Troubleshooting Tips: Uploading Contact Target or Suppression Lists

Having issues uploading your suppression or target contact list? Here are some tips.

  • Make sure you have downloaded the correct template for your list.
  • Delete any hidden columns that might be in your spreadsheet.
  • Make sure the header titles don’t accidentally get changed in the process of cutting and pasting your information - they need to be exactly as they are in the template. 
  • If your list has separate columns for first and last names, you can use the formula =A2&" "&B2 to combine them into a new column. You will then need to copy the new column of first & last names and paste the values only to get rid of the formula. Shift + F10 + V is the shortest way to use the Excel “Paste special - values only” dialog. Now you can delete the columns with the separate first and last names.
  • If your list has some contacts with phone-only, and some with email-only, you’ll need to create two separate lists - one for the contacts with phone, one for the contacts with email. You can upload multiple lists for the same event.

Required fields include: 

  • Name
  • Company
  • Phone or Email (or both)
  • State
