Sendoso is a corporate gifting and direct mail platform that lets sales, marketing, customer success and people teams send physical gifts, branded swag, eGifts, direct mail and charitable donations at scale. The Sendoso Core API (v3) automates sending against pre-configured campaigns — physical gifts to a known address, physical gifts with recipient address collection, and eGifts delivered by email or as embeddable links — while the Marketplace and SmartSend APIs send from an open catalog and let Sendoso pick the gift from the recipient's interests. A SCIM 2.0 surface handles user provisioning, an embeddable iFrame puts the whole send flow inside a partner application, and Svix-signed webhooks report twenty-eight send lifecycle events. Sendoso also ships an OAuth-protected MCP server, an agent skill and an A2A agent card, and integrates with Salesforce, HubSpot, Outreach, SalesLoft, Marketo and other CRM and sales engagement tools.
