# Mail (SMTP)

> Send emails over SMTP.

Lets an agent send emails through FlyMyAI's managed SMTP relay.

## What it can do

| Method | What it does |
| --- | --- |
| `mail_send` | Send an email. Supports plain text, HTML, CC, BCC, and Reply-To. |

## Setup

Nothing to configure. Mail is a managed FlyMyAI SMTP relay - the sending
server and credentials are handled for you on the FlyMyAI side. There are
no SMTP host, username, or password fields to fill in, and no app password
or API key to create. Just add the tool to your agent and start sending.

## Troubleshooting

- **Messages land in spam** - keep the body and subject clear and avoid
  spam-trigger phrasing; recipients can also allowlist the sender so
  future messages land in the inbox.
- **Send failed** - retry the request; transient relay errors usually
  resolve on a second attempt.
