- Founded
- 2022
Loops (YC-backed, founded 2022) is built specifically for software companies. It consolidates transactional email, marketing campaigns, and lifecycle automation into one product, eliminating the common pattern of running SendGrid for transactional and Mailchimp or Braze for marketing.
Its differentiator is simplicity: a Notion-style block editor, a visual loop builder, contact-based pricing with unlimited sends, and a clean API. Notable customers include Framer, Perplexity, Linear, and Clerk. Transactional is included at no extra cost on all plans.
Trade-off
Loops trades automation depth for speed and ease. If you need heavy branching logic, Customer.io is more powerful; if you want React Email templates, Resend is the pick. For most SaaS lifecycle work, Loops hits a sweet spot.
Strengths
- Simplicity: one product instead of SendGrid + Mailchimp.
- Pleasant Notion-style editor and visual loop builder.
- Contact-based pricing with unlimited sends and transactional included.
- Developer-friendly API with SDKs.
Watch-outs
- Branching logic in sequences is relatively flat vs. Customer.io.
- No native React Email; visual editor only.
- Less mature analytics/automation depth than enterprise tools.
AI features
- Light AI assistance; not a generation-first platform
