The lesson
Name a few brands the recipient respects as your existing sponsors, with one number, and make your ask a look at the schedule.
The subject is "{Their company name} <> Woodpecker", then a congratulation on a new Head of Product Marketing. It jokes about "this cold email sucks, he should have used Woodpecker". The proof line says "SalesLoft, Gong, Salesforce and Chillipiper get 30k sales professional leads each month". The close is "If you're not opposed to chatting...".
Don't copy the unsourced 30k claim. Keep the specific personalization and a named list of peers.
