Robotomail

Give AI agents their own real email addresses with API-first email infrastructure built for autonomous workflows. Create mailboxes, send messages, receive replies, and manage conversations through a REST API using simple API-key authentication, without requiring a browser or SMTP server.

Designed for developers building agents with Claude, Gemini, LangChain, CrewAI, AutoGen, and similar frameworks, the platform makes email a programmable part of an agent workflow. Agents can access mail from CLI tools, curl, Python, or TypeScript, while a shareable /skill page helps make self-onboarding possible.

Key Features

Programmatic Mailbox Creation

Provision dedicated mailboxes directly through the API and assign each agent a real email address.

• Create mailboxes programmatically
• Give agents their own email identities
• Manage mailbox configuration through API calls
• Build email workflows without browser-based inboxes

Send and Receive Email Through an API

Agents can work with both sides of an email conversation through REST API endpoints.

• Send outbound messages with POST requests
• Receive inbound messages through webhooks
• Use SSE streaming for incoming mail
• Poll for new messages when needed
• Build fully automated email workflows

Automatic Email Threading

Keep related messages connected as conversations continue. Automatic reply handling helps agents maintain context across outbound messages and incoming responses.

This makes the infrastructure suitable for workflows where an agent needs to email someone, wait for a response, and continue working from the reply.

Custom Domains

Use email addresses on your own domain instead of relying only on platform-provided addresses.

• Configure DKIM
• Configure SPF
• Configure DMARC
• Maintain your own domain identity
• Support branded agent email addresses

Attachments

Agents can work with email attachments as part of their workflows.

• Send files with outbound messages
• Handle inbound attachments
• Access inbound files through download links
• Integrate document exchange into automated agent workflows

Webhook Security and Delivery

Inbound email events can be delivered to your systems with controls designed for reliable agent workflows.

• HMAC-signed inbound payloads
• Automatic webhook retries
• Webhook-based event handling
• SSE and polling alternatives for receiving messages

Mailbox Usage Controls

Set boundaries around how individual agent mailboxes can be used.

• Per-mailbox sending limits
• Storage quotas
• Suppression lists
• Control email volume and mailbox storage

Built For AI Agent Workflows

This infrastructure is designed around agents that need to operate email, rather than applications that simply need to send transactional messages.

It works with agent development environments and frameworks such as Claude, Gemini, LangChain, CrewAI, and AutoGen. Developers can also connect through familiar tools and languages including CLI, curl, Python, and TypeScript.

The API-first approach means an agent can create a mailbox, send an email, receive a reply, and continue a threaded workflow without opening a traditional email client.

Common Use Cases

Autonomous email agents: Give an AI agent its own address for communicating with customers, prospects, vendors, or other systems.

Agent-to-human workflows: Let agents initiate conversations, collect responses, and continue processing based on incoming replies.

Automated research workflows: Create mailboxes that can receive information, documents, or responses as part of an agent-driven process.

Customer and business operations: Build agents that handle email-based requests while keeping conversations organized into threads.

Developer-built agent systems: Connect email directly to Python, TypeScript, curl, CLI workflows, or frameworks such as LangChain, CrewAI, and AutoGen.

Pricing

Plans include a free tier alongside paid options. Paid plans include a 30-day money-back guarantee.

Why It Matters

Most email infrastructure is designed around either human inboxes or one-way transactional delivery. AI agents often need something different: a real address they can own, monitor, and use as part of an ongoing conversation.

With programmable mailboxes, inbound and outbound email, threading, webhooks, custom domains, attachments, and usage controls, this platform provides the infrastructure needed to make email a native capability of an AI agent.
