In Defense of Carrier Diversification: Why AI is Perfect for Modernizing the Ecommerce Shipping Industry and Improving the Delivery Experience

Gone are the days when an ecommerce brand can implement a “set-it-and-forget-it” shipping strategy with a single domestic carrier. The shipping landscape has changed dramatically, and carrier diversification is now a necessity to keep a market edge. The brands evolving with the market are those using AI to navigate a landscape defined by volume caps, labor instability, and the massive USPS cost disruptions we saw in 2025. 

It is hard to believe that we are now almost six years from the start of the pandemic. Before that era, direct-to-consumer shipping had become relatively predictable and comfortable, but everything changed in 2020. When you couple the global pandemic with the logistical demands of mail-in voting for the 2020 Presidential election, seismic disruption rippled across the industry.  

Truthfully, the market hasn’t quieted down since that time. 

Fundamental Changes in the Shipping Industry 

The first major shift we witnessed was the rise of regional and middle-mile carriers. When the major national carriers became overloaded in 2020, existing alternative carriers were forced to accelerate. This included regional carriers handling final-mile delivery, as well as middle-mile hybrid carriers that sorted and injected packages deep within the postal network. Now we’re seeing the strongest of this bunch not only survive but improve significantly.  

Simultaneously, we saw the emergence of Delivery Service Provider (DSP) networks. Advances in technology and surging demand gave birth to these smaller groups of delivery drivers, supported by a management layer and aligned with first- and middle-mile parcel collection entities. 

Largely due to the major cost disruptions resulting from changes at the USPS regarding Parcel Select shipments in 2025, a few of these entities have seen meteoric increases in utilization and growth. However, this rapid scaling has not been without its share of growing pains. 

Why Domestic Shipping Remains Volatile 

Despite these new players, the landscape remains incredibly volatile. We are seeing several factors collide: 

• Capacity Constraints: Carriers are still struggling to meet ecommerce demand; volume caps during peak seasons and unexpected backlogs year-round remain common. 
• Unpredictability: Weather patterns are increasingly erratic, and civil disruption in major metropolitan areas has become a factor. 
• Labor Stability: The labor market in certain parts of the country is less than stable, impacting consistent performance. 
• Market Share Wars: Carriers are in constant fight for market share. The landscape is now so complex that no growing brand has the time to parse out the granular details of every shifting lane. 

Amid this turmoil, there is a desperate need to provide a delivery experience that rises to the image of the brand. It is not, however, a one-size-fits-all approach. What makes sense for recurring subscription shipments may not be appropriate for a one-off order of premium product. Navigating this volatility to provide the proper experience at a specific moment in time is critical. 

Enter AI: Purpose-Built to Solve for the Fractured Ecommerce Shipping Landscape  

AI is quickly becoming the workhorse that will advance our industry because it solves complexity. It handles the obvious factors like speed and cost, but more importantly, it takes the thousands of data points needed to optimize for a single package and gives a clear signal that meets consumer demand. 

Platforms like SelectShip are proving this by providing real-time, optimal carrier selection per package, per service, and per route at the exact moment each package is taped up and labeled. The beauty of this technology is that it gets better over time. It learns from performance across all included carriers for each origin and destination zip code pairing. It then self-adjusts for dynamic conditions, such as weather, that may impact historical results. 

The Result: A Market Edge for Trendsetting Brands 

By leveraging AI-driven carrier diversification, high-growth brands finally have a competitive edge. Brands can turn their time and resources toward managing their business rather than sifting through carrier invoices and rate sheets.  

The results are clear:  

• Route Optimization: Transit times are fully optimized because the system can skip carriers, routes, and shipping lanes that don’t make sense at that specific moment. 
• Simplified Financials: Services like our SelectShip remove the tedium of sifting through static carrier rate sheets. AI can pull an all-in cost, taking into account surcharges, rate variables, and more, to offer a simpler, easy-to-understand pricing model that will please any accounting team. 
• Predictability: On-time delivery is much higher due to routing optimization, ensuring ensures your brand promises are kept. 

The parcel market, like the universe, seeks equilibrium. The pandemic set forth a market expansion that six trips around the sun has slightly tempered. The USPS, seemingly eternal like the asteroid belt, has been an unpredictable source of disruption. Those are the macroscopic factors. 

As much as a constant as disruption are the efforts to harness and control that energy to achieve equilibrium. Diversification through technology is the foundation, but AI to manage selection in real-time, based upon microscopic factors like weather, civil disruption, etc. is the high bar.
