Good to know
HubSpot receives player contact details only (user events).
When you connect, Nettla creates a property group called "user_information" in HubSpot for its fields.
Players' marketing choice is sent as opt_in_to_marketing_emails. Only email players where it is true.
To send all existing players when connecting, see "How do I choose which events are sent to an integration?".
