There is requirement to restrict a user to get one email per delivery campaign.
the solution what i have currently working is to use typology rule as marketing do not have to worry about it to put code in each campaign to check for it. we have multiple delivery in one single campaign
what happening the filter typology is currently removing all the recipient who have been contacted that particular delivery template. Unable to get the current delivery into typology as well as association of recipient with the current delivery template.
Any help appreciated.
