AgentMail

AgentMail is a community skill for AI agent email management, covering inbox creation, message sending and receiving, email parsing, attachment handling, and programmatic email operations designed specifically for AI agent workflows.

What Is This?

Overview

AgentMail provides API-first email infrastructure designed specifically for AI agents to send and receive emails programmatically. It covers inbox creation that generates dedicated email addresses for each agent or workflow with custom domain support and automatic routing, message sending that delivers emails with HTML formatting, attachments, and custom headers through simple API calls, message receiving that retrieves incoming emails with full content including body text, sender information, and metadata, email parsing that extracts structured data from email content including subjects, recipients, and message threads, and attachment handling that uploads and downloads files associated with emails automatically. The skill enables AI agents to participate in email-based workflows and communication channels without complex SMTP and IMAP configuration.

Who Should Use This

This skill serves AI agent developers needing email capabilities, automation builders creating email-triggered workflows, and teams integrating agents into customer communication channels.

Why Use It?

Problems It Solves

Traditional email infrastructure requires complex SMTP and IMAP server configuration that is difficult to automate. AI agents need temporary or dedicated email addresses for testing and production workflows without manual account setup. Parsing incoming emails to extract relevant information requires handling various email formats and encodings. Managing email authentication, spam filtering, and deliverability is challenging without dedicated email infrastructure and expertise.

Core Highlights

Inbox generator creates dedicated email addresses with custom domains and routing rules. Message sender delivers emails with attachments and formatting through simple API calls. Message receiver retrieves incoming emails with full content and metadata. Parser extracts structured data from email content and threads.

How to Use It?

Basic Usage

import requests
import os

api_key = os.environ['AGENTMAIL_API_KEY']
headers = {
    'Authorization': f'Bearer {api_key}'
}

inbox = requests.post(
    'https://api.agentmail.com/inboxes',
    json={'name': 'support-agent'},
    headers=headers
).json()

inbox_email = inbox['email']

message = requests.post(
    'https://api.agentmail.com/messages',
    json={
        'from': inbox_email,
        'to': 'customer@example.com',
        'subject': 'Order Confirmation',
        'body': 'Your order has been shipped.'
    },
    headers=headers
)

Real-World Examples

messages = requests.get(
    f'https://api.agentmail.com'
    f'/inboxes/{inbox["id"]}/messages',
    headers=headers,
    params={'since': '2025-03-01T00:00:00Z'}
).json()

for msg in messages['data']:
    print(f'From: {msg["from"]}')
    print(f'Subject: {msg["subject"]}')
    print(f'Body: {msg["body"]}')

with open('report.pdf', 'rb') as f:
    attachment = requests.post(
        'https://api.agentmail.com/attachments',
        files={'file': f},
        headers=headers
    ).json()

message_with_attachment = requests.post(
    'https://api.agentmail.com/messages',
    json={
        'from': inbox_email,
        'to': 'recipient@example.com',
        'subject': 'Monthly Report',
        'body': 'Please find attached.',
        'attachments': [attachment['id']]
    },
    headers=headers
)

Advanced Tips

Use webhook endpoints to receive real-time notifications when emails arrive instead of polling the inbox repeatedly for new messages. Implement email threading logic to group related messages together by parsing In-Reply-To and References headers for conversation context. Configure custom routing rules to forward specific emails to different inboxes or trigger automated workflows based on sender or content patterns.

When to Use It?

Use Cases

Build a customer support agent that monitors a shared inbox and automatically responds to common inquiries with relevant information. Create an email-based notification system where agents send status updates and alerts to users through dedicated email addresses. Implement email verification workflows where agents send confirmation emails and process user responses programmatically.

Important Notes

Requirements

AgentMail API key configured for authentication and access to email sending and receiving capabilities. Understanding of email standards including MIME types, headers, and threading for effective email handling and parsing. Webhook endpoint configured if implementing real-time email notifications instead of polling for new messages periodically.

Usage Recommendations

Do: implement proper email validation and spam filtering before processing incoming messages to avoid malicious content. Use dedicated inboxes for different agents or workflows to maintain clear separation and easier debugging. Monitor email deliverability metrics and bounce rates to ensure messages reach recipients successfully without ending up in spam.

Don't: send unsolicited emails or spam since this violates anti-spam regulations and will result in account suspension. Store sensitive information in email content without encryption since email is inherently insecure without additional protection. Ignore bounce notifications and delivery failures since they indicate problems requiring attention.

Limitations

Email delivery is not instantaneous and can experience delays based on recipient server configurations and network conditions. Some email providers may filter or block messages from new domains until sender reputation is established over time. Large attachments may be rejected by recipient servers with size limits requiring alternative file sharing approaches. API rate limits apply to inbox creation and message sending operations depending on subscription tier and usage volume.
