In a campaign set, there could be only one gifting or email per guest. If a guest receives gift or notification from one campaign, then they would not receive any more notification/gifts from the rest of campaigns of the same campaign set. Thus, if two campaigns use a custom segment with the same CSV file attached then emails or gift would be sent to the guests only once.
Why were emails not sent to the custom segment guest list for one of the campaign in campaigns set?
