compare a block list against the user lists

Hello, is there a possibility to compare a block list against the user lists.

Would you like to import a blocked CSV file and then delete it from the lists !?

Thank you

Hi,

Follow these steps:

Create a new list
import your CSV and subscribe these users to your new list (existing users will be added to this list iof the mail address matches)
Run a mass action to delete all users subscribed to your new list
Delete your new list
