Using personalization tags within event variables - is it possible?
I have a metric-triggered flow in which the subject lines are dynamically populated via event variables. So the subject lines are set up as `{{event.subject_line}}`. When I post an event that has something like `subject_line: “Hey, {{first_name}}”` in the event payload, the subject line in the sent email looks exactly like that - it says “Hey, {{first_name}}”, without populating that name. Is there any way to make this work as desired (i.e. the first name set in the profile would actually be inserted)?
