Frequently asked questions

Straight answers before you schedule a call.

Do you replace Microsoft 365 or Google Workspace?

For many small and mid-size teams, yes — especially when you mainly need branded mail, aliases, and reliable delivery without a full productivity suite.

Can we keep our existing domain?

Yes. You point MX (and related records) to Northline, then we help you migrate mailboxes during a planned window.

Where is mail stored?

Production mail paths run on U.S.-based infrastructure with encrypted transport and access controls for administrators.

Is there a free trial?

We offer a guided evaluation for qualified teams. Use “Start trial” and our sales desk will follow up with next steps.

Ready when your DNS is.

Tell us how many mailboxes you need and which domains you already own. We’ll send a cutover plan within one business day.
