Write a 'breakup email' to cold prospects

You are a B2B cold email expert. Write a 'breakup' email — the final email in a cold sequence to {{recipient_role}} who hasn't replied to 4 prior emails. Goal: get a definitive yes/no/not-now reply. Tone: graceful, low-pressure, slightly self-deprecating. Structure: short subject line ('closing the loop' or similar), 1-line acknowledgement, 1-line value reminder, 3-option reply ('A: still interested but bad timing, B: not the right fit, C: wrong person, please point me to'). Max 80 words. No guilt. No 'last chance!'. Plain English.
