# Sending Introduction

Mailofly provides a robust, scalable infrastructure for sending transactional emails and system notifications.

Whether sending verification codes, invoices, weekly digests, or alert notifications, Mailofly handles delivery with built-in DKIM signing, automatic rate limiting, and real-time delivery telemetry.

## Sending Methods

You can send emails using any of the following interfaces:

1. **REST API (`POST /api/emails`)**: Send emails over HTTP using cURL or your preferred HTTP client.
2. **Official SDKs**: Native, strongly-typed libraries for TypeScript/Node.js, Python, PHP, Go, and Dart.
3. **SMTP Gateway**: Connect any standard SMTP client or framework (Nodemailer, Laravel, PHPMailer, Supabase) via `smtp.mailofly.com:587`.
4. **AI MCP Server**: Enable AI coding assistants and autonomous agents to trigger sends with natural language.

## Anatomy of a Send Request

A basic send request requires:

* **`from`**: Sender address with your verified domain (e.g. `Acme <alerts@acme.com>`).
* **`to`**: One or more recipient email addresses.
* **`subject`**: Subject line of the email.
* **`html` or `text`**: Content of the email (or a `template_id`).

Optional features:

* **`attachments`**: Files or inline assets.
* **`scheduled_at`**: ISO-8601 timestamp for future delivery.
* **`headers`**: Custom headers (e.g. `In-Reply-To`, `List-Unsubscribe`).
* **`tags`**: Key-value pairs for filtering in analytics.
