Decide What SilverSingles Can Show on Your Phone
Push notifications are app alerts. Email notifications go to the address registered with the account. Current SilverSingles help says email-notification choices are not managed inside the iPhone or Android app, while push notifications can be managed in the app.
Your phone also has its own notification controls. SilverSingles does not decide every lock-screen detail: iOS or Android may control whether a preview appears, whether the app name is visible, whether a sound plays and whether the icon carries an unread badge.
