Sendoso MCP can now send campaigns and Party Links from AI assistants

In its October 2026 product updates, Sendoso extended its MCP server so connected AI assistants can act on campaigns and Party Links that humans set up in Sendoso. The company describes the model as humans setting up the campaign and agents using it at the right moment, subject to existing limits and approvals. The month's updates also add a Marketo integration for program tracking, a rebuilt bundle creation flow, cleaner bundle previews for recipients, and marketplace and inventory management changes.

The details

• The October entry lists Sendoso MCP on Starter, Core, Advanced and Enterprise plans, with each user connecting their own Sendoso seat.
• Campaign sending through MCP is listed for accounts on Core, Advanced or Enterprise plans with access to campaigns.
• Marketo Program Tracking lets users choose a channel and program and map Sendoso statuses to Marketo statuses.
• New Bundle Creation is available on all Sendoso plans.
• SmartSend limit options of $150 and $250 were added.

Context

Sendoso opened a request-based beta of its MCP server on June 24, 2026 and made Sendoso MCP available as an action in Databricks Genie and AI Playground in September 2026. Existing coverage of October 2026 covers the redesigned send flow and handwritten note campaigns. Sendoso introduced its Oso AI agent in March 2026 and made Oso sending generally available to senders in May 2026.
