I understand you may be getting too many emails from the website. You have x2 options to rectify this, you can manage your email settings in your profile so you get notified based on what you want to see. Simply go to profile and settings to see the available options.
Secondly, on every post you have the option to follow / unfollow. If you unfollow then you won't get any emails about this post.
If you do intend to turn off all notifications it is important you regularly check the website yourself, just simply to ensure you keep up to date with any activity related to your competitions / fixtures. Attached some screenshots so you see the relevant options.
Any questions, just shout.
