How to see everyone, no matter when they were added to the list
With SegMetrics, you can see all contacts in your system, no matter when they were added to your list.
To do this:
1. Open a contacts report
2. Change filters to reflect "contact created any time"
3. In the table view below, select contacts
You can see all contacts who came from a specific payment processor by adding the filter "invoice connection equals stripe/drip/etc"
