Business & domains.

Business email combines an identity people recognize with an account structure the organization can manage. Your domain establishes the address, while mailbox roles determine who receives messages, who can respond, and who can recover access. These decisions become especially important when several people share customer work or when responsibilities change over time.

The business email guide covers people, shared addresses, administrative access, and continuity. The custom domain email guide explains the records behind incoming routing and outgoing authentication. Reading them together helps connect technical configuration with the people authorized to maintain it.

Use this collection when creating an organization’s first mailbox plan, moving a domain to another provider, or reviewing an arrangement that has grown informally. Give each address and sending service an owner. Document recovery routes, verify important workflows, and preserve enough configuration history for another authorized person to understand the system.
