The easiest way to see how many email addresses have been added by ResaleAI is to log in to your Constant Contact account.
Click on Contacts / Reports.
You will get a screen like this:
The number at the bottom left of the screen labeled 'Other Apps' should be the number of addresses that ResaleAI pulled from DRS and added to Constant Contact. However, if you have set up other apps to add email addresses, those addresses could be mixed in.
If you want to check what list the email addresses are going to, go to Contacts and select the list. Then click the gear icon at the top right and choose the view "Name, Email, Date Added, Source"
Then sort by Date Added.
