Focused domain email
Everything needed to launch domain email, without workspace bloat.
MailOreo is built for the narrow job of connecting a custom domain, creating mailboxes, and keeping setup status honest.
Guided domain setup
Scan DNS, detect providers, generate records, and verify public DNS before anything is marked ready.
Real mailbox provisioning
Mailboxes are active only after the mail backend confirms creation. No fake inbox data.
Sender authentication
Sender-domain records, provider-owned DKIM, SPF, DMARC, MTA-STS, and TLS-RPT in one clean flow.
How it works
A setup flow your customers can actually finish.
Users do not touch backend provider consoles. They add the DNS records MailOreo gives them and only see verified states after public DNS confirms them.
