Don't Sweat the USPS Postage Increases: How a Smart Postal Strategy Cuts Your Mailing Costs
Every year, like clockwork, the USPS announces a postage rate increase — and every year, direct mail marketers brace for higher costs. However, the old adage "postage is postage" simply isn't true anymore. The rate you pay isn't fixed. It's the result of decisions — how clean your list is, which mail class you choose, and how your mail is sorted before it ever reaches a mailbox. Get those decisions right, and you will ensure you are paying the lowest rate. Get them wrong, and you're paying more than you need to on every single piece. Below is the postal strategy we run on every mailing list to make sure you're paying the best possible rate for your campaign, no matter what the USPS does with pricing this year.
Step 1: Data Hygiene — Stop Paying to Mail Addresses That Don't Work
Before a single piece goes out, your list needs to be cleaned. This isn't a nice-to-have — it's the single biggest lever for avoiding wasted postage.
CASS Certification. We run every list through USPS CASS (Coding Accuracy Support System) certification, which validates and standardizes each address against USPS records. Any address the USPS can't deliver to gets flagged and removed before you pay a cent to mail it.
Duplicate Removal. Next, we scan for duplicate records. Sending the same piece to the same household or business twice doesn't get you a second chance at a response — it just doubles your postage for no additional return.
NCOA Processing. Finally, we run your list through the USPS National Change of Address (NCOA) database. This identifies anyone on your list who has filed a change of address with the USPS and automatically updates their record with the new address. That means your mail piece follows your customer — instead of landing in the mailbox of a stranger who moved in after they left.
Together, these three steps ensure every piece of postage you pay for is actually going somewhere.
Step 2: Mail Class Selection — Matching Speed to Strategy
Not every campaign needs to arrive tomorrow, and paying for speed you don't need is one of the most common ways businesses overspend on postage.
First Class Mail delivers in roughly 1–4 days across the United States. It's the right call when timing is critical — invoices, time-sensitive offers, or anything tied to a specific date.
Marketing Mail (Bulk Mail) takes longer — typically 5–12 days across the United States — but at a significantly lower cost per piece. For campaigns where the calendar has some flexibility, this is where the real savings live.
We work with you to understand your campaign's priorities and time-to-market needs, then recommend the mail class that fits both your deadline and your budget.
Step 3: Sortation — Finding Every Available Discount
Once your mail class is set, the next question is how the mail gets sorted and entered into the USPS network — and this is where postal strategy really pays off.
Destination Entry Discounts. We analyze your list to identify opportunities for destination entry, which allows us to bypass local USPS submission and enter your mail closer to where it's actually headed. Skipping steps in the USPS transportation network means a lower postage rate for you.
Co-Mingle Consolidation. If your list has a broad geographic footprint and destination entry isn't a fit, we look at co-mingling — consolidating your mail with other campaigns to reach better sortation discounts than a local submission would get on its own. We compare the local USPS rate against the co-mingle rate and apply whichever option saves you more.
The Bottom Line
This is the postal strategy we apply to every campaign, every time: clean the list, pick the right mail class, and sort for the best available discount. It's how we make sure that when USPS rates go up, your costs don't have to follow — because "postage is postage" was never really true. Strategy is what determines what you actually pay.
Frequently Asked Questions
What is CASS certification and why does it matter?
CASS (Coding Accuracy Support System) is a USPS program that validates and standardizes mailing addresses against official USPS records. Running your list through CASS removes undeliverable addresses before you pay postage on them — directly reducing wasted spend.
What is NCOA processing?
NCOA (National Change of Address) is a USPS database of address changes filed by residents and businesses. Processing your list against NCOA updates records for anyone who has moved, so your mail follows your customer instead of going to the wrong address.
When should I use First Class Mail vs. Marketing Mail?
Use First Class Mail when timing is critical — invoices, time-sensitive offers, or date-specific campaigns. It delivers in 1–4 days but costs more. Marketing Mail (Bulk Mail) takes 5–12 days but costs significantly less per piece, making it the right choice when your campaign has scheduling flexibility.
What is destination entry and how does it save money?
Destination entry means dropping your mail at a USPS facility closer to where it's being delivered, bypassing steps in the USPS transportation network. Because the USPS handles less of the logistics, they charge a lower postage rate — the savings can be meaningful on larger mailings.
What is co-mingling?
Co-mingling consolidates your mailing with other campaigns to achieve better sortation discounts than a standalone local submission would qualify for. We compare the co-mingle rate against the local USPS rate and apply whichever saves you more.
