# Send emails using Supabase with SMTP

> Learn how to integrate Supabase Auth with Resend SMTP.

## Prerequisites

Before you start, you'll need:

* A Resend [API key](/docs/create-an-api-key)
* A [verified domain](/docs/add-a-domain)

## Guide

**1. Get the Resend SMTP credentials**

When configuring your SMTP integration, you'll need to use the following credentials:

* **Host**: `smtp.resend.com`
* **Port**: `465`
* **Username**: `resend`
* **Password**: `YOUR_API_KEY`

**2. Integrate with Supabase SMTP**

After logging into your Supabase account, you'll need to enable the SMTP integration.

1. Go to your Supabase project
2. Click on **Authentication** in the left sidebar
3. Click **Email** under the **Notifications** section
4. Click **SMTP Settings**
5. Add your Sender email and name (these are required fields). For example: `support@example.com` and `ACME Support`.
