Specialty Mailing Programs: How to Save on Shipping

Written By: Will Lubaroff

Shipping and postage can make or break the ROI of a print program, especially when you are mailing on a tight schedule or trying to stretch a fixed budget. The good news is that you usually have more levers than you think. With the right specialty mailing strategy, you can reduce postage spend and keep production moving without sacrificing quality. 

Start With the Real Goal: Lower Total Delivered Cost 

It’s easy to focus on postage alone, but the smarter metric is total delivered cost. That includes: 

  • Postage or carrier fees 
  • Prep and handling 
  • Freight and entry costs 
  • Waste from undeliverable records 
  • The cost of delays or inconsistent timing 


The most effective mailing strategies reduce cost across all these areas. In many cases, the biggest savings do not come from promotions; they’re impacted more significantly by how the mail is prepared and where it enters the postal network. In simple terms, better logistics equals better pricing. 

The Foundation: Presort, Clean Data and Postal Readiness 

Before moving into specialty programs, it is critical to get the basics right. Creating mail files that are clean and properly structured sets your entire mailing operation up for success. At a minimum, strong mailing programs include: 

  • Address validation and standardization 
  • National Change of Address updates 
  • Duplicate removal 
  • Proper segmentation for presort 

 
Presort is a key cost driver, but it is important to understand what is and is not within your control. USPS sets strict requirements for how many pieces must go to a specific location to qualify for deeper presort levels, so most mailers cannot improve their presort simply by cleaning up or adjusting their lists.

In practice, the primary way to achieve better presort rates is by participating in a commingling program, where your mail is combined with other jobs to meet those thresholds and unlock additional savings. 

Program 1: Commingle for Letter-Size Mailings 

Commingling is when multiple mailers combine their pieces into a single, larger mailing. That combined volume allows access to better presort tiers and workshare discounts. Commingling is often used for: 

  • Smaller individual mailings that would not qualify for deeper discounts on their own 
  • Programs that can tolerate shared scheduling windows 
  • Mailers looking for incremental savings without changing format 

Program 2: Comail to Unlock Bigger Presort Discounts 

Comail follows the same concept, but it is designed for flat-size publications. 

Instead of mailing one publication by itself, multiple pieces are combined into a shared pool. This increases total mail volume, which allows the group to qualify for deeper presort discounts. From an operational standpoint: 

  • Mail files are combined into a shared pool 
  • Pieces are presorted together 
  • Final pallets are built for optimized distribution 


This approach works best when mailing flat-size publications such as magazines or catalogs. 

When Comail is a strong fit 

  • Flat-size pieces that benefit from volume-based discounts 
  • Programs with predictable schedules 
  • Mailers comfortable aligning production to shared mailing pools 


In many cases, the added scale results in lower postage and more efficient entry into the mailstream. 

Program 3: Drop Shipping With USPS 

In mailing terms, drop shipping refers to entering mail deeper into the postal network rather than introducing it locally. 

Instead of sending all mail through a single origin point, mail is transported closer to where it will be delivered. This reduces the amount of work USPS needs to perform, which leads to discounts. This is often called destination entry or Plant Verified Drop Shipping. 

Key advantages include: 

  • Lower postage through workshare discounts 
  • Faster in-home delivery in many cases 
  • More predictable delivery timing 


This approach becomes more valuable as postal pricing increasingly rewards operational efficiency. The closer mail is entered to its destination, the greater the potential savings.

It is important to evaluate each job carefully by coordinating with your presort provider to confirm whether it qualifies for savings, especially as recent rising freight costs have reduced the overall value of drop shipping in some cases. 

How to Choose the Best-Fit Program for Your Project 

Each program has strengths. The right choice depends on your specific mailing profile. Use these questions as a starting point: 

1. What format are you mailing? 

  • Letter-size: evaluate commingling 
  • Flat-size: evaluate comail 
  • Products or kits: evaluate fulfillment and carrier options 


2. What is your volume? 

Higher volume increases eligibility for deeper presort levels, while lower volume may benefit from pooled programs. 

3. How flexible is your schedule? 

Pooling programs require alignment with shared timelines. Independent entry offers more control, but may limit savings. 

4. How clean is your data? 

Strong data unlocks discounts, while weak data increases costs and risk. 

In many cases, the best results come from combining multiple strategies rather than relying on a single solution.
