The Deliverability Mistake Almost Everyone Makes
Most people track the wrong metrics. Health scores. Open rates. Dashboards that look reassuring. None of that actually tells you if your cold email is working. There’s only one deliverability question that matters: Where did the email land? • Primary inbox • Promotions • Spam That’s it. That’s the game. How I Actually Judge Deliverability I don’t guess. I test inbox placement. The simplest way to do this is by sending emails to seed accounts and checking where they land. Here’s how to read the results: Inbox (Primary) You’re good. This is where replies come from. Promotions Not ideal. Usually a copy issue. Spam System problem. Infrastructure, domains, or sending behavior needs fixing.
