Notification emails are sent for various reasons and can all be disabled, see below. We may need to contact you in the event of a problem with your profile; (you may have removed your naked pics, you may have uploaded something that's not permitted, we may need to warn you someone who messaged you is a scammer that we've removed, etc.). These messages cannot be disabled.
To disable routine notifications, go to this page. You'll find the 'website emails' section half way down the first column. Tick which notifications you want to receive and untick those you don't. Click the save updates button, bottom left, to complete the change.
