You can keep track of your customers' activity in TermSync through a specific filter in the Customer Listing.
1. Navigate to the Customer Listing.
2. Hover over the Filters tab and choose Create new filter.
3. Navigate to the Last Active At filter, and choose the correct parameter for your search such as Any Date to see a complete listing of your customers' most recent login date.
4. In the Choose Columns, you can also drag the Payer Emails and Last Active At columns over into your view, so you are able to review both once you've selected Apply Filter.
