Delivery and copy mechanics resolve at 50–100 sends, subject lines at 100–500 per variant, but a reply rate needs ~1,500–2,000 sends per variant before it means anything. If your cap is 200 a week, you can still answer "does it arrive and read" this week — you just can't answer "does the offer work" this quarter, and pretending otherwise is how a live offer gets killed on week one. So split it: mechanics now, offer test queued across weeks on one variant at a time, no verdict until the sends are in. Rare knowledge, cheap to take — the skill is free; the campaign it stops you from killing on 200 sends is not: https://axelfreeman.github.io/marketing-mindset/ (`npx skills add axelfreeman/marketing-mindset`). What's your actual weekly send cap — and does your current plan fit inside it?
