Last mile delivery is the riskiest step in e-commerce shipping, and it decides whether a customer comes back. In this final stretch, parcels get lost, damaged, or stolen. Merchants can't control the truck, but they can control how much they know about each shipment and how fast they respond when one goes wrong. Shipping insurance reimburses the loss, so a failed delivery doesn't become a refund you pay out of pocket.

‍

What is Last Mile Delivery?

Last mile delivery is the final leg of a shipment. The parcel leaves a local facility and reaches the customer's door. Carriers usually run this leg themselves, but some hand it to another carrier.
Hybrid services show how that handoff works. FedEx Ground Economy (formerly SmartPost) and UPS Ground Saver (formerly SurePost) move a parcel through the carrier's own network, then pass it to a local carrier for the final stretch. For FedEx, that local carrier is almost always USPS. UPS has shifted between its own drivers and USPS over the past two years.

Benefits and tradeoffs of hybrid last mile services

For carriers

U.S. parcel volume reached 23.1 billion in 2025, up 3.3% from the year before, according to the Pitney Bowes Parcel Shipping Index. Pitney Bowes forecasts 31 billion by 2031. Carriers need a cheaper way to reach every address, and a hybrid handoff delivers one. USPS already runs routes to nearly every residential address, so a carrier that hands off a light parcel avoids sending its own truck down the same street.

For merchants

Hybrid services suit a specific kind of shipment. FedEx describes Ground Economy as built for low-weight, low-value, nonurgent residential deliveries. For that kind of order, the benefits are real:
• Lower cost. Handing the last stretch to a local carrier costs less than a full residential Ground delivery, which lets merchants hold down shipping prices.
• Weekend delivery. FedEx Ground Economy delivers Monday through Sunday.
• Wide residential reach. FedEx advertises full U.S. residential coverage for the service.

‍
The tradeoffs are just as specific:
• Slower transit. FedEx Ground Economy typically takes 2 to 7 business days in the contiguous U.S.
• Weight limits. FedEx suggests 1 to 10 pounds for the service and caps packages at 70 pounds.
• Less control after handoff. Once a local carrier has the parcel, a merchant has fewer ways to hold, redirect, or trace it.
• Contiguous U.S. only for UPS Ground Saver. Alaska, Hawaii, and U.S. territories fall outside the service as of 2025.

‍
The tradeoffs can be significant for high-value shippers. A $2,000 order doesn't belong in a service built for light, low-value, nonurgent parcels, and the reduced visibility after handoff makes a lost package harder to find. 

Challenges for the Shipper

The final stretch costs more per package than any other leg of the trip. It also carries the most surprises: missed routes, failed attempts, and parcels left on a porch. Estimating last mile cost is hard because each of those surprises adds its own charge. Here is where shippers run into trouble, and what helps.

‍

Route Control

A driver without a planned route takes longer to deliver. Many carriers now use route-mapping software to cut those delays. Shippers can't pick the driver's route, but they can pick carriers and services. Claims data shows which lanes and carriers produce the most losses, so a merchant can move volume away from a weak lane instead of guessing.

Customer Issues

Incomplete addresses, remote locations, and absent customers force redelivery attempts. Address validation at checkout catches bad addresses before the label prints. Pickup points and lockers give customers an option when nobody is home.

Package Theft and Unattended Delivery

A package left on a porch has no protection until someone walks outside. Security.org's October 2025 survey of 3,307 U.S. adults estimates that 37 million packages were stolen over the past year, at roughly $222 each. The estimate extrapolates three-month survey answers to a full year, so treat the total as an approximation. The per-package value is the figure to compare against your own average order.

‍
Signature requirements put someone at the door at the moment of delivery. If nobody signs, the carrier holds the package or tries again instead of leaving it unattended. Higher-value orders warrant that rule even when it adds a day.

Tracking and Visibility

Customers expect a notification when a package ships and another when it arrives. When a parcel shows up damaged, late, or not at all, they turn to the shipper, not the carrier. Real-time tracking cuts the "where is my order" emails. An integrated platform, such as Cabrella, connects shipping and insurance through an API, so transactions, claims, and invoices live in one place.

Shipping insurance for lost or damaged orders

A lost or damaged order turns into a negative review fast. Third-party shipping insurance reimburses you for the loss, so you can send a replacement or refund right away instead of waiting on a carrier claim.

‍
Cabrella also works on the step before the claim. Its package recovery team makes every effort to locate a missing parcel before a claim gets filed, which keeps your loss history clean and your rates lower.

Alternatives Gaining Ground with Shippers

The carrier landscape has shifted. The Pitney Bowes index reports that Amazon Logistics overtook USPS as the largest U.S. parcel delivery provider in 2025, with 6.9 billion parcels. Alternative carriers more than doubled their share of parcel revenue, from 3.4% in 2024 to 7.2% in 2025. Merchants now have more last mile options than a few years ago, and each one brings a different risk profile.

‍
• Regional carriers and last mile startups. Companies such as OnTrac, Veho, and UniUni handle the final delivery in specific regions or lanes, which gives merchants a second option when a national carrier underperforms.
• Crowdsourced and gig delivery. Carriers and platforms use independent drivers to deliver parcels, often faster than a traditional route and on a window the customer picks.
• Pickup points and lockers. Retail stores and lockers act as distribution points. Customers collect parcels on their schedule, so nothing sits on a porch.
• Drones. Drone delivery has moved past trials. Walmart reported passing 1 million drone deliveries in May 2026, with partners Wing and Zipline. The payloads are small, though. Wing's drone carries under 3 pounds and Zipline's up to 8 pounds, so drones serve light, local orders rather than most e-commerce parcels.

‍
More carriers means more variation in how packages get handled. A merchant that ships through three carriers has three different loss patterns to track, and an insurance program that works across carriers keeps one set of claims data instead of three.

‍

Conclusion

Last mile risk starts before the package leaves the dock. The service you choose, the address you validate, and the signature rule you set all decide how the final leg goes. Most merchants set those rules once and never revisit them.
They should. Claims data shows which carriers, lanes, and order values produce losses. Merchants who read it can change a service level or a signature rule before the next loss, instead of after. Pair that with a recovery team that tracks down missing parcels before a claim gets filed, and the final leg stops being a guess.
