How Bulk Data Appending Works:

Example #1 - Using the Email Append Service

What the Service Does:

Datazapp attaches ("appends") Email addresses closely associated with each of your list's contacts.
(Max 1 Email per row)

Step #1 - File

You'll need a spreadsheet file

This can be a .csv or Excel file (.xlsx or .xls)

Step #2 - Format

Ensure Names and Addresses are in your list.

Names can either be broken into First & Last columns, or together in one column.

Addresses must be separated into 4 columns:
