Note: please be aware that opt-ins are NOT required to answer user-initiated conversations. However, the conversation is restricted to the particular inquiry the user sent - and not extended as a 'marketing' opt-in. In case you wish to message the user after the inquiry has been closed, the opt-in is required. Companies can invite the user during the conversation for an opt-in, during the 24 hour support window.
