Import History Page
Written By Danny Schaffer
You can view the status of any running imports, as well as the status of any past imports from your Import History page. This is found under:
Contacts >> Import Contacts >> Import History

If you're curious to see which contacts didn't make the cut in one of your past imports, from this page you can also download a list of all the contacts not imported if the import was from the last 7 days.
