Friend Ejector is a Facebook app that lets you remove the deactivated, inactive, or unengaged users from your Facebook profile.

You can view the users who have been removed, and you can add all of the people back to your profile.

This is not only for marketing purposes, but it also helps you save money. Many people keep their friends list full of inactive and deactivated people, and if they reach out to them on Facebook messenger or by email, they are likely to get little or no response. This increases your cost for the messages that you send out.
