When creating an event registration page, you have the ability to customise every single one of the automated emails that get sent out when invitees register, confirm, cancel or get waitlisted.
When creating an event registration page, a small preview for each automated email is displayed in the E-mail Options section. To view the full email, click on the preview.
2. Once you open the email preview, you are able to read the subject and full copy. To customise the copy, simply edit it and save. Keep in mind that some emails such as the registration one, automatically add a link at the bottom of the email for confirming registration.
Also, the rich text editor lets you create rich content, including images.
