## Guide

:::::steps
:::step{title="Add a custom domain to your Resend account"}
By default, you can only send emails to your own email address.

To send emails to other email addresses:

1. Add a [custom domain to your Resend account](https://resend.com/domains).
2. Add the custom domain to the `from` field in the `resend` function in Replit (or ask the chat to update these fields).

Get more help adding a custom domain in [Resend's documentation](/guides/learn-dashboard-domains-introduction).
:::

::::step{title="Add your Resend API key and from address"}
To use Resend with Replit, you'll need to add a Resend API key, which you can create in the [Resend Dashboard](https://resend.com/api-keys). Do not share your API key with others or expose it in the browser or other client-side code.

The from address is the email address that will be used to send emails. Use your custom domain you added in step 1 here (e.g., `hello@example.com`).
