How do I cope when the technical work goes past what I understand?

You can run the campaigns and the reports, and you get lost when the attribution breaks or the tech stack tangles past what you actually understand. That out-of-depth feeling isn't a sign you're a fraud. Marketing ops sits on top of complicated, half-documented systems that nobody understands completely, including the people who built them. When you hit the edge of what you know, the skill isn't already knowing. It's tracing the problem calmly. Where does the data start, where does it break, what changed recently? Pull the thread one step at a time instead of staring at the whole tangle. And ask, the engineer, the vendor's support, the colleague who set it up. In this field, knowing who to ask is as valuable as knowing the answer. Keep notes each time you untangle one of these, because the same knots recur, and next time you'll be the one who remembers. The gap between what you run and what you fully understand narrows every time you push into it instead of routing around it. What feels over your head now is just tomorrow's routine, not yet learned.
