Direct Mail Printing Services in St. Louis, MO

Direct mail printing costs depend on quantity, size, paper stock, and mailing method. A standard 4x6 postcard mailing typically starts around a few cents per piece for printing, plus postage. EDDM postage is significantly cheaper than first-class mail. We provide detailed quotes that break out printing, mail prep, and postage costs separately — no hidden fees. Tell us your quantity and target area and we will have a quote to you within 4 hours.

The most popular sizes are 4x6, 6x9, and 6x11 inches. A 4x6 postcard qualifies for the lowest postage rates and works well for simple messages and coupons. A 6x9 gives you more design space while still mailing at postcard rates. A 6x11 oversized postcard stands out in the mailbox and is our most recommended size for maximum response rates. We print all sizes on premium card stocks from 14pt to 16pt with optional UV coating or soft-touch lamination.

Every Door Direct Mail (EDDM) lets you mail to every address on selected postal carrier routes without needing a mailing list. You choose the ZIP codes and routes you want to target, and USPS delivers to every residential or business address on those routes. EDDM postage rates are significantly lower than standard mail — currently around $0.21 per piece. MCI handles the entire process: printing, bundling by route, paperwork, and delivery to your local post office.

Variable data printing (VDP) allows each piece in a print run to be personalized with unique information — names, addresses, images, offers, or even entirely different designs. Instead of printing 10,000 identical postcards, you can print 10,000 unique postcards tailored to each recipient. Studies consistently show that personalized direct mail generates higher response rates than generic mailings. Our digital presses handle variable data at full production speed with no loss in quality.

Standard turnaround for most direct mail jobs is 5-7 business days from proof approval to USPS delivery. That includes printing, addressing, sorting, bundling, and delivery to the post office. USPS delivery time after that is typically 3-10 business days depending on mail class. For rush jobs, we can compress the print-and-prep timeline to 2-3 business days. Political campaigns and time-sensitive promotions get priority scheduling.

Yes. Direct mail consistently outperforms digital channels for response rates. The Data & Marketing Association reports average direct mail response rates of 2.7-4.4%, compared to 0.6% for email and 0.2% for digital ads. Mailboxes are less crowded than inboxes, and physical mail gets held, pinned to fridges, and shared with household members. Direct mail is especially effective for local businesses targeting specific neighborhoods — exactly what St. Louis businesses need.

Yes. We provide mailing list services including geographic targeting by ZIP code, carrier route, or radius around your business. We also offer demographic targeting by age, income, homeowner status, and other criteria.

You need a USPS bulk mailing permit to access presorted and bulk mail rates. If you do not have one, MCI can mail under our permit — we handle this routinely for clients. We take care of all postal paperwork, sorting, and compliance requirements. You just approve the proof and we handle everything from printing to post office delivery.
