- 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
