I wrote this guide because most of our clients didn't know Informed Delivery existed — and the ones who did weren't sure how to set it up. I've been mailing since 1998, we've processed over 2.3 million pieces, and everything here comes directly from USPS primary documentation. No speculation. No filler. Just what you actually need to run a campaign.
