Write from facts rather than momentum
Pause long enough to remove accusations, assumptions, and details that belong to someone else. For a message about how to follow up after revising a proposal, use this factual base: name the product, proposal, meeting, commercial question, and last agreed next step.
Offer a proportionate next step
Match the size of the request to the relationship and to what the recipient can reasonably decide now. Add one relevant update and ask whether to proceed, defer, change scope, or close the opportunity. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Protect privacy on both sides
Do not hide an unsubscribe request, invent scarcity, or escalate around the named decision maker. Follow privacy, consent, procurement, and recordkeeping rules for commercial communication. Use the most private legitimate channel available and do not share the exchange to recruit support or pressure.
