# Custom SMTP

> Send notification emails from your own email address

By default, notification emails are sent from the app's shared mail service, using your **Sender email** as the Reply-To address. If you'd rather send from your own domain or mailbox, configure **Custom SMTP** in **Email → SMTP Settings**.

<Note>
  Custom SMTP is available on the **Basic Plan** and above. See [Plans & Pricing](/billing/01-plans-and-pricing).

## Fields

| Field          | Example             | Notes                                                                              |
| -------------- | ------------------- | ---------------------------------------------------------------------------------- |
| Server address | `smtp.gmail.com`    | Your mail provider's SMTP host                                                     |
| Port           | `587`               | `587` for TLS, `465` for SSL                                                       |
| Email          | `example@gmail.com` | The mailbox you're authenticating as                                               |
| Password       | —                   | For providers like Gmail, use an **app password**, not your regular login password |
| Encryption     | `tls`               | Usually `tls` on port 587, or `ssl` on port 465                                    |

## Setting it up

<Steps>
  <Step title="Enter your SMTP details">
    Fill in server address, port, email, password, and encryption.
  </Step>

  <Step title="Verify">
    Click **Verify** to test the connection before saving. This confirms the app can authenticate with your mail server without sending anything yet.
  </Step>

  <Step title="Send a test email">
    Click **Send test email** to deliver a sample message and confirm end-to-end delivery.
  </Step>

  <Step title="Save">
    Once verified, click **Save**. From now on, all notification emails send through your SMTP server instead of the app's default mail, and your **Sender email** fields are replaced by your SMTP username.
  </Step>
</Steps>

<Warning>
  Always verify before saving — incorrect SMTP credentials will silently stop notification emails from sending until fixed.
