As consumer expectations rise and volatility persists, retail and e-commerce brands must rethink speed, cost, data and reliability when selecting last-mile partners. Here’s what to know: 

1 Reliability Has Replaced Speed as the Primary Metric

As the once-frantic growth of e-commerce has normalized closer to pre-pandemic levels, the hallmarks of good deliveries have shifted. Recent McKinsey research shows that by 2024, speed had fallen to fifth among shopper priorities – down from the top spot in 2022 – behind cost, flexibility and reliability.

“Reliability has quietly become the new speed,” says Joshua Haun, vice president of business development at UniUni, a tech-driven, last-mile delivery company. “Most leaders would rather offer a clear, honest 2–4-day delivery window than promise 1–2 days and miss it half the time. Shoppers forgive slightly longer transit times, but not inconsistency.”

For brands, there’s significant fallout from late and unreliable deliveries regardless of how aggressive the original shipping promise. Missed SLAs and downstream exceptions don’t just frustrate shoppers; they disrupt forecasting, inflate costs and quietly erode brand credibility. These issues rarely stem from demand alone but are rather symptoms of unstable networks.

Instead of prioritizing quick transit, brands should focus on carriers with consistent sortation quality, tight linehaul oversight and dependable final-mile performance. When these foundations are solid, shipping times naturally tighten. In this model, speed becomes the outcome of operational reliability, and not a risky promise that puts brand trust at stake.

2 Rate Clarity Matters More Than the Lowest Price

E-commerce brands often operate on razor-thin margins that are easily eroded by unexpected increases in shipping costs. Unpredictable surcharges – ranging from peak and fuel fees to residential or oversized parcel charges – can add 20–40% to all-in freight costs before returns or exceptions are even considered.

“Retail teams tell me it’s nearly impossible to manage a margin-sensitive P&L when carrier invoices swing week to week because of surprise fees,” Haun says. “And this unpredictability makes planning, promotions and forecasting even harder across their businesses.”

As a result, cost volatility has become a bigger risk than base rates. This has created an opening for agile carriers that optimize shipping through automation and provide greater visibility and predictability. The carrier partnership takeaway here: Ask carriers for clearer, not simply lower, rates. With transparent, all-in pricing, brands gain the ability to forecast accurately, protect margins and make confident decisions across pricing, promotions and growth investments. 

3 Scalable Networks Are the Only Way to Handle Demand Surges

On any given day, the e-commerce terrain can shift without warning. A product goes viral on TikTok, a major influencer sparks demand or a limited-time promotion takes off overnight. The issue: Many legacy carriers aren’t built for sudden surges. Instead, brands are met with capacity limits, lane embargoes or “no guarantee” service just as shopper expectations peak.

This is because traditional carriers often rely on standardized, asset-heavy operations to manage both cost and risk. When demand spikes and capacity tightens, flexibility is limited, which leaves brands to absorb delays, restrictions or added charges.

“There are only so many assets traditional carriers have at their fingertips to surge additional capacity during rolling peaks,” Haun says. “It’s a big reason for these restrictions and charges.”

Diverse carrier networks designed to flex with demand are gaining traction for this reason. Hybrid-national models that combine centralized infrastructure with reliable local delivery partners enable instant scaling without months of planning or costly peak surcharges. When networks adapt in real time, shoppers experience more consistent deliveries and brands maintain control over cost, risk and customer experience.

4 Delivery Reliability Now Depends on Data Integrity

Operational handoffs were once the weakest link in order fulfillment. Today, the greatest vulnerability lies in the data handoff. At scale, last-mile delivery – along with expectations for visibility, connectivity, and flexibility – depends on clean, reliable data and modern technology.

“Many brands still contend with fragmented tracking events, slow or complex carrier onboarding, or legacy endpoints that create integration headaches,” Haun says. “These breakdowns in data translate directly into added exceptions, slower resolutions and more frustrated shoppers.”

When visibility breaks down, e-commerce brands are left with inconsistent tracking and incomplete scans that drive up consumer inquiries and depress NPS scores. As carrier networks diversify, the quality and consistency of data becomes even more critical because every additional handoff multiplies the risk of visibility gaps.

By selecting truly tech-forward, API-first carriers that are fast to onboard and consistent in data quality, brands enable systems to communicate seamlessly. The result is faster exception resolution, fewer support escalations and the ability to make operational decisions with confidence. 

5 In E-Commerce, Delivery Is the Brand

In e-commerce retail, reliable delivery is the brand. Shoppers don’t distinguish between a retailer’s website, fulfillment operation or carrier partners. From click to doorstep, it’s one connected experience and one accountable brand. So, when something goes wrong at delivery, it isn’t the carrier who loses trust – it’s the retailer.

“The right logistics partner doesn’t just support a brand, they strengthen it,” Haun says. “When working with carriers that are committed to protecting the shopper experience, and not putting it at risk, brands see more accurate tracking, more reliable deliveries and happier customers.”

For today’s e-commerce leaders, last-mile carrier selection is no longer an operational decision – it’s a brand decision that directly shapes trust, loyalty and long-term growth.
