to report of course)?
