[Replit](https://replit.com/) is a platform for building sites and apps with AI. You can add Resend in a Replit project by asking the chat to add email sending with Resend.
**Example prompt**
```
When someone fills out the contact form, send an email using Resend.

## Guide
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](/dashboard/domains/introduction).
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`).
Replit tracks the details of your Resend integration in the [Integrations
page](https://replit.com/integrations).
