How Bulk Mail Saves You Money
Postage is typically the largest expense in any direct mail campaign — often more than the printing itself. USPS offers significant discounts to mailers who presort their mail by ZIP code, carrier route, and delivery point. The catch? You need the equipment, software, and postal expertise to do it right.
That's where MCI comes in. Our mailing department processes millions of pieces annually from our St. Louis facility. We run your list through NCOA address verification, CASS certification, and deduplication — then presort every piece to qualify for the deepest available discounts. The result: 30-50% savings compared to First Class postage.
For a 10,000-piece mailing, that's $1,500-3,000 in postage savings. For organizations mailing monthly or quarterly, the annual savings add up fast. And because we print and mail under one roof, there's no shipping cost to get your printed pieces to a separate mail house.

Bulk Mail FAQs
How much can I save with bulk mail in St. Louis?
Typical savings range from 30-50% compared to First Class postage rates. The exact discount depends on your list size, mail piece specs, and how well your addresses presort. A 10,000-piece mailing can save $1,500-3,000 in postage alone. We provide exact postage quotes before production so there are no surprises.
What is the minimum quantity for bulk mail rates?
USPS Marketing Mail (bulk rate) requires at least 200 pieces for postcards or 500 pieces for letters. However, presort savings improve significantly with larger quantities. Lists under 2,500 pieces may see limited discounts because you need enough pieces to fill carrier route trays and bundles for the deepest rates.
What is NCOA processing and why does it matter?
NCOA (National Change of Address) checks your mailing list against USPS records of people who have moved in the past 48 months. Addresses are updated automatically, which improves deliverability and reduces waste. NCOA processing is required by USPS to qualify for bulk mail automation rates — it's not optional if you want the best postage discounts.
How long does bulk mail delivery take?
USPS Marketing Mail typically delivers in 3-10 business days, with most pieces arriving in 5-7 days. Delivery timing is less predictable than First Class. For time-sensitive campaigns, we coordinate multi-point postal entry to tighten delivery windows. We can also split large mailings into waves for staggered delivery.
Do I need my own mailing permit for bulk mail?
You need a USPS bulk mail permit to access presorted rates. If you do not have one, MCI mails under our permit at no extra charge. We handle all postal paperwork, permit imprints, and USPS compliance. Many of our clients have mailed with us for years without ever needing their own permit.
Can you print and mail in one step?
Yes. MCI is a full-service print and mail shop. We print your mail pieces on our in-house presses, then walk them across the production floor for addressing, sorting, and postal preparation. Your job never leaves our building until it is on a mail truck. One vendor, one invoice, no coordination headaches.
