  • What format should I use to upload my mailing list?

    CSV (Comma Separated Value) and Excel files are accepted.

    File Upload Requirements:

    • The columns in your upload files can be sorted in any order. Our tool allows you to match your formatted columns to the appropriate fields in our system.
    • Your mailing list must include the following as separate columns: first_name, last_name, address, city, state and zip. 
    • Convert your .XLS spreadsheet to a Text .CSV (Comma Separated Value or Comma Delimited) or a Windows Text .CSV (for MAC users). Go to File, then Save As and change the file type to .CSV. Please note that addresses are limited to three (3) lines when printed: Name, Address and City/State/Zip.

  • What if the zip code only shows 4 digits?

    The zip code likely contains a leading zero and will show only 4 digits on the Mailing List. No adjustments are necessary as our system will automatically correct the zip code format prior to mailing.

  • Can I download my mailing list?

    Yes, log into My Account to download a stored Mailing List.

  • Can I receive a sample of the print?

    Yes, you may add your own address to the mailing list to receive a sample of the print if desired.

  • What if the addresses on my mailing list are invalid and my direct mail cannot be mailed?

    Our system will automatically scrub your Mailing List for invalid addresses. The customer is ultimately responsible for uploading valid mailing addresses.

  • Can I save or store my mailing list?

    Yes, we can store your mailing list for approximately 6 months in My Account. However, storage is not guaranteed due to limited storage or during times of high volume orders.

    Unfortunately, we do not store any list that was either uploaded or inputted into our system for holiday cards. If you wish to mail holiday cards often, we recommend creating a CSV file of your contacts that can be uploaded for each order. The required fields for this file are First Name, Last Name, Address, City, State and Zip Code.

  • How long is my previously purchased list saved in My Account?

    Your previously purchased list will be saved in your My Account for approximately 6 months from the date purchased.

  • Can I use Mailing Services for any product?

    No, Mailing Services is only available for Postcards (4.25" x 5.5", 4" x 6", 5" x 7", 5.5" x 8.5" or 6" x 11") and Greeting Cards (4.25" x 5.5" or 5.5" x 8.5", folded).

  • Can I have duplicate addresses in my mailing list?

    No, please avoid duplicate mailing addresses in your Mailing List. Overnight Prints will attempt to remove duplicate entries prior to mailing.

  • Will my mailing lists remain confidential?

    Yes, your mailing list remains confidential. Overnight Prints does not share or sell your mailing lists.
