Loops
The email platform built for SaaS
Loops is a developer-first email platform designed exclusively for SaaS companies, combining marketing and transactional email in a single clean interface. Built by Y Combinator alumni, it features a Notion-style block editor, event-based automation triggered by user behavior like signups and upgrades, and contact-based pricing with unlimited sends. Its standout strength is letting small SaaS teams replace both their marketing email tool and transactional service (like SendGrid) with one unified platform.
Mailjet
Collaborative email platform for teams with powerful API
Mailjet is a French-founded email platform (now owned by Sinch) that uniquely combines transactional and marketing email under one roof with real-time team collaboration. Its volume-based pricing with unlimited contacts makes it particularly cost-effective for businesses with large subscriber lists but moderate sending frequency. With strong GDPR compliance baked into its European DNA and a flexible API, it bridges the gap between developer-focused tools and marketer-friendly platforms.
