Instagram

Picture a hotel concierge desk with a single rule taped to the counter: only answer people who ask a question first. No cold calls, no unsolicited pitches shoved under doors. That’s roughly how Instagram DM automation is supposed to work — a system that reacts the instant someone raises a hand, and stays silent otherwise. It looks like magic when a creator says “comment GUIDE and I’ll send it to you” and the resource appears in your inbox seconds later, but underneath the trick is a fairly narrow, rules-bound piece of engineering, not a mysterious growth hack.
