Inbox
Sample data, styled exactly like the product — same threads, stars, reply-as-any-address and per-message authentication badges. Nothing here touches a real mailbox.
What you're looking at.
The mock is a stand-in, but every capability it shows is real in the product — and most of it is what a forwarding service or a per-domain mail plan can't do.
One inbox for every domain
acme.app, northwind.io, vela.studio, hey.team — every address on all of them lands in this one list, with threads, stars and search across the lot.
Reply as any address
Open a thread and reply from the exact address it reached — support@, billing@, sales@ — on any domain. Compose lets you send as any of them.
Deliverability, shown per message
Every message carries its DKIM, SPF and DMARC result. The one that failed authentication is already sitting in Trash, flagged automatically.
Your mail app still works
This is the webmail, but IMAP and SMTP ship on every plan — so Apple Mail, Outlook or Thunderbird connect to the very same mailboxes.
Ready for an inbox of your own?
Bring a domain and the first one is live in minutes. Every domain after that is a click, aliases are free on all of them, and deliverability is handled.
