Notifications and emails are equally annoying in my opinion, especially if they are just for their promotion which I don't like because most of the time, these promotion are only made to make you spend more money, even if it is a free money, most of the time you can't withdraw the money.
Hi,
Well, it is not a question of whether they are annoying or not, that is a very personal collateral of each user because in reality sometimes you do not have to enter your mail tray with reading the previous notifications of your smarthphone is enough.
The issue here is the priority of the content of the information that some casinos, not all, give to get it to the user, depending on what they believe is relevant.
It is necessary at the time of a issue know if the "relevant" notifications of a casino are made via email or internal notification, especially those referring to changes in their ToS, that cannot be an assumption, that is why some casinos do mention of how they make their notifications in their ToS.
