I am creating a mass marketing application where I can send coupons to all of my subscriber base which can be a few millions people and I should be able to send coupons through out the day as many times I want.
So,my confusion is will my mission be hindered by any kind of quotas like amount of push notifications in a day/week/month on these popular services.Also,is there any possibility of my app getting banned for sending so many messages to people.
My app won't spam the user with irrelevant stuff and the app will ensure that all the coupons sent,will be of interest to the user.
