Mailing List File Types

You can upload .csv, .xls, .xlsx, .txt or vCard files to Mailing Online Pro and Easy Letter Sender. Every mailing list should have a header row.  A header row gives titles to each column in your list, such as Name, Address, City, State and Zip. Each piece of data in your address should be entered into a separate column.
