Adding multiple contacts (email addresses) to a flow

Hi there :)

I’m looking to see if there’s a way for a metric-based event flow to send to two different email addresses! I would love to avoid having to duplicate the flow and setting up a second metric to trigger off a different contact.

The use case is this: the metric-based event is triggered by someone signing up for a class. We need to be able to send an email to both the student who has signed up, and the parent/guardian of the student who has signed up.
