# Configure Resend as an Email Provider

> Instructions on how to configure Resend as an email provider with Auth0.

## Prerequisites

* You must have a [Resend](https://resend.com) account.

* You must verify at least one domain with Resend before you can send emails. To learn more, read Resend's [domain verification documentation](https://resend.com/docs/dashboard/domains/introduction).

* You must configure your provider to allow inbound connections from specific [Auth0 IP addresses](/docs/secure/security-guidance/data-security/allowlist).

## Configure Resend

1. Log in to your [Resend](https://resend.com) account.
2. Navigate to **API Keys** and click **Create API Key**.
3. Type a name for your key, select the appropriate permission level and domain, and click **Add**.

4. Copy the API key value. You will not be able to see it again.
5. Navigate to Auth0 [Dashboard > Branding > Email Provider](https://manage.auth0.com/#/branding/email_provider).
6. Activate the **Use my own email provider** toggle.
7. Select the **Resend** logo.
8. Type a **From** email address, paste the Resend **API Key** you copied, and click **Save**.

The **From** email address must use a domain you have verified with Resend. If you are using [passwordless authentication with email](/docs/authenticate/passwordless#email), 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 must match the **From** email address value you're using for Resend.

## Send a test email

Send a test email using the **Send Test Email** button. If the configuration is correct, you will receive a confirmation email. If you do not receive an email after a few minutes, check your [Auth0 logs](https://manage.auth0.com/#/logs) for error codes.

Once configured, the Resend [Emails](https://resend.com/emails) page displays delivery insights for all emails that have been sent to your users.
