Draft: change this to match how you actually run it.
- The deal page shows when the proposal was opened and how many times.
- If it's been opened several times but there's no reply, a short, helpful nudge works better than "just checking in".
- The Proposal follow-up sequence stops by itself when they reply, accept or decline.
- If they decline, record the reason, then do the quick win/loss review on the deal.
