Loops: Newsletters Tool

Loops is built for founders who actually ship product updates and onboarding sequences, not for blast-and-pray newsletter shops — the visual editor and native product event tracking mean you can wire up behavioral emails without touching Zapier. Freemium tier gets you going fast, but the real play is using it as your onboarding engine once you hit product-market fit; where it falls apart is if you need heavy segmentation logic or you're doing demand gen at scale (grab Klaviyo or HubSpot instead).

Best in stack with product analytics tools like Amplitude or Mixpanel where you're triggering emails off actual user behavior.
