YES! placeholder tokens should be checked by HubSpot before allowing the user to send the email. It should render as an “empty field” if the HubSpot User doesn’t manually make the change. When our rep told us about placeholder tokens, he used the terminology “templates with placeholder text won’t allow the user to send without filling our the properties” - this was in fact FALSE. It says in the description of the placeholder texts when creating them “must be filled out” - well then the system should obviously check before sending!
