# List an intake mailbox's existing Gmail aliases

The addresses Gmail already delivers to one of the workspace's processor accounts (its send-as list), read with the account's own grant, so one can be picked as an alias without creating anything.

Access class: `workspace:admin`.

## Endpoint

| --- | --- | --- | --- |
