Specialized conversations are ones the system triggers automatically in specific occasions. These conversations can be customized as needed.

• Default conversation — A default conversation gets triggered when an existing customer initiates a conversation, but the customer's message was not a recognized keyword.

• Expiration conversation — An expiration conversation gets triggered automatically when customers try to re-engage with conversations that have expired.

• Welcome conversation — A welcome conversation gets triggered when a first-time customer initiates the interaction, such as when the customer uses a messenger channel to initiate contact with the company.
