    How EDDM Works in San Antonio

    1

    Target San Antonio Neighborhoods by Carrier Route

    Select routes in Alamo Heights, Stone Oak, Southtown, or the booming far West Side. We overlay USPS route demographics — household income, age, and household size — so you reach your ideal customer.

    2

    Design Pieces San Antonians Actually Keep

    Our designers build EDDM postcards with local flavor and a clear offer — pieces that survive the kitchen-counter sort instead of landing in the recycling bin.

    3

    Texas-Based Production

    Your EDDM postcards are produced at our Texas facility and shipped directly to San Antonio-area Post Offices. No cross-country delays, no handoffs to mystery vendors.

    4

    Post Office Preparation & Delivery

    We handle all USPS paperwork, bundling, and facing slips. Your prepared mailings are delivered to the appropriate Bexar County Post Offices for carrier route distribution.

    San Antonio EDDM Insider Tip

    San Antonio's growth is concentrated on the far North and West Sides — new subdivisions near Helotes, Alamo Ranch, and Schertz add carrier routes regularly, and new households haven't picked their go-to businesses yet. Check for new routes every quarter.

    To qualify for EDDM, a piece must be a USPS "flat" — longer than 10.5", taller than 6.125", or thicker than 0.25" (and within 15" × 12" × 0.75"). Standard 4" × 6" and 6" × 9" postcards do not qualify. Our team size-checks every piece against the USPS EDDM size rules before it prints.

    San Antonio EDDM Questions, Answered

    Postage is a flat $0.247 per piece anywhere in the San Antonio metro — the standard USPS EDDM Retail rate — plus printing, which varies by size, stock, and quantity. There's no mailing list to buy and no permit fee, and postage at Catdi is a 100% pass-through, itemized on your quote.
    Any active carrier route in Bexar County and the surrounding metro — Alamo Heights, Stone Oak, Southtown, the Medical Center area, and fast-growing suburbs like Alamo Ranch, Helotes, Converse, and Schertz. We map routes by household income, age, and household size before you commit.
    At our Texas production facility, then shipped directly to the San Antonio-area Post Offices serving your routes — bundled, faced, and with all USPS paperwork complete. Your campaign never leaves Texas.
    It's one of the best uses of the program. New subdivisions on the far North and West Sides add carrier routes as they build out, full of households actively choosing their dentist, mechanic, and favorite restaurant. Mailing those routes early builds loyalty before competitors show up in the mailbox.
