# Custom confirmation emails
Send invitees your own custom confirmation email — with your own subject, body, formatting, and event variables — immediately after they book.
### Common use cases
* Include preparation instructions — what to bring, how to prepare, where to park, how to join.
* Link to your intake form so the invitee can fill it out before the meeting.
### How it works
Custom confirmation emails are available on the Pro plan and above. When enabled, your custom email is sent to the invitee (and any guests) immediately after the event is scheduled.
What it sends alongside depends on whether you have a calendar connected:
* **Calendar connected (Google or Outlook):** The calendar service sends its own event invitation. Your custom email is sent **in addition** — alongside the calendar invite.
* **No calendar connected:** zcal would normally send its own default booking confirmation. Your custom email **replaces** that default.
Reminders, reschedule notifications, and cancellation notifications continue to use zcal's default content regardless of calendar setup.
#### Enable a custom confirmation email
1\) Edit your invite link. Under `Scheduling Options` turn on the `Custom confirmation email` switch.
### Customize the confirmation email
1\) Click the Edit button next to the `Custom confirmation email` switch.
2\) Edit the subject and body of the email. You can format your email and add links.
3\) You can also insert event variables into the email — for example, the invitee's name, the event date and time, or the reschedule and cancel links.
4\) Click Save.
