About Loops
Loops is a fresh, developer-friendly email tool aimed at SaaS: clean API, transactional + marketing email in one, and lifecycle campaigns triggered by product events. The design-forward editor and modern DX have made it a favorite of startups replacing clunky legacy senders.
For SaaS teams who want both product (transactional) and marketing email from one modern, API-first tool, Loops is the standout newcomer.
