Your leads will be imported in the background. It can take between 5 and 10 minutes to complete a larger import. Please be patient. You will see a progress bar at the top of your page indicating the progress of your import. You will receive an email notification that your import is complete when its done. The email will include a summary of the imported data. Once it says the import is complete, please re-fresh the Leads Tab to see your newly imported Leads.
