Lets say, used an event trigger as an action to send an email.

In that email I only have the merge tags of the user (so I am doomed to store everything on the user).

I'd like to use the event properties from the event (action trigger) of the flow in the email template.

E.g.
I have an PostCreatedEvent that has properties on it. I have a post notification email.
I wanna use the "title" property of the PostCreatedEvent in the email that is the post notification email
