AgentMail is an inbox-as-an-API platform built for AI agents—provisioning, sending, replying, drafting, and inbound webhooks all available over a single HTTP API. The langchain-agentmail package wraps the AgentMail SDK as LangChain tools, plus a document loader and a retriever over an inbox.

​
Installation and setup

pip install langchain-agentmail
Get your API key from agentmail.to and set it as an environment variable: 
export AGENTMAIL_API_KEY="your-api-key"

​
Tools

See the AgentMail Toolkit guide for details on the available tools, including sending and replying to messages, managing drafts, attachments, and labels.

​
Document loader

See the AgentMail Document Loader guide for loading messages from an inbox as LangChain Documents—useful for indexing into a vector store for RAG over email.

​
Retriever

See the AgentMail Retriever guide for keyword search over an inbox.
