Within the Contact Manager module, click on the "Mailing List" button > click on the "Paste from Spreadsheet" button on the tab above.
Open your spreadsheet file > Select the entire column of emails > Copy the selection (Ctrl+c or right-click > Copy).

If your upload doesn't work or you're having problems with the list, make sure that before you import your mailing list your table is clean:
- There should be no separators or strange characters in the cells of the table.
- Each cell in the column should have one email address in it.
- Verify that all emails are in the correct format (email@example.com).
- No “enter” strokes should be made inside the table cells.
