A public contact email helps people reach you; an account-recovery address helps you regain control of important services. They need not be the same. Separate these roles where practical, while keeping both secure and monitored. An address that is less public still needs strong authentication and reliable recovery arrangements.
01
Define what each inbox is for
Use the public inbox for inquiries and customer communication, with suitable delegated access. Keep sensitive account administration and recovery in an appropriately restricted account. Avoid forwarding everything into a shared mailbox without reviewing who can read it. The separation should reduce unnecessary access, not create an abandoned inbox that nobody can recover when needed.
02
Secure the underlying accounts
CISA recommends multifactor authentication as an important account protection. Use supported strong methods and keep recovery information current. Review connected applications, forwarding rules and delegated users after staffing changes. If one inbox receives security alerts for many services, identify who is responsible for investigating those alerts and how urgent messages are escalated.
- List which services use each address for recovery.
- Restrict access to security messages and recovery material.
- Verify suspicious requests through an independent trusted route.
- Test the approved recovery process before an emergency.
03
Example of a growing customer team
A founder originally used one mailbox for public inquiries and domain administration. As staff join customer support, granting everyone full access would expose sensitive reset messages. Move administration to an appropriately controlled account, update recovery settings carefully and provide support access only to the communication it needs. Verify that important alerts still reach an accountable person.
Frequently asked questions
Is an unpublished email address a security guarantee?
No. It can still be exposed, guessed or compromised. Separation reduces some unnecessary visibility and access, but authentication, careful permissions and reliable recovery remain essential.
Should I change every address immediately?
Plan the migration and verify each service's requirements. Rushed changes can lock you out or leave recovery tied to an inaccessible inbox, so keep a controlled record of completed updates.
