What are your ways to collect feedback and keep a track on it?

During our journey while building Olvy (https://olvy.co/) one of the things that we realised was, users have their own mediums to connect with you as a company with feature requests or feedbacks. Some of them would reach out to us through Twitter, Email, LinkedIn Messages and bunch of them would be on our Discord community. Also, let's say we collate them somewhere, but eventually we lose the track on who gave the feedback from which source, we would like to inform them personally once the issue is resolved. If this happening with us being a small tool. I wonder what happens on the large / mid growth PLG companies. Would love to know your process and thoughts. PS: We have started thinking on this problem and working building something around it.
