Background campaign caused list to receive two emails from different programs
I recently created an email campaign nested in a default program. The leads in this program all received the email.
I have a completely separate nurture campaign and somehow these leads received the first email from this program through a background campaign. I have never had this issue and am trying to find out more about background campaigns and how I can prevent them from causing leads to receive emails or join programs I don't want them to. Any help or information is greatly appreciated--thanks!
