Domains, warmup, ramp curves and the mailbox math behind a sending setup that survives a real campaign.
A domain reputation check reads a rating that mailbox providers assign after the fact, from mail you have already sent. On a new cold email domain it is usually blank, and Google is retiring the dashboard most people mean by it.
An email deliverability consultant is worth the money when the rejection names a configuration or reputation fault. When messages arrive and nothing happens, the problem is who you wrote to, and no consultant can fix that.
An email deliverability service works on the sending: authentication, domains, reputation and pacing. It has no view on who belongs on the list, and Google states plainly that no provider can guarantee the inbox.
Warmup is a ramp, and the thresholds it ramps toward are deliberately unpublished. What Google and Microsoft actually say, and why we will not quote you a days-to-warm figure.
The three records authenticate your domain, and that is all they do. What each one proves, what none of them can tell you about the store you are emailing, and why we will not quote you an inbox rate.
