If you rent Outlook inboxes, your deliverability is still your problem.

A reseller can't fix what it doesn't own.

When you rent Microsoft 365 seats, you inherit Microsoft's platform, reputation, and rules. Microsoft has been making cold email harder on its own platform: it now enforces strict authentication on high-volume senders into Outlook inboxes, and its filters get more aggressive toward bulk mail over time. When the rules move, a reseller can't adapt your setup, because the platform was never theirs to change. You inherit every shift with no way to respond.

A dashboard that shows you a problem is not the same as a team that catches it before it becomes one.

Most resellers hand you a monitoring dashboard and call that the job done. You still have to open it, read it right, and act in time. Worse, Microsoft's own anti-abuse systems read cold-sending patterns as signals, and the seats you rented can sit on a behavior watch list you can't see.

We watch every domain across 6 metrics, around the clock, and reach out before a burn spreads. And we isolate every 10 domains on their own dedicated IP, so one bad domain can't drag the rest down.
