YouTube Collaboration Pitch Writer Prompt

Write a collaboration pitch email to the creator below.
Rules:
- Subject line under 8 words, no "opportunity".
- First line: what's in it for THEIR audience (not yours).
- One sentence on why this collab is a fit (shared audience, not shared size).
- Propose a specific format (guest, cross-over, joint live).
- End with a low-friction ask (a 10-min call), not a commitment.
