We work in a small fashion e-commerce app Quickly we noticed that app notification is a good way to keep customers engaged, raise conversion rate, tell all users about news & offers , get more sales and reach customers that forgot about the app.
However we are not sure about the optimal amount of notifications per week.
I was searching around how other shops and competitors do it, they do nearly daily notification. In my opinion this is overwhelming and wrong, personally I had blocked notifications completely of apps that bother me everyday with notifications
So what is the amount of days that we should push a notification with the most convenient frequency, timing for the customers, so they won't get annoyed and block notifications and even uninstall the whole app..
