The Short Answer
USPS Informed Delivery is a free program that allows eligible residential customers to receive daily email previews of incoming mail before it arrives in their physical mailbox. For businesses, it is a direct mail enhancement tool that lets you add a digital "ride-along" — a color image and clickable URL — to the grayscale mailpiece preview that subscribers receive, turning a single direct mail send into an omnichannel touchpoint. The feature is free to use for business mailers, Informed Delivery notification emails achieve an average open rate of 60.6%, and campaigns are managed through the USPS Business Customer Gateway at no additional cost beyond the postage already paid for the mailing.
Understanding the Core Concept
Informed Delivery operates at the intersection of physical mail infrastructure and digital marketing. When USPS processes letter-sized mailpieces through its automated sorting equipment, it photographs the exterior address side of each piece and stores that image. Residential subscribers to the free Informed Delivery service receive a daily email digest — typically delivered between 7–9 AM local time — containing grayscale previews of all letter-sized mail scheduled to arrive that day.

Actionable Steps
First, audit your current numbers using the calculator above. Second, identify the largest gaps between your actuals and the standard benchmarks. Third, implement a tracking system to monitor these metrics weekly. Finally, review your process every quarter to ensure you are continually optimizing.
Expert Insight
The biggest mistake companies make is relying on generalized industry data instead of their own precise calculations. When you map your exact costs and parameters into a standardized tool, you unlock compounding efficiencies that your competitors often miss.
Future Trends
Looking ahead, we expect margins to tighten as market pressures increase. The companies that build automated, real-time calculation workflows into their daily operations will be the ones that capture the most market share in the coming years.
Historical Context & Evolution
Historically, these calculations were done using rudimentary spreadsheets or expensive proprietary software, making it difficult for smaller operators to accurately predict costs. Modern, web-based tools have democratized this process, allowing immediate, precise calculations on demand.
Deep Dive Analysis
A rigorous analysis of this topic reveals that small percentage changes in these core metrics produce exponential changes in overall profitability. By standardizing your approach and continuously verifying against your specific constraints, you build a resilient operational model that can withstand market fluctuations.
3 Ways to Maximize Informed Delivery Campaign Performance
Design the Ride-Along Image as a CTA, Not a Logo
The ride-along image appears in an inbox alongside dozens of grayscale mail previews. A ride-along that is simply a color version of the mailpiece exterior wastes the attention advantage of the placement. Instead, design the ride-along image specifically as a digital CTA — include a clear action directive, the offer headline, and a visual that creates urgency or curiosity. Ride-along images with explicit CTAs ("Click to Claim Your $50 Offer Before Friday") consistently generate 2–4x higher click rates than brand image-only ride-alongs.
Time the Mail In-Home Date to Maximize the Pre-Arrival Window
The Informed Delivery notification arrives the morning of the expected delivery day. For campaigns where the physical piece contains a time-sensitive offer, consider the psychological effect of the recipient knowing the offer is coming before it arrives — they are primed and have already seen the message. Schedule mail in-home dates for Tuesday through Thursday, when both physical mail response rates and email engagement rates are highest. Avoid Friday and Saturday in-home dates, when the physical piece may sit in the mailbox over a weekend before being acted upon.
Use a Dedicated Landing Page With a Pre-Arrival Offer
Recipients who click the ride-along before the physical mail arrives are demonstrating unusually high intent — they found the digital preview compelling enough to act before the physical piece reinforced the message. Reward that behavior with a pre-arrival exclusive: a landing page that references the mail piece ("Your offer letter arrives today — claim it early here") with the same offer or a slightly enhanced version. This pre-arrival mechanic consistently outperforms generic landing pages because it acknowledges the recipient's specific context and uses the dual-channel delivery as a trust signal.
