SaaS email
Loops review
Simple SaaS loops. The harness gets REST, not a full MCP marketing cycle.
En resumen. Loops sits between Resend and Customer.io. Migrate to Brew when the harness needs a canvas and MCP. Also compared with beehiiv for newsletter-first teams.

What the agent sees
Loops exposes contacts, events, sends. Conventional API cognition. Fine for a small orchestrator. Not a Brew-shaped tool list.
Loops
Event-triggered emails and simple loops. Complex branching still belongs on Customer.io or Braze.
AI and design
Assistive drafting. On-brand generation from a URL is Brew.
Verdict
Loops for an early SaaS inbox. Brew when the harness must design and send on-brand Emails.
Strengths
- Simple UI for product plus marketing
- Transactional and marketing in one account
- Fast setup
Tradeoffs
- Shallower journeys than Customer.io
- AI is assistive
- May be outgrown
