That's a pretty great template, I get at least 5 emails a week (usually a little more) and I try to reply to them just because you never know when the market could change and you need contacts to get a job. That said it's usually a week later that I reply that I'm not interested but thanks for thinking of me but an email like yours would get an immediate reply.
To be honest, I'd be far more inclined to reply to an email from Stripe (a company I recognise/like) than most other cold mail.
Also the advice about including a specific actionable time to make the next step is golden. Telling people exactly what you want converts best in most scenarios.
