Lob

Lob is a direct-mail automation platform that lets businesses programmatically create, personalize, and send physical mail (letters, postcards, checks, and more) via developer-friendly APIs. Its nationwide print-and-mail network speeds delivery, optimizes postage and costs, and enforces compliance for regulated sends. Lob also provides address verification, integrations (SDKs, webhooks, CRM connectors), and analytics to automate workflows and scale targeted mail campaigns. Companies use Lob to connect digital systems to offline communications while maintaining control, tracking, and reporting across high-volume mail programs.
