Write a breakup email — the final email in my outreach sequence to [prospect name/type].

Context: I've sent [X] previous emails about [topic]. No response.

Rules:
- Open by acknowledging the silence without guilt-tripping: "I've reached out a few times and I know your inbox is relentless."
- State clearly that this is the last email: "I won't fill your inbox further."
- Offer something genuinely useful — a resource, an introduction, an insight — with ZERO expectation of reciprocity
- Close with a permanent open door: "If this becomes relevant in 6 months, my door is open."
- Under 100 words. No emotional manipulation. No countdown timers. No "last chance" language.
- Tone: One professional respecting another's priorities.
