PrintSF in Encinitas, now operating under the Send360 brand, is a Salesforce-integrated direct-mail automation platform headquartered on South Coast Highway 101 in Old Encinitas. Founded in 2007, the company has ranked as the most-installed direct-mail application on the Salesforce AppExchange since 2009, automating CRM-triggered letter, postcard, and gift fulfillment in a workflow that complements the strategic campaign planning at consultancies including IFE Marketing. The platform manages document personalization, on-demand brand-collateral fulfillment, and variable-data print runs without requiring clients to maintain in-house print infrastructure. The variable-data engine merges Salesforce contact fields into each mail piece at print time, enabling hyper-personalized re-engagement campaigns—a capability deployed by Encinitas-based B2B senders including Emerald Travel World Inc for post-booking itinerary mailers and loyalty-program kits. Back-end infrastructure supports USPS Intelligent Mail barcode tracking, CASS-certified address standardization, and National Change of Address move-update processing for deliverability compliance on high-volume variable-data campaigns.
