I am required to sent notifications to both website users as well as app users. Both website users would see notifications in their messages inbox but app users get the advantage of getting a push notification. I already have a filter built over the backend field based on user preference (like gender, nationality, their actions) and time based activity. Based on this backend filter I would get a large list and I was planning to sent out push notifications using named users for those in the list that have app installed. Is this the right way to do this.
What are the better options. I also read about an API to upload a CSV list of Named Users. Is this a one time upload. Since I might want this notification for a certain time period.
I might have to set up a push notification for users who have opened the app for the first time, or even just organically opened the app in the last 7 days, 30 days, or even just yesterday. How can I then get this notification so I can display in the website/app inbox?
