If you create a new Contact list by combining two or more lists, you can remove all the extra contracts with the same email address across all the included lists. In this way, you can make sure that no contacts receive the same email from you more than once.
When you remove duplicate contacts from a list, the duplicates are only removed from the current list. All the contacts are still available in other lists and in the contacts database.
To find and remove duplicate contacts from a list:
- In the List Manager, open the list that you want to remove duplicates from.
- On the list page, click Actions and then click Find/remove duplicates.
A notification appears telling you how many duplicate contacts that were remove from the list.
- Save your changes.
