  description: 'Trait Groups are the organized containers used to group related facts about a profile, such as contact details or account preferences. Trait schemas within each Trait Group must be defined before customer information is ingested into profiles.


    Out-of-the-box trait groups like "Contacts" are available by default to help store identity information consistently across channels. Custom groups can also be created to store industry-specific information or satisfy unique business needs.'
