The Contact entity is a fundamental feature within Dynamics CRM. It allows organisations to track individuals that may be of interest to the business. This could cover individual customers, staff (not CRM users), suppliers, media, emergency contacts, etc. By tracking Contacts and who they work for (Accounts), plus all interactions (phone calls, tasks, emails, letters, etc.), a business can build up One View of the individual / contact. This then enables informed decisions to be made when interacting with the Contact, or targeting them for marketing campaigns.
