Harte Hanks is a marketing and customer experience outsourcing company that provides B2B and B2C brands with end-to-end services spanning marketing, customer care, and fulfillment and logistics. Clients use Harte Hanks as an outsourced partner to handle functions they prefer not to run in-house, including demand generation, customer support, and product distribution. Harte Hanks serves large multinationals, small and medium-sized businesses, and government organizations across B2B technology, healthcare, consumer products, financial services, and retail. The company operates through three units: marketing and demand generation (data analytics, creative, digital advertising, and fully outsourced marketing operations); customer care (outsourced customer service via human agents augmented by AI and CRM tools); and fulfillment and logistics (physical order fulfillment and 3PL services through FDA-registered fulfillment centers and a contracted fleet of over 15,000 trucks). Harte Hanks earns revenue primarily through one-to-three year service contracts, though most lack minimum spend commitments and are terminable on short notice. Revenue drivers vary by unit — marketing revenue scales with program scope, customer care with interaction volume and agents deployed, and fulfillment with order volume and warehousing needs. Harte Hanks argues its differentiator is integrating across the full customer lifecycle rather than offering point solutions, and it tries to enter accounts through one service line before expanding into others. The top 25 clients account for roughly 68% of revenue, with the largest single client at about 10.5%.
