# Configure SendGrid as External SMTP Email Provider

Auth0 allows you to configure your own SMTP email provider so you can more completely manage, monitor, and troubleshoot your email communications. Auth0's built-in email infrastructure should be used for testing emails only.

## Prerequisites

* To ensure that emails can be sent from Auth0 to your SMTP, open ports and allow inbound connections from specific IP addresses. To update the list of IPs, navigate to [Dashboard > Branding > Email Provider](https://manage.auth0.com/#/branding/email_provider). See [Add IP Addresses to AllowList](/docs/secure/security-guidance/data-security/allowlist) for details.
* You must have a [SendGrid](https://sendgrid.com) account. If you have a Microsoft Azure subscription, you can get a free account in the Azure Marketplace.

## Configure SendGrid

1. Log in to your [SendGrid](https://sendgrid.com) account.
2. Navigate to SendGrid **Settings > API Keys**, and click **Create API Key**.
3. Type a name for your key and select **Restricted Access**.
4. Under **Access Details**, click to expand **Mail Send**.
5. Set the **Mail Send** permission to **Full Access**.
6. Click **Save** and copy the key value.
7. Navigate to Auth0 [Dashboard > Branding > Email Provider](https://manage.auth0.com/#/branding/email_provider).
8. Activate the **Use my own email provider** toggle.
9. Click the **SendGrid** logo.
10. Type a **From** email address, paste the SendGrid **API Key** you copied, and click **Save**.

**Note:** If you are using [passwordless authentication with email](/docs/authenticate/passwordless#email), ensure that the **From** email address value for your <Tooltip tip="Passwordless: Form of authentication that does not rely on a password as the first factor." cta="View Glossary" href="/docs/glossary?term=passwordless">passwordless</Tooltip> connection matches the **From** email address value you're using for SendGrid.

## Test email

You can now send a test email using the **Send Test Email** button. If you have configured everything correctly, you will receive a confirmation email. If you do not receive an email after a few minutes, please check your [Auth0 logs](https://manage.auth0.com/#/logs) for any failures.

The SendGrid [Email Activity](https://sendgrid.com/logs/index) page will now display delivery insights for all emails that have been sent to your users.
