Positioning
Loops is broadcasts plus event loops for SaaS, with a clean API. When the same brand needs a canvas, automations, and MCP, we point at Brew and the Loops migration.
Agent and API surface
- REST and SDKs for contacts, events, transactional sends.
- Agent-oriented docs. Not a broad MCP tool layer.
Automations
- Event-triggered loops. Broadcasts for announcements.
Deliverability
- Managed sending and simple suppression.
Strengths
- +Low chrome. Generous free tier.
Trade-offs
- -Shallower segmentation than Klaviyo or Customer.io.
Best for
Early SaaS teams that want marketing and transactional in one simple tool.
Consider if
You need deep branching, MCP, or on-brand generation from a site URL.
Pricing posture
Free tier for small contact counts. See loops.so/pricing.
