Yes. For any event that is generating tickets each registrant receives an email after submitting their transaction which contains a PDF attachment of their event tickets. While setting up your event you can now edit the subject line and body text of that specific email.

Within the setup of your Event go to the Event Settings tab and scroll down to the “Ticketing” section. With the “Ticket Event” setting toggled to YES you will also find the “Customize Ticket Email Message” setting. Turning this setting to YES will reveal two new text boxes. The first text box will allow you to customize the subject line of the email under Ticket Email Message Title. The second larger text box will allow you to customer the body text. Along with the text you can also insert Mail Merge fields related to the event transaction as well as edit the format and styling of your text.
