Keeping a spreadsheet is such a good idea - during my last search I was talking to a dozen different companies initially, and it would have been impossible to keep on top of everything without some sort of organization.
years ago I went further and created a full web app to manage/track. it could manage email templates, send out emails with link tracking, had some ways to keep track of opportunities, let me keep multiple versions of a resume on hand, etc. Was moderately useful, as years before, I'd done 'spreadsheet' stuff, and that was painful. 3-4 weeks, 120+ outreaches, very few replies, etc.
