What QuantumDigital is
QuantumDigital is an online service for creating and sending direct-mail postcards. Customers can upload a design or use free templates, then provide their own mailing list or choose the company’s verified U.S. residential list. Campaigns can be scheduled weekly, monthly, or quarterly and targeted around listed properties or to customer contacts. QuantumDigital says postcards can enter the mail stream the next business day, and its APIs have next-business-day turnaround.
The Direct Mail API has a one-piece minimum and is listed at $0.85 per card, with postage, a mailing list, and in-house printing included. The Print / Ship API has a 20-piece minimum and costs $0.10 per card. EDDM postcard options start at 25,000 or more pieces: $35.00 USD, $40.00 USD, or $49 per piece, depending on format; postage is included. Features include variable-data personalization, Intelligent Mail barcodes, QR codes, SMS marketing, personalized landing pages, and coupon codes. APIs also support USPS navigation, consumer lists, uploaded designs or lists, and shipping small-order marketing materials. QuantumDigital serves real estate agents, local businesses, marketing agencies, and enterprise organizations.
