Why people use Lob

Lob for Direct Mail and Postal Automation

With the Lob MCP, you just tell your AI agent what to do. You describe the recipient and the content, and the agent handles the verification, creation, and mailing. You get a confirmation and a tracking ID without ever leaving your chat window.
