# Loops
Canonical: https://automationpulse.dev/ja/tools/loops

An all-in-one email platform for software companies, combining transactional, marketing, and lifecycle in one product.

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.
