How to Remove Duplicates in Apple Mail
If your Apple Mail client contains duplicate email messages, you can download and install a Mail add-on that automates the process of identifying the duplicates. When you run the script, duplicate messages are identified and copied to a folder on your desktop. You can then review the messages and delete one of the duplicate copies. Run the script on one mailbox folder at a time in the Mail client to quickly clean up duplicate emails.
