Verbatim from FedRAMP/rules

Providers MUST establish and maintain an email address to receive messages from FedRAMP; this inbox is a FedRAMP Security Inbox (FSI).

Be careful using a personal email tied to an individual for this inbox due to the significant risk to future communications after a change in personnel!
