Your contacts that are in your CCB Groups and Saved Searches are not retrieved into BombBomb until you send to a CCB list. Once you have sent an email to a CCB list the BombBomb app will load those contacts into that List. The same is true for scheduled emails. With scheduled emails the contacts are retrieved at the time the email is scheduled.

The BombBomb app only retrieves the contacts that are in your CCB groups and saved searches. You cannot update, delete or create new contacts in CCB from within the BombBomb app. If contact information or group members change in CCB then that information is updated in BombBomb the next time you send to that list.
