Built for agents
Everything a working AI agent needs for email
Two-way email primitives
Send outbound email and receive inbound email through a single API. Inbound payloads include parsed body, headers, and pre-signed attachment URLs — ready for your agent to process without parsing.
Inbox aliases per agent
Each agent can have its own inbox alias and sending domain, with a scoped API key. Isolated reputation per agent — one agent's bounce behavior does not affect others.
Signed webhook events
13 event types delivered to your endpoint with HMAC-SHA256 signatures. Your agent can verify and act on delivery, open, click, bounce, complaint, and inbound events without polling.
Programmatic domain verification
Agents can provision new sending domains and verify them via API. SPF, DKIM, DMARC, and MAIL FROM records returned as structured data. No manual DNS copy-paste.
Framework-agnostic
Works with LangChain, CrewAI, AutoGen, Claude Agent SDK, and any agent framework that can make HTTP requests. TypeScript and Python SDKs map directly to tool-calling patterns.
MCP-compatible
Any MCP server that wraps HTTP can expose Bavimail email operations as tools. The REST API surface is stable across versions — no breaking changes between tool calls.

FAQ
Common questions about agent email
Can AI agents send and receive email through Bavimail?
Yes. Bavimail is designed for two-way programmatic email. Agents send via the REST API or SDK, and receive inbound email on a signed webhook — parsed headers, body, HTML, and attachment pre-signed URLs delivered directly to your endpoint.
Does Bavimail work with MCP (Model Context Protocol)?
Bavimail's REST API can be wrapped by any MCP server that handles HTTP endpoints. The TypeScript SDK maps cleanly to tool-calling patterns, and the webhook payloads are stable across API versions. Any MCP-compatible agent can send and receive email through standard HTTP calls.
Can each AI agent have its own dedicated email identity?
Yes. Bavimail supports per-agent inbox aliases and sending identities on a verified domain. Each agent can have a distinct email address, isolated sending reputation, and scoped API key. No inbox sharing between agents unless you explicitly configure it.
How does Bavimail handle email that an agent needs to act on?
Inbound email is delivered to your webhook endpoint as a structured JSON payload with parsed body, extracted headers, and pre-signed attachment download URLs. Your agent receives a signed event it can immediately act on — no IMAP polling, no mail parsing library required.
How does Bavimail compare to AgentMail for AI agent workflows?
Both platforms support programmatic send and receive for AI agents. Bavimail is significantly cheaper at most volume tiers and includes deeper operational tooling (suppression lists, deliverability dashboard, domain reputation). See the full comparison at /compare/agentmail.
