About
Loops puts receipts and password resets, product announcements, and onboarding sequences in one tool, so you aren't stitching a transactional API to a separate newsletter service. Your app sends contacts and events through a small API or the official npm package, and workflows branch on those events and on contact properties without extra code. The free plan covers 1,000 subscribed contacts and 4,000 sends every 30 days with Loops branding, which is enough to launch on, and paid plans start at $49 a month when you outgrow it.
