# Configure External SMTP Email Providers

<Callout icon="file-lines" color="#0EA5E9" iconType="regular">
  When updating your SMTP email provider’s host, port, or username, you need to provide your SMTP email provider password. To learn more, read [Deprecations and Migrations](/docs/troubleshoot/product-lifecycle/deprecations-and-migrations).
</Callout>

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. You can only configure one email provider which will be used for all emails.

Auth0 currently supports the following providers:

* [Mandrill](/docs/customize/email/smtp-email-providers/configure-mandrill-as-external-smtp-email-provider)
* [Amazon SES](/docs/customize/email/smtp-email-providers/configure-amazon-ses-as-external-smtp-email-provider)
* [Azure Communication Services](/docs/customize/email/smtp-email-providers/configure-azure-comm-service-as-smtp-email-provider)
* [Microsoft 365](/docs/customize/email/smtp-email-providers/configure-365-exchange-as-smtp-email-provider)
* [SendGrid](/docs/customize/email/smtp-email-providers/configure-sendgrid-as-external-smtp-email-provider)
* [SparkPost](/docs/customize/email/smtp-email-providers/configure-sparkpost-as-external-smtp-email-provider)
* [Mailgun](/docs/customize/email/smtp-email-providers/configure-mailgun-as-external-smtp-email-provider)

You can also configure a [third-party email provider](/docs/customize/email/smtp-email-providers/configure-custom-external-smtp-email-provider) such as Gmail or Yahoo.

You configure external email providers at [Auth0 Dashboard > Branding > Email Provider](https://manage.auth0.com/#/templates/provider).
