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 or Twilio instead.

How to automate emails

1

Connect to Resend

In the chat box, request your app to be integrated with Resend or click the plug icon  on the top right. Then, paste your Resend API Key
Resend only shows API keys once, immediately after you create it. If you didn’t save yours, create a new one.

Alternatively, you can click the plus icon + in the chat box to connect.

Enter your use case

Tell Zite how you want to use Resend in your app. In this example, we’ll send customers a booking confirmation every time they book an appointment.

If you haven’t verified your own domain in Resend, emails will be sent from onboarding@resend.dev by default and can only be delivered to your Resend account email.

Test

Be sure to test the app by performing the action required to trigger Resend. In this case, that would be booking an appointment.
