What is the delivery status for recipients who are part of the control group?

The delivery status for recipients who are part of the control group is classified as ignored. In marketing campaigns, a control group is created to measure the effectiveness of the campaign by comparing the results against a group that does not receive the promotional material. Recipients in this control group are deliberately excluded from the delivery process, meaning they are not sent the email or message being tested. As such, their status reflects that they are not part of the campaign execution, which is accurately represented by the term "ignored." This allows marketers to assess how well the campaign performs by comparing the controlled reactions to those of the active recipients.

The other choices do not align with the nature of a control group. "Delivered" would suggest that the recipients received the message, which contradicts the purpose of having a control group. "Bounced" implies that there was an attempt to deliver a message, but it failed; however, since the control group does not receive messages, this status is also inappropriate. Lastly, "Pending" would indicate that the status of these recipients is undetermined, but again, they are not included in the campaign flow at all, making this status inaccurate.
