The opt-out/opt-in mechanism itself will continue to work as is. {% endhint %} Your bot template might support out of the box features that require custom content for your particular use case. One of these system features are opt-in and opt-out for Whatsapp. When a user of your bot types 'opt-out' on Whatsapp, the system will no longer allow business initiated conversations to this user. It will reply with the text that is configured in the content section's page "Default responses". The opposite applies for when a user types 'opt-in'. It well then allow business initiated conversations again and replies with another pre-configured response.
