Can OpenClaw Send Email? What You Need to Know

Short answer: no, not out of the box. OpenClaw has no built-in email sending capability. It can draft text that looks like an email, but it cannot connect to an SMTP server, call an email API, or deliver a message to anyone’s inbox. With MCP tools, though, you can add full email sending to OpenClaw in a few minutes.

What OpenClaw Can Do Natively

OpenClaw is a local AI agent that communicates through messaging platforms like Telegram, Discord, and Signal. It handles conversational tasks well: answering questions, summarizing content, running through multi-step reasoning. If you ask it to “write an email to my boss about the project delay,” it will produce a perfectly good draft. The text will be there, formatted and ready.

It also supports MCP (Model Context Protocol), which means it can discover and call external tools at runtime. This is the mechanism that makes email possible, even though the core agent doesn’t include it.

What It Cannot Do Without Tools

The gap is delivery. OpenClaw cannot send that draft anywhere. It has no email client, no SMTP configuration, no integration with Gmail or Outlook or any mail service. The same applies to receiving email, checking inboxes, or replying to threads.

This limitation shows up in practical workflows more often than you’d expect. You might want OpenClaw to notify someone when a monitoring check finishes, send a daily summary to your team, or forward a piece of information to a colleague. Without an email tool, every one of those tasks ends with you copying text out of a chat window and pasting it into your mail client.

How MCP Tools Fill the Gap

AgentPatch provides a send-email tool that works through MCP. Once connected, OpenClaw can compose and deliver email in a single step. You give it the recipient, subject, and instructions for the body. The agent writes the message and sends it through AgentPatch’s email infrastructure. No SMTP credentials, no third-party mail accounts, no environment variables to manage.

The tool supports plain text and HTML email. OpenClaw can format messages with headers, bullet points, and links when the situation calls for it. You get a confirmation back in your chat when the message is delivered.

AgentPatch also offers a receive-email tool and a dedicated agent email address, so OpenClaw can handle two-way email communication if you need it.

Setup

The AgentPatch CLI is designed for AI agents to use via shell access. Install it, and your agent can discover and invoke any tool on the marketplace.

Install (zero dependencies, Python 3.10+):

pip install agentpatch

Set your API key:

export AGENTPATCH_API_KEY=your_api_key

Example commands your agent will use:

ap search "web search"
ap run google-search --input '{"query": "test"}'

Get your API key from the AgentPatch dashboard.

Install the AgentPatch skill from ClawHub — it teaches OpenClaw when to use AgentPatch and how to use the CLI:

clawhub install agentpatch

MCP Server (Alternative)

If you prefer raw MCP tool access instead of the skill, add AgentPatch to ~/.openclaw/openclaw.json:

{
  "mcp": {
    "servers": {
      "agentpatch": {
        "transport": "streamable-http",
        "url": "https://agentpatch.ai/mcp",
        "headers": {
          "Authorization": "Bearer YOUR_API_KEY"
        }
      }
    }
  }
}

Replace YOUR_API_KEY with your actual key from the AgentPatch dashboard. Restart OpenClaw and it discovers all AgentPatch tools automatically.

Example

You’ve been using OpenClaw to track something, maybe a price, a server metric, or a competitor’s product page. When the check is done, you want to share the results:

“Check the current price of the RTX 5090 on Amazon, then send a summary to [email protected] with the subject ‘GPU Price Update’.”

OpenClaw runs the web search, finds the current listing, composes a short email with the price and link, and sends it. You get the email in your inbox and a confirmation in Telegram.

Another common case is delegation:

“Send an email to [email protected]. Subject: Meeting reschedule. Let her know I need to move Thursday’s meeting to Friday at 2pm, and ask if that works.”

OpenClaw writes the message in a natural tone and sends it. The whole thing stays in your chat, no app switching required.

For recurring tasks, you can combine email with other tools:

“Search Google News for any articles about our company published today, then email me a digest at [email protected].”

OpenClaw runs the news search, pulls together the relevant results, and sends you a formatted summary. A workflow that would normally take ten minutes of browsing and writing collapses into one request.

Wrapping Up

OpenClaw cannot send email on its own, but MCP makes it straightforward to add. Once AgentPatch is connected, email becomes just another tool your agent can call, alongside web search, image generation, Google Maps, and the rest of the marketplace. Get your API key at agentpatch.ai.
