I want to understand behavior & demographics (open rate, location/country, click rates, etc.) from specific segments of users (e.g. subscribers we've recently acquired through facebook ads).
Hello @Jackie Please advise for us what having this information will enable you to do. Unlike with perhaps other email service providers you may be used to, Maropost's segment memberships are dynamic. That means any given segment's membership can and will change from second to second. And the data for the members within any given segment can and will change from second to second. Having this dynamic nature, what actions will having this information allow you to do? Have you also taken a look at the Customer Engagement report (a.k.a. "eRFM Report").
This report enables you to identify cohorts of interest and to automatically create segments for any cohort. Once we understand your use case, perhaps we can arrive at the appropriate solution to meet your needs.
