Salesforce Exam B2C Solution Architect Topic 3 Question 13 Discussion

Northern Trail Outfitters (NTO) is at the beginning of an implementation of B2C Commerce and is now discussing the communication flow. They are designing the flows between systems to send password resets via email when a new account is created in B2C Commerce or the email address is updated.

Considering NTO also uses Service Cloud and Marketing Cloud, which feature should a Solution Architect suggest to optimize the end-customer experience while also ensuring that tracking is visible to service agents?
