# Send emails with Bolt.new and Resend

[Bolt.new](https://bolt.new) is a platform for building full-stack web and mobile apps via chat. You can add Resend in a Bolt.new project by asking the chat to add email sending with Resend.

## Guide

:::::steps
::::step{title="Add your Resend API key"}
To use Resend with Bolt.new, 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.

:::callout{intent="note"}
To safely store your Resend API key, use a `.env` file. You may need to
include this instruction in your prompt to bolt.new. Learn more about
[handling API keys](/guides/api-keys-knowledge-base-how-to-handle-api-keys).

:::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](/guides/get-started-add-a-domain).
2. Add the custom domain to the `from` field in the `resend` function in Bolt.new (or ask the chat to update these fields).

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