How do you filter out loud feature requests from your actual roadmap?

It's so easy to get sidetracked by the loudest voices in your inbox asking for custom integrations or dark mode. For a long time we treated every request as a top priority just because a few users complained about it repeatedly. Then we realized people usually suggest fixes based on their own narrow workflows instead of looking at the product as a whole.

How do you decide which user feedback deserves a spot in your sprint and which ones are just noise you should ignore?
