What is Loops?
Loops is a modern email platform built specifically for software companies, unifying the three kinds of email a SaaS product sends — marketing campaigns, lifecycle product email, and transactional messages — in one place. Instead of stitching together a marketing ESP and a transactional API, teams write every email in the same clean, Notion-style editor and keep one contact base with shared properties and events. Loops shines at lifecycle automation: trigger onboarding sequences from sign-up events, send behavior-based nudges, and re-engage dormant users, all driven by API events or integrations like Segment. Developers get a simple API and SDKs for transactional sends, while marketers get campaigns, audiences, and analytics without engineering tickets. A free tier covers early-stage products, making Loops a favorite among indie SaaS and startup teams.

FAQ

Is Loops free?

Yes. The free plan supports up to 1,000 contacts with core features, including transactional email. Paid plans start around $49/month as your audience grows.

Can Loops replace my transactional email provider?

For most SaaS products, yes — Loops sends transactional email via API alongside marketing and lifecycle email, so you don't need a separate provider like SendGrid.

How is Loops different from Resend?

Resend is a developer-first email API, while Loops is a full email platform with campaigns, audiences, and lifecycle automation — Resend sends what your code tells it; Loops also manages the marketing side.
