[email protected], by tonight.
Domain, mailboxes, and the DNS records that keep you out of spam, set up in one day inside your Business Operating System. Google Workspace, Microsoft 365, or Zoho, pre-configured and connected to everything else you run here.
The problem
Your invoice from a @gmail.com address just lost the deal.
Email is the first thing a customer, a bank, and a vendor check. A free address reads as a hobby, an unconfigured domain lands in spam, and a mailbox outside your operating system means retyping everything twice.
Free addresses fail silent credit checks
Banks, processors, and enterprise procurement treat a custom-domain address as a baseline signal. A free address triggers extra review or quiet rejection.
No SPF, DKIM, DMARC? You're spam.
Receiving servers check three DNS records before trusting your mail. Most DIY setups skip them, and the invoice you sent sits in a junk folder for two weeks.
A mailbox outside your OS is another silo
State notices, bank alerts, and client threads pile up in an app that knows nothing about your entities, deadlines, or CRM.
