Catch job changes among my past champions and buyers

My relationship sheet [sheet link] lists past champions, buyers, and friendly contacts with the company I knew them at. Once a week, check each person's LinkedIn profile against the sheet. When someone has changed company or been promoted, update their row with the new title and company and mark them 'moved' with the date. For each mover, draft a short congratulations note — save email versions as Gmail drafts and put LinkedIn-message versions in the row notes. Genuine congrats first, then a light line about [your product] only if they moved somewhere it could plausibly fit; otherwise keep it purely personal. Don't send anything. Cap profile checks at [60] per run and continue where you left off next week. Summarize movers found and drafts created.
