When placing an order for mailing postcards, when do I provide the mailing list?

For mailing postcards, the list goes in at the time you place the order, attached to the job itself.

• Provide the mailing list as an attachment during checkout so it travels with the order.
• Format it as an Excel or CSV file with every name and full address included.
• Use the available CSV template to line up your columns correctly.
• Check for blank rows or missing ZIP codes before you submit, since those slow mail processing.
