# Send emails with Resend

> Send transactional emails from your own domain when key actions occur in your Zite app.

## How it works

Send emails from your own domain when app actions, such as submitting user info, completing a booking, or placing an order, happen in your Zite app. By connecting Zite to Resend, you can:

* Send emails from your own branded name and domain (requires access to your domain’s DNS settings)
* Automate booking confirmations, receipts, invoices, and other transactional emails
* Send emails with attachments such as PDFs, documents, and images
* Schedule emails for specific dates and times, such as appointment reminders

Looking to send newsletters and marketing emails? We recommend using [Mailchimp](https://www.zite.com/help/integrations/mailchimp) or [Twilio](https://www.zite.com/help/integrations/twilio) instead.

## How to automate emails

<Steps>
  <Step title="Connect to Resend">
    In the chat box, request your app to be integrated with Resend or click the `plug icon` <Icon icon="plug" /> on the top right. Then, paste your [Resend API Key](https://resend.com/api-keys). 

    <Note>
      Resend only shows API keys once, immediately after you create it. If you didn't save yours, create a new one.
    </Note>

    <Note>
      If you haven't verified your own domain in Resend, emails will be sent from [onboarding@resend.dev](mailto:onboarding@resend.dev) by default and can only be delivered to your Resend account email.
    </Note>
  </Step>

  <Step title="Test">
    Be sure to test the app by performing the action required to trigger Resend. In this case, that would be booking an appointment.
