I'm working on a number of campaigns that are running simultaneously. And users could potentially be sent down multiple campaigns. As we don't want to overwhelm them with emails, does anyone have suggestions on how to best dedupe users to only send them down one campaign at a time?
Example:
Ad 1 sends users to campaign 1's landing page with white paper offer & lead form
Ad 2 sends users to campaign 2's landing page with white paper offer & lead form.
The two offers are different enough that each has their own nurturing campaign.
User Bob responds to both Ad 1 & Ad 2 to get the different white papers. User Bob is now getting a series of emails from 2 campaigns.
Any suggestions?
