Why choose Dimaco for direct mail: everything in-house, one point of contact
Most printers outsource their mailing to a third-party lettershop. We don't. Every step of your campaign — list processing, design, printing, inkjet addressing, presort, and USPS induction — happens at our Carrollton, TX facility. That means fewer handoffs, fewer errors, faster turnarounds, and a single point of accountability when you have a question or a deadline.
We've been running direct mail campaigns for over 40 years. That experience means we know which formats drive the highest response rates for your industry, which postage class makes sense at your volume, how to time your drops for maximum in-home impact, and where most campaigns lose money to bad data. We bring that knowledge to every client — not just the big ones.

Direct mail capabilities: everything your campaign needs
From raw data to in-home delivery — we manage the entire workflow.
Targeted Mailing List Sourcing
We source consumer and B2B mailing lists filtered by ZIP code, carrier route, income bracket, age range, homeownership status, presence of children, business type, and hundreds of other selects. You only pay to reach the people most likely to respond.
NCOA Data Processing & CASS Certification
We run your existing list through the USPS National Change of Address database and CASS address standardization — ensuring every piece is deliverable, reducing returns, and qualifying your mail for automation postage discounts.
Direct Mail Design & Copywriting
Our in-house design team creates postcards, letter packages, self-mailers, and oversized flats that are visually compelling and USPS-compliant. We optimize for response: clear headline, strong offer, and a single call to action.
Printing, Variable Data & Inkjet Addressing
High-speed digital and offset printing with variable data capabilities means every piece can carry the recipient's name, a unique offer, or a personalized QR code. Inkjet addressing is done in-house on our mailing equipment — not outsourced.
USPS Presort & Postage Optimization
We presort your mail by ZIP code, carrier route, and USPS automation standards to earn the lowest possible postage rates. At high volumes, presort discounts can reduce your postage cost by 30–35% versus single-piece First-Class rates.
USPS Induction & Intelligent Mail Tracking
We induct your mail directly with the USPS, bypassing retail rates entirely. Every campaign includes Intelligent Mail Barcode tracking so you can see delivery progress by geography and time — and plan your sales follow-up accordingly.

The Full Direct Mail Process — From Data to Delivery Tracking
A successful direct mail campaign is not a single task — it is a sequence of interdependent steps, and a breakdown at any one of them can quietly erode your response rate. At Dimaco, the entire workflow runs through our Carrollton facility, which means each handoff is internal and accountable. The process begins with data: we pull or clean your mailing list, run NCOA and CASS certification to update addresses and verify deliverability, and apply any suppression files you need. A clean list is the single highest-leverage investment you can make before a single piece goes to press.
Next is design. Our in-house team builds the piece — postcard, letter, self-mailer, or flat — around your offer, brand standards, and USPS specifications. We design for response: a clear headline, a compelling offer, and one call to action. Once art is approved, production moves to press. We print on digital and offset equipment with variable data capability, meaning every piece can carry a recipient-specific name, offer, or QR code. After printing, inkjet addressing and any personalization are applied in-house on our mailing equipment — not sent to a third-party lettershop.
The final stages are presort, induction, and tracking. We sort your mail by ZIP code and carrier route to earn USPS automation postage discounts of up to 30–35% versus single-piece rates, then induct directly with the USPS — bypassing retail rates entirely. Every campaign includes an Intelligent Mail Barcode so you can monitor delivery progress by geography and date. Knowing when your mail lands in-home lets you time sales follow-up calls and digital retargeting to coincide with peak response windows, which is where most of the ROI from direct mail is actually captured.
Direct Mail Formats and Specs — Postcards, Letters, and Self-Mailers
The format you choose drives both cost and response, and the right choice depends on your audience, offer, and budget. Postcards are the workhorse of direct mail: they are inexpensive to print, have no envelope to open, and deliver your message the instant the piece is pulled from the mailbox. Standard postcard sizes include 4.25 × 6, 6 × 9, 6 × 11, and oversized 9 × 12. Larger postcards command more attention and higher response rates but cost more in paper and postage. For saturation and EDDM campaigns, oversized formats (9 × 12 and up) consistently outperform smaller pieces on recall and response.
Letter packages — an envelope plus a letter, reply card, and optional insert — are the format of choice for fundraising, insurance, financial services, and any campaign where a longer message builds the case for a considered purchase. Letters feel personal and private, which is why they outperform postcards for high-trust, high-value offers. Self-mailers (folded pieces that mail without an envelope, such as bi-folds and tri-folds) sit between postcards and letters in both cost and response — they offer more real estate than a postcard while remaining envelope-free. Stock weight and finish affect perception: a heavier 14pt or 16pt cover stock with a soft-touch or UV coating signals quality and durability, which matters for brand-conscious campaigns.
USPS dimensional requirements govern postage qualification. To earn automation rates, a postcard must be between 3.5 × 5 and 6.125 × 11.5 inches; letter-size pieces must fall within 3.5 × 5 and 6.125 × 11.5 inches and no more than 0.25 inches thick; flats exceed those maximums and mail at flat rates. Bleed, trim, and safe-zone margins must be set correctly in artwork to avoid white borders or cut-off text. Dimaco's prepress team reviews every file against USPS specs before it goes to press, catching issues that would otherwise trigger postal rejections or costly reprints.
Postage Classes — First-Class Mail vs USPS Marketing Mail
Choosing the right postage class is one of the easiest ways to reduce campaign cost without sacrificing results — and the decision should be driven by content, urgency, and volume. First-Class Mail is required for any piece that contains personal information (bills, statements, account updates) or is time-sensitive. It delivers in 1–3 business days, includes return service and forwarding at no extra charge, and is the only option for mail that must feel personal. For appointment reminders, renewal notices, and account-driven communications, First-Class is non-negotiable.
USPS Marketing Mail (formerly Standard Mail) is the economical choice for advertising and promotional mail — postcards, flyers, catalogs, and promotional letters that are not time-sensitive. Marketing Mail delivers in 3–10 business days (the wider window reflects its lower priority in the USPS network) but costs significantly less per piece, especially after presort discounts. For a 10,000-piece postcard campaign, the difference between single-piece First-Class and presorted Marketing Mail can amount to thousands of dollars in postage. The tradeoff is delivery speed: if your offer has a hard deadline, build extra lead time into your schedule or upgrade to First-Class.
Nonprofit organizations that have been approved for USPS Nonprofit Marketing Mail rates receive an additional discount of roughly 40% below standard Marketing Mail rates — a meaningful savings for donor appeals and community outreach. Dimaco handles nonprofit authorization paperwork and ensures your pieces carry the correct indicia. We also run presort on every campaign, which is the mechanism that unlocks automation discounts for both First-Class and Marketing Mail. Our team will recommend the postage class that balances your delivery timeline against your budget, and we quote postage line-by-line so there are no surprises after the job drops.
