Dedicated Inbox
An approach in which a separate email account is created for each AI agent, giving every agent its own address, credentials and storage space. This achieves thorough permission isolation and independent audit trails but entails higher operational costs.
Timeline (last 90 days)
Creating a separate mailbox account for each agent is the most thorough approach to security isolation: each agent has its own address, credentials and storage space, and audit logs are easier to split by agent.
The operational costs of the separate-inbox approach include having to configure, monitor, renew and rotate the password for each mailbox individually, and the speed of manually creating and cleaning up mailboxes cannot keep up with changes in agent lifecycles.
Newly created separate mailboxes often have no sending history, so reports or notifications sent from them easily land in recipients' spam folders; if every agent uses a brand-new mailbox to send mail externally, the accumulation of domain reputation is diluted and overall deliverability actually declines.
It is recommended that externally facing agents (such as customer service and sales) use separate inboxes or API dynamic creation, internally facing agents (such as reporting and alerting) use aliases or shared inboxes, and temporary, experimental agents use API on-demand creation.
