What is the difference between a warning and an error message in EasyPost Connect?

When preparing shipments, the portal may detect certain issues that are not entirely in order. In such cases, you will receive a warning. If you receive a warning, your shipments will still be printed and sent. Unless the operator decides that bpost will not be able to process the shipments because of these issues. In that case, you will receive an error message. For example, if important information is missing, such as house number, postal code, or city, the operator will generate an error message. As a result, the shipments will not be processed because bpost will not be able to distribute them.

If registered mail receives a warning or an error message, it will still be processed due to the urgency of such mail.
