I have three Excel lists from three different sources (online sign ups, texts, in the office). I am preparing a Mail Chimp email campaign but wanted to clean up the list before uploading it. I am not very savvy with VBA so a formula would be ideal. The formula could get inserted in the last column (E) to distinguish what rows to delete.
The mailing list will include First Name | Last Name | Email | Phone
PROBLEM: Since I combined 3 lists, I have duplicate entries. The only column that I want to use to find the duplicate entries is the Email column as that is unique to each customer I have.
SOLUTION: I am seeking a formula that looks through the Email column, finds duplicate emails and removes the entire row no matter what else is in that row. The attached PNG explains my inquiry visually.
Thank you in advance!
