What it is
QuantumDigital lets customers design, proof, print, and send direct-mail postcards online. Users can upload a design or select free templates, then upload a mailing list or use the company’s verified U.S. national residential list. Campaigns can run weekly, monthly, or quarterly and target mailing areas around listed properties or customer contacts. QuantumDigital says postcards can enter the mail stream the next business day, with the same turnaround stated for API orders. The Direct Mail API accepts orders from one piece; Print / Ship API orders require 20 pieces. Tools include Intelligent Mail barcodes, QR codes, SMS marketing, personalized landing pages, coupon codes, and variable-data personalization. APIs support USPS navigation, consumer lists, uploaded designs or lists, and shipping small-order marketing materials. Direct Mail API pricing is $0.85 per card, while Print / Ship API pricing is $0.10 per card. EDDM formats are priced per piece and start at 25,000+ pieces.
