Details

SMTP Mailer is a streamlined email sending service designed for AI agents and automation workflows to deliver messages through any standard SMTP server. It accepts connection credentials via an intuitive URL format supporting both plain SMTP and encrypted SMTPS connections, making configuration straightforward without complex parameter handling. Recipients can be specified as a single address, an array, or a comma-separated string, with support for CC and BCC fields for flexible distribution. The tool sends both plain text and HTML formatted emails, enabling rich content delivery including formatted newsletters, styled notifications, and branded communications. File attachments are supported through base64-encoded content with configurable MIME types for documents, images, and other media. Email priority levels allow marking messages as low, normal, or high importance for recipient mail client handling. The sender address can be explicitly set or automatically derived from the SMTP username, simplifying configuration for common use cases. This tool is optimized specifically for email delivery. For workflows requiring additional protocols such as FTP file transfers, SSH command execution, or MQTT messaging alongside email, use the Protocol Bridge tool which provides a unified interface across multiple network protocols.

Autonomous agents can access this tool through AgentAddress credit balances or direct x402 payments. Use the Autonomous Agent API reference for endpoint shapes after choosing the access pattern below.

Recommended

Credit-Based Access Using AgentAddress

AgentAddress is preferred when an autonomous agent needs persistent file access, stored platform state, or maximum tool use ability across repeated calls.

Open Credit-Based Access Using AgentAddress

Direct x402 Payment

Use direct x402 for independent one-off tool calls that do not require shared files or stored platform state.

Accepted public payments

Stablecoin: USDC
Chains: Base, Arbitrum, Optimism, Polygon, and Avalanche

Direct x402 payments are not enabled for this product; use AgentAddress credit access instead.

Product Skill Package

This product has a published Agent Skill package. Install it when an autonomous agent needs product-specific operating instructions in its local skill registry.

  "to": ["recipient@example.com"],
  "subject": "Monthly Status Update",
  "body": "Hello,\n\nHere is the monthly status update.\n\nBest regards,\nThe Team"

  "subject": "Welcome!",

Common Workflows

Send a notification email — Use the send action with plain text body to deliver a quick notification to one or more recipients.
Send a formatted newsletter — Set body_type to "html" and provide styled HTML content with images and links.
Distribute a report with attachments — Attach base64-encoded files (PDF, CSV, Excel) and send to recipients with CC for visibility.
Confidential distribution — Use bcc to send to multiple recipients without revealing other addresses.
Urgent communication — Set priority to "high" to flag the email as important in recipient email clients.

Important Notes

Gmail users: You must use an App Password, not your regular account password. Generate one at https://myaccount.google.com/apppasswords.
SMTP URL schemes: Use smtp:// for STARTTLS (port 587, recommended) or smtps:// for direct SSL/TLS (port 465).
Attachment size limit: Total attachment size must not exceed 25MB.
From address: Some providers (like Gmail) enforce that the sender address matches the authenticated account. Use from_email only when your provider allows sending from an alias.
Priority: Use "high" priority sparingly to avoid emails being flagged as spam.
Common MIME types for attachments: application/pdf, text/csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet (Excel), image/png, image/jpeg, text/plain.

How does an external agent use this tool?

After the external agent is connected to an Agent Group that can use this tool, paste this prompt into the agent:

Agent prompt

Use the AgentPMT-Tool-Search-and-Execution tool. First call action 'get_instructions' so you know how to use the tool search interface. Then call action 'get_schema' with tool_id 68bf8f07b0ef2f262f41dace ("SMTP Email Delivery Service"). After reading the schema and any returned instructions, tell me what this tool can do, we are going to be using it

The agent should fetch the tool schema first, collect the required parameters for your request, and then call the tool through AgentPMT.
