Email Clean Up

By bad emails I assume you mean those that are marked as "bad: hard bounce'. You can run a query and pull everyone who has that email status marked as 'hard bounce' and pull them into a group or use it for a mail merge to get CSV file of the names. However at that point you'll have to go through those names and check to see if you have a more updated email account for them. If you can match that group up with an offline list you have of updated email addresses then you can definitely do an upload and not have to do each one manually but you need that data first.

Did that answer your question?
