Append A Direct Mail List

For lists that you’ve originally uploaded via .CSV or Excel files, Postalytics offers an easy way to Append a Direct Mail List.  (This feature is not available for lists that were imported via integrations or the list purchasing tool.)

Please note that the contact records you wish to add to your list must contain the same data fields, and the same mapping as the contact list you’re adding to.  This will ensure that all your contact records on this list have the same layout.  For a quick view of your existing list columns, click the “Field Mappings” link on the list action menu.

The append feature adds additional contact records to a list, it does not add additional data fields to the list.  Do not append new records to a list if there is an active campaign using that list.  Postalytics will de-duplicate your append file, as well as the combined new file, using first name, last name, company. address, address 2, city, state and zip code to ensure that you don’t send duplicate direct mail pieces.  Any duplicates found will be emailed to you in a report at the end of the append process.  

Your append file must be a .csv (comma delimited) or excel file in order to be uploaded.  For more information on how to prepare a file for upload, please visit our Contact List Tips page.

If all looks good, the next step is to map your append file columns into Postalytics.

Required Mapping Fields for Appending a direct mail list

You’ll need to map the required mailing fields, along with any personalization or other fields your existing list contains. It’s simple to click and select the data columns.

When you complete your mapping, you’ll be brought to a confirmation page, where you can review the mapping to make sure it is accurate.

Mapping Confirmation

You can go back and re-map your columns, or click “Import Now” to proceed. The import process will start, and you’ll get an email confirming the process is completed. If the list is large, it can take a few minutes.

Append List being imported

If Postalytics finds any duplicate records, the email confirmation will also include an attached .CSV file with your duplicates listed. We only keep one of the duplicates in your list so that you don’t send the same mailer twice to the same contact.

We’ve made an easy to use tool to help you append a direct mail list to add additional contacts to mail to. If you have any questions or ideas on how to improve Postalytics – we’d love to hear from you!
