RE: Add dynamic event name url to a Thanks for attending Email
Hi, Chris
{{contact.contact_msevtmgt_event_msevtmgt_originatingeventid.msevtmgt_name}} is the answer which you need.
Here are the concrete steps.
1. Please make sure that the contact has registered the event already. The ‘Originating event’ will be filled automatically after registration.

2. Create an email template and add a textbox into it.

3. Add the event name with the assist edit function.

4. Set it into the customer journey and go live.

5. The contact who has registered the event will receive the email which contains the event name soon.

Hope this helps.
Best Regards,
Nya
