3. Click on the Merge Lists option from the Contact List Activities block in the details page for the list

Notes:

• The merge is usually processed within 30 minutes but this will depend on the list size and details.
• Benchmark Email automatically scans and removes duplicate email addresses when you merge two lists. If an email addresses appears in both your lists, the newly merged list will only contain that contact once.
• You can also move or copy contacts from one list to another.
