Shared and separate
A contact who unsubscribes from one company’s emails stays subscribed in your
other companies. If one company’s sending is paused for bounces, the others
keep sending.
For example, on a plan with 60,000 emails a month, one company can send 50,000
and another 10,000.
Company or list?
- Use separate companies for different brands or clients. Each gets its own sending domain, footer, unsubscribe page and reputation.
- Use lists inside one company for different newsletters or products of the same brand. A subscriber can leave one list and stay on the others.
Managing clients
Invite each client to their own company in Settings → Team. They see only that company. Companies a client owns themselves use the client’s plan, not yours.Without the dashboard
An account API key or the MCP connection can reach every company you have access to. Pick one with thex-company-id header, or select_company in
MCP. See Authentication.
