Unbox.imMultiple domains in one inbox
Yes — you can receive mail for several domains in one place. The hard part is not catching inbound mail; it is sending as the right domain without “via” or “on behalf of” warnings. Unbox gives you a unified inbox and shared queues across domains, with a send identity that matches the domain you choose.
What “one inbox” usually means
Teams rarely want every message dumped into a single personal mailbox. They want one workspace where brand.com, product.io, and studio.co mail all appear, with filters or queues so support@ and hello@ stay separate.
Aliases alone are not enough. If SPF and DKIM are missing for the From domain, recipients see authentication failures even when the message arrives.
How to set it up
- Add each custom domain to the same Unbox account.
- Point MX (and related records) so inbound mail lands in Unbox.
- Create personal mailboxes and shared queues (support@, sales@) per domain as needed.
- When you reply or compose, pick the From address for the brand the customer knows.
Why send identity matters
Receiving works with forwarding or catch-alls. Sending fails quietly: Gmail and Outlook show “via” labels, spam filters distrust the message, and customers lose trust.
Unbox verifies DNS per domain and lets you send as that domain once SPF, DKIM, and related records pass — so multi-domain mail stays consistent inbound and outbound.
Common questions
- Can I see every domain in one screen?
- Yes. Hosted mailboxes and shared queues across your domains show up in one Unbox inbox, with filters so you can focus on one brand or queue.
- Do I need a separate Google Workspace seat per domain?
- Not with Unbox. Plans are based on domains and mailboxes, not a Workspace-style seat for every person on every brand.
