Direct Mail Postage and Mailing Costs
Four cost components drive every direct mail campaign. Understanding each one helps you budget accurately and find savings without cutting the wrong corners.
What Affects Direct Mail Cost?
Every direct mail invoice has four line items: printing, mailing list, mail processing, and postage. Some campaigns skip the list cost (EDDM), and some skip processing (if you supply a clean list). But understanding all four components gives you full control over your budget.
At Catdi Printing, we itemize every cost so there are no surprises. Postage is always billed as 100% pass-through — what USPS charges us is exactly what you pay.
Printing Cost
- Mail piece size and paper stock
- Quantity ordered (larger runs = lower per-piece cost)
- Color coverage and coating
- Single-sided vs. double-sided printing
A 6×9 postcard at 5,000 pieces typically costs $0.07–$0.12/piece printed.
Mailing List Cost
- List type (consumer, business, property, occupant)
- Number of demographic selects applied
- Record count
- One-time vs. multi-use license
Consumer lists run ~$30–$75/thousand. B2B and specialty lists run $50–$150+/thousand.
Mail Processing Cost
- CASS certification and address standardization
- NCOA update (removes moved/undeliverable addresses)
- Deduplication (removes duplicate records)
- Variable data printing and addressing
- Pre-sorting by carrier route for postage discounts
Processing typically adds $3–$12 per thousand pieces — a small cost that protects your entire print and postage spend.
Postage Cost
- EDDM flat rate (~$0.21/piece — no addressing required)
- USPS Marketing Mail / Standard Class ($0.25–$0.33/piece)
- First Class postage ($0.51+/piece, forwarded and returned)
- Presort discounts based on carrier-route sorting level
Postage is billed as 100% pass-through with no markup from Catdi Printing.
Why Postage Is Billed as Pass-Through
Some mail vendors mark up postage as a profit center. At Catdi Printing, postage is billed as a direct pass-through — 100% at the USPS rate, with zero markup.
This matters because postage is often the largest single cost in a direct mail campaign. You'll see it as a separate line item on your invoice, billed exactly at what USPS charges. Our revenue comes from printing, processing, and service — not from inflating your postage.
How to Lower Mailing Costs
Print higher quantities
The per-piece printing cost drops significantly as quantity increases. Going from 1,000 to 5,000 pieces can cut printing cost by 30–40%.
Use USPS Marketing Mail instead of First Class
Unless you need 3–7 day delivery or address forwarding, Standard Class saves $0.20–$0.25 per piece on postage.
Use EDDM for saturation campaigns
EDDM's flat postage rate eliminates mailing list costs, addressing costs, and individual permit fees — the most efficient option when demographics don't matter.
Pre-sort your mail — always
Catdi Printing pre-sorts every campaign to earn the maximum USPS presort discount. This is included in our standard service.
Clean your list with NCOA before printing
Removing undeliverable addresses before printing means you don't waste printing and postage dollars on mail that won't deliver. NCOA processing pays for itself quickly.
Use a smaller mail piece size
Dropping from a 6×11 EDDM flat to a 6×9 postcard can save on both printing and in some cases postage weight thresholds. We'll help you find the best size for your budget.
