AtData's Postal Append, also known as Reverse Email Append, can match name and postal address to 35% - 50% of U.S. email addresses, enabling direct mail marketing to your email prospects or helping you link email subscribers with your catalog or in-store customers. Postal data is DPV certified and NCOA'd once per year.

Use the list of sample emails below to test the endpoint. Each email will return different postal addresses:

[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
📘

Important

The system doesn't provide addresses that are valid but missing an apartment number or secondary address by default. However, you can contact your account manager if you want to receive these addresses. Although your match rate will increase, it's possible that some of these addresses may not be deliverable.
