But so far I use one mail on casinos I played including Betfury and have separate email on exchange on which I trade.
That is a very good strategy, unfortunately I do not have that control, I have some emails but to see where I am registered I have to look for it in my inbox and determine which is the email, there are not many emails either, I have 3, one personal, the other for jobs and opportunities that I look for on the web and the other is for social networks where I mix them with the casino registrations or that I am already in a casino, but it would be good to leave only 1 email just for casino registration and only for gambling.
It is good that you can separate your email for many purposes. That makes us use the right email for the thing that we want to do. So having only 3 emails for different things will be enough for you because you can handle with right. The important thing is that you know you will not only use one email for all things. We will determine how many emails we have because we have different things for every email. So we can use the right email for something and let the other emails be used for other things.
