CV PDF Tracking and Analytics Software

I’m curious if anyone is using software tools that help send and track CVs and portfolios. Specifically, I’d love to know if they provide insights like whether the documents have been opened, the time spent reviewing them, or if they were shared with others.

Understanding whether clients 1) open the documents and 2) read through the entire CV would be incredibly beneficial. Since I work in the healthcare sector, some physicians have CVs that exceed 20 pages. I’m wondering if adopting shorter versions might improve my response rates.
