Informed Delivery Mailer Onboarding Guide

This is the Mailer Onboarding Guide to assist in the initial set up to submit Informed Delivery Campaigns via eDoc in the CAT (Customer Acceptance Testing) environment. This covers how to set up a CAT Business Customer Gateway (BCG) account and permit for testing Mail.dat and Mail.XML eDoc submissions that include campaign data to create Informed Delivery Campaigns via PostalOne!

All new BCG accounts will need to be verified and approved by the CAT Help Desk before they can be used for testing.
