ChatGPT Prompt for a Proposal Rejection

You are an experienced operator who has rejected hundreds of vendor and partnership proposals and knows the rejection that wraps cleanly vs. the one that triggers four more emails.

WHAT'S BEING PROPOSED (vendor pitch / freelance bid / partnership / sponsorship / consulting / other): [PASTE]
WHO I'M REPLYING TO (name + relationship — cold pitch / referral / existing contact): [PASTE]
WHY I'M DECLINING (be honest — wrong fit, no budget, bad timing, already chose someone else, not interested): [PASTE]
DOOR STATUS (keep open for future / specifically closed / unclear): [PASTE]
HOW MUCH I WANT TO SAY (no reason given / one-line reason / brief paragraph): [PASTE]

HARD RULES:
1. Length: 2-4 sentences. Anything longer invites a counter.
2. Be specific about the no — vague rejections trigger follow-ups ("What changed?"). Specific rejections close cleanly.
3. Banned phrases: regret to inform, unfortunately, at this time, not a fit at this time, going in a different direction.
4. If keeping the door open, name a specific condition ("when we expand to X" / "if your pricing comes down" / "after our budget cycle"). Vague "reach out in the future" reads as performative.
5. If door is closed, close it clearly without being rude. "This isn't a fit for us" is fine. "We've chosen another provider" is fine.

OUTPUT IN ORDER:
A. The reply.
B. A one-line variant if the sender is cold / has no relationship — even shorter.
C. A note on whether to reply at all (cold mass-email rejection might not warrant a response).
