You can easily find out how many subscribers from your latest import were undeliverable on the Manage Subscribers page of your account.
Step By Step Instructions
- Under the "Subscribers" tab, click Manage Subscribers.
- You will need to add three select fields, totaling four select fields. You can add select fields by clicking on the "plus" button. Each time you press the "plus" button, a new select field will be added.
- Here, you'll want to set your first "Select Field" to "Add Method" is "Imported."
- The next two select fields should identify the date of the import. The first should be "Date Added is on or before (Import Date)", and the second should be "Date Added is on or after (Import Date)."
- Finally, set the last select field to "Stop Method is Undeliverable", then click "Search." This will pull up a list of every undeliverable address from that import.
If you want to compare this against the number of total subscribers that you imported, you can find that number either by not using that last select field above, or by simply checking the bottom of the Import page.
