Next, we need to map the columns in the file to the appropriate “attribute” in the email program.
For example, look at the image below. The EMAIL column is already being linked with the EMAIL contact attribute, however the LASTNAME and FIRSTNAME are not. If you click the contact attribute dropdown and then select LAST_NAME, you will link the LASTNAME column on your contact list with the LAST_NAME contact attribute.

Next, simply name your list and that’s it. You contacts are now in your email program.
