How Datafinder append works

If you have a list of users, customers or prospects, we can append to it. See how it works below.

Step 1: Prepare your spreadsheet.

Your spreadsheet needs to have all data on a single sheet, with only one Input type per column. For example, First Name will be in one column and
Last Name will be in a separate column. The file will need to be saved as a .CSV file.

You will need at least one of the following input types to run an append on Datafinder.

  • Email address
  • Phone number
  • Postal address

Tip: Providing multiple Inputs will yield better results, so please include as many as you can. For the highest level of accuracy, please include First Name and Last Name as Inputs.
