One of the most powerful capabilities for an AI agent is email access. Email connects to virtually every service, person, and business process. AgentMail provides the infrastructure to give your AI agent its own dedicated email inbox.
What AgentMail Does
AgentMail is an API that creates and manages email inboxes specifically for AI agents. Instead of connecting your personal Gmail or Outlook account (with all the security and permission concerns that brings), your agent gets its own dedicated inbox.
Key capabilities:
- Create inboxes on demand: Spin up new email addresses via API
- Send and receive: Full email functionality, not just reading
- Threads and replies: Maintains conversation context automatically
- Attachments: Handle files in both directions
- Custom domains: Use your own domain for professional appearance
- Structured data: Emails parsed into JSON for easy AI processing
Why This Matters for Automation
The Universal Protocol
Email connects to everything:
- Sign up for services
- Receive notifications and alerts
- Communicate with customers and vendors
- Get receipts and confirmations
- Trigger workflows from incoming messages
If your agent can handle email, it can interact with the entire digital world.
Asynchronous by Design
Unlike chat interfaces that expect immediate responses, email is naturally asynchronous. This matches how AI agents actually work - some tasks take time. Email lets your agent:
- Take complex requests that need research
- Respond when the work is done, not immediately
- Handle multiple conversations without real-time pressure
Built-in Identity
Every email address is an identity. Your agent becomes reachable at a specific address, can sign up for services, and maintains persistent relationships with contacts.
Practical Use Cases
Customer Support Triage
Set up an inbox like support@yourdomain.com. AgentMail receives messages, your AI agent categorizes them, drafts responses for common questions, and escalates complex issues to humans.
Service Monitoring
Create inboxes for different notification sources:
alerts@yourdomain.comfor system monitoringbilling@yourdomain.comfor invoice processingorders@yourdomain.comfor e-commerce automation
Your agent processes each type appropriately.
Automated Outreach
Send emails from your agent for:
- Follow-up sequences
- Appointment confirmations
- Report delivery
- Customer onboarding
Multi-Agent Coordination
Different agents can have different inboxes and communicate via email. This creates natural separation of concerns while maintaining a clear audit trail.
How It Works with OpenClaw
OpenClaw can connect to AgentMail to give your AI assistant email capabilities:
- Create an AgentMail account and get API credentials
- Configure the email skill in OpenClaw with your AgentMail API key
- Your agent can now send and receive email
The integration handles:
- Checking for new messages
- Parsing email content into a format the AI understands
- Sending responses with proper formatting
- Managing threads and conversations
Pricing
AgentMail offers a free tier to get started:
| Plan | Inboxes | Emails/Month | Storage |
|------|---------|--------------|---------|
| Free | 3 | 3,000 | 3 GB |
| Pro | 10 | 10,000 | 10 GB |
| Startup | 150 | 150,000 | 150 GB |
The free tier is enough for personal automation. Pro handles small business needs. Startup covers larger operations.
Deliverability
AgentMail handles the technical requirements for email deliverability:
- SPF, DKIM, DMARC: Authentication protocols configured automatically
- Reputation management: Shared infrastructure with maintained sender reputation
- Custom domains: Use your domain with proper DNS configuration
This matters because poorly configured email often lands in spam. AgentMail handles the complexity.
Privacy Considerations
Using AgentMail means your agent's emails pass through their infrastructure. Consider:
- Email content is processed on their servers
- API access gives them access to message content
- Evaluate their privacy policy for your use case
For highly sensitive communications, you might prefer self-hosted email infrastructure. For most automation use cases, AgentMail's approach is reasonable and significantly easier to set up.
Getting Started
- Sign up at agentmail.to
- Create your first inbox via the dashboard or API
- Connect to your AI agent using their SDK or MCP server
- Test by sending an email to your new inbox
The MCP server integration means you can add AgentMail to Claude Desktop, OpenClaw, or any MCP-compatible AI tool without writing code.
When AgentMail Makes Sense
Good fit:
- Automating email-based workflows
- Building customer support agents
- Processing notifications and alerts
- Multi-service integrations that rely on email
Consider alternatives when:
- You need complete control over email infrastructure
- Compliance requires on-premises email handling
- You're already managing email servers and want to extend them
Summary
Email is how the digital world communicates. AgentMail gives your AI agent a way to participate in that communication with dedicated inboxes, reliable deliverability, and APIs designed for automation.
For OpenClaw users building email automation, AgentMail is one of the simplest ways to add email capabilities without managing mail server infrastructure yourself.
