The Bouncer allows you to control who gets in your inbox.
When someone new messages you for the first time, their message will appear in The Bouncer. You can then approve, or ignore their message.
If you approve them, they’ll appear inside your Scenes. If you ignore them, their messages will be hidden. The sender won’t know they’re being ignored.
By default, Big Mail will approve everyone who emailed you before you installed the app.
You can approve or ignore someone at anytime by long pressing on their message (right click on Mac) and choosing “Ignore”.
You can disable The Bouncer in Settings and Preferences.
