# SMTP Toolkit

> Send email through any SMTP server using host, port, and optional login credentials

The **SMTP** toolkit lets agents send email through a standard SMTP server. Configure host and port (and optional username/password with TLS/SSL) as a saved connection.

Add it on the agent **Toolkits** tab and create or select an SMTP connection.

## Prerequisites

* SMTP host and port for your mail provider
* Optional: mailbox username and password (or app password) if the server requires auth
* An agent you can edit

## Setup

1. Open the agent → **Toolkits** → add **SMTP**.
2. Create a connection with **host** and **port** (required), plus **email** / **password** and TLS/SSL if needed.
3. Save the agent. `@`-mention the SMTP send tool when the agent should email someone.

## Available tools

| Tool           | Description                                        |
| -------------- | -------------------------------------------------- |
| **Send Email** | Sends an email through the configured SMTP server. |

## Use cases

* Send a summary or alert from chat to a stakeholder
* Notify a distribution list after a workflow completes

## Tips

* Prefer app passwords or SMTP credentials scoped to sending only.
* Store credentials in a saved connection — do not put them in the personality prompt.
* For Gmail or Outlook with OAuth toolkits, prefer those when available.

## Troubleshooting

| Symptom                      | What to check                                                                |
| ---------------------------- | ---------------------------------------------------------------------------- |
| Connection refused / timeout | Host, port, firewall, and TLS vs SSL settings                                |
| Auth failed                  | Username/password or app password; some providers require SMTP to be enabled |
| Message rejected             | From address allowed by the server; recipient address validity               |
