# Metabase (SMTP)

> Send Metabase dashboard subscriptions and alerts through MailBlastr over SMTP.

Metabase emails dashboard subscriptions, alerts, and account notifications over SMTP. Configure it with the MailBlastr relay and authenticate with your API key so those emails are delivered and tracked in your dashboard.

## Prerequisites

- A MailBlastr [API key](https://www.mailblastr.com/docs/api-keys/overview).
- A [verified domain](https://www.mailblastr.com/docs/domains/managing) to send from.

## 1. Get your SMTP credentials

You'll configure Metabase with the following MailBlastr credentials:

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `Host` | string | No | `smtp.mailblastr.com` |
| `Port` | number | No | `465` (implicit TLS) or `587` (STARTTLS). |
| `Username` | string | No | `mailblastr` |
| `Password` | string | No | Your API key, e.g. `mb_xxxxxxxxx`. |

## 2. Configure SMTP in Metabase

After logging into Metabase, enable the SMTP integration:

1. **Open email settings** — From the Admin Panel, go to **Settings > Email** in the left menu.
2. **Enter credentials** — Enter the MailBlastr host, port, security (SSL for `465`, STARTTLS for `587`), username (`mailblastr`), and password (your API key) from the section above. Set the **From Address** to an address on your verified domain.
3. **Save** — Click **Save**. All Metabase emails are now sent through MailBlastr.

> **Warning:** The **From Address** must be on a domain you have verified in MailBlastr, otherwise sends will be rejected.
