A Thank You to the USPS Informed Delivery API Team ahead of NPF 2026
In direct mail, rapid innovation tends to attract skepticism, especially from legacy players. We have seen that before. When we founded PebblePost, the early reaction was similar. This is not an industry that rolls out the red carpet for tech companies – except for the USPS.
When we kicked off the build of our Informed Delivery activation feature, one thing we appreciated right away was that USPS has a great team with great docs and materials. The PDFs/PPTs/YAML were all well-dialed in, the onboarding was straightforward, and the ID team is smart, responsive, and creative - everything you want in a partner.
From there, there was no mystery to it. We had one onboarding call, we digested every USPS ID doc out there, and we built. You still have to do the work, obviously, but there was enough public information for a real product and engineering team to understand the API, test against it, and ship against it without drowning in guesswork and assumptions.
People sometimes act as if speed like this must come from insider access to USPS leadership. It doesn't. We're just willing to listen to our customers, read the docs, and build. In our case, that foundation let us move fast on features customers were specifically asking for. Rob and I built our Informed Delivery activation tool together in-house, adding features like real-time tracking and AI image creation and optimization in just a few short months.
So this is a real thank you. We built the product ourselves, quickly, but the USPS ID team made it possible to build it the Stampede way. Thank you to Bernard Fedor, Aisha Khan, A.D. Patel, and Nabil Rahman from the USPS Informed Delivery API team. We're hoping to meet you and thank you in person at NPF.
