For businesses with multiple users (e.g., real estate brokerages), CRM AI currently lacks the ability to restrict contact visibility by user.

We need role-based or user-level permissions that allow each agent to:

Access and manage only their own contacts

Not view or interact with contacts belonging to other agents

At the same time, the system must support:

Organization-wide campaigns (brokerage-level emails to all contacts)

Segmented campaigns (targeting contacts owned by specific agents)

This would allow brokerages to maintain privacy and data ownership at the agent level, while still enabling centralized marketing and communication from head office.
