> Push notifications can be considered a form of recommender system

No. Push notifications are notifications. They have to notify you about something that has happened that concerns you, personally. Like if someone sent you a message, or commented on your post, or liked your content. A sale in a store, or an app update being available, or it being a certain time of day, does not, ever, under any circumstances, qualify as a reason to send a push notification. No matter how cringe-cutesy it is and how many emojis it contains.

Bulk push notifications in any shape or form Just. Should. Not. Be. A. Thing. Period.
