An address is a destination or identity
An alias may feed an existing inbox. A native virtual address may route into a SalesOS mailbox. Neither is automatically an independent third-party mail account.
An inbox is where conversations live
Connected Gmail and Outlook accounts keep their provider identity. A native SalesOS inbox is a product-level browser inbox, not a claim of public IMAP access.
A quota belongs to the actual account and service
Sending capacity depends on the provider account, message category and confirmed plan. The 36,000-email calculator is an editable planning example, not an advertised included allowance.
Keep the setup review deliberate
The public guide explains the paths. Real connection status, provider access and domain changes belong to the authenticated setup with reviewed permissions.
