Start with what you already use
The planned existing-account route brings authorised mail into SalesOS without treating signup as a mailbox migration. Explore Gmail, Outlook or another supported provider in the starting-path preview.
Understand the native route
A browser-native SalesOS inbox on your domain is a distinct setup. Domain ownership, the current incoming-mail route and proposed changes need explicit review in the authenticated product.
Receiving and sending are separate
A mailbox connection may be read-only. Sending requires separate account capabilities, provider eligibility and permissions. More aliases do not create independent quotas.
Make a simple first decision
Choose the business outcome you care about. Your email starting point is optional in early access and can be decided later. No provider login or domain change is required to express interest.
