Your domain, verified
MX, SPF, DKIM, and DMARC with a status light on every record. The domain goes live only after the zone agrees.
Business email, without the engine in the lobby
Mail for the company, not another inbox tab.
Atrium is the console your team uses — domains, people, groups, calendar, and billing. The mail server stays backstage. Customers never see it.

Your workspace is ready
Outbound stays off until a card is on file.
People, groups, shared mail
Seats, aliases, and shared inboxes. Send-as is explicit. Plan limits are enforced before a mailbox is created.
Abuse is a product feature
Hourly and daily caps, a new-account throttle, and an automatic pause when bounce rate or spam score spikes.

Prices come from the live plan catalog. Seats prorate when you add or remove people.
