# Sending Supabase Auth Emails with Mailofly

By default, Supabase enforces strict rate limits on authentication emails (password resets, magic links, confirmations). You can remove these limits and brand your delivery domain by configuring Mailofly custom SMTP in Supabase.

***

## Supabase Dashboard Setup

1. Open your **Supabase Dashboard** → select your project.
2. Navigate to **Project Settings** → **Authentication**.
3. Scroll down to the **SMTP Settings** section and toggle **Enable Custom SMTP**.
4. Fill in the following credentials:

| Field                         | Value                                                               |
| :---------------------------- | :------------------------------------------------------------------ |
| **Sender Email**              | An address using your verified domain (e.g. `auth@yourcompany.com`) |
| **Sender Name**               | Your app or company name                                            |
| **Host**                      | `smtp.mailofly.com`                                                 |
| **Port Number**               | `587`                                                               |
| **Minimum Transfer Security** | `STARTTLS`                                                          |
| **Username**                  | `mailofly`                                                          |
| **Password**                  | Your secret Mailofly API Key (`mfly_live_...`)                      |

5. Click **Save Changes**.
6. Send a test confirmation email to verify connection. All Supabase Auth emails will now be signed with your domain's DKIM and tracked in your Mailofly dashboard.
