Stealth Supply's signup form was converting at 4.07%. Klaviyo's own benchmark badge rated that "Good," and everyone involved treated it as settled. We rebuilt it anyway. We tested formats, moved from a popup to a full page form, and then changed when it fired, from hitting every visitor on arrival to triggering on pages where someone was already engaged. Submit rate went to 12.18%, and the most recent seven-day window is running above 16%. The part that matters more: it now takes about 8 form views to produce a subscriber, down from about 25. Same subscriber volume per day, roughly two thirds fewer people interrupted to get it.
