The Executive’s Personal Email Is Institutional Infrastructure

When providers and advisers rely on an executive’s personal email, the institution depends on infrastructure it does not govern.

The answer

Personal email often survives role changes and feels more reliable than the company account. It becomes the recovery route, deal archive and trusted identity while administrators cannot monitor or revoke it.

Where this breaks

It becomes the recovery route, deal archive and trusted identity while administrators cannot monitor or revoke it.

The operating move

Move institutional authority to named institutional accounts and preserve a controlled personal emergency route only where necessary.

- Institutional uses

- Recovery dependencies

- Records to transfer

- Provider updates

The test

Take the personal mailbox offline. Every blocked institutional action is a governance dependency.
