What QuantumDigital is
QuantumDigital is a direct-mail service for designing, proofing, printing, and mailing postcards online. Customers can upload a finished design or choose from free postcard templates, then use their own mailing list or QuantumDigital’s verified U.S. national residential list. Campaigns can be scheduled weekly, monthly, or quarterly in advance and directed to mailing areas around listed properties or to the customer’s contacts. QuantumDigital says postcards can enter the mail stream the next business day; its APIs also have next-business-day turnaround.
The Direct Mail API supports USPS distribution, uploaded designs and lists, and orders starting at one piece. The Print / Ship API supports small marketing-material orders and has a 20-piece minimum. Other campaign options include Intelligent Mail barcodes, QR codes, SMS marketing, personalized landing pages, coupon codes, and variable-data personalization. Listed integrations include Salesforce, Top Producer, MoxiWorks, and others. The company identifies real estate agents, local businesses, agencies, and enterprise organizations among its customers. QuantumDigital was founded in 1986 and is headquartered in Austin, Texas. Its listed platforms are web and API.
