To switch off email notifications, simply follow the steps below:
Log in to your profile, click on “Settings” in the menu list on the left side right underneath your profile picture/icon.
You can change your email preferences under 'Notifications'. There are four main categories of email notifcations, in each, you can find specific email types. You can easily choose which you'd like to receive by leaving the slide button 'On'.
If you wish to stop email notifications in general, switch all the slide buttons in all categories to 'Off'. Or you can simply click on 'Unsubscribe' in any emails you receive from MySecretAffair. That will lead you to your 'Settings' page, and you can do the rest yourself.
