Hi Christoph -
Sorry about the clarity - HubSpot mentioned this could be added as a custom code somehow in our account. They just couldn’t show us how.
The idea would be for this code (‘My Schedule’ text linked to ‘{{contact.hubspot_owner_id.meetings_link}}’) to be available as a pre-programmed element to insert from the standard email edit menu … but, I’m not sure if that’s possible.
Did that help clarify the question?
