Lettr

Team edits without dev tickets. One API for all emails.

Visit site

Lettr is an email platform for SaaS companies that unifies transactional and marketing emails under a single API and visual editor. Developers integrate once; the marketing team edits emails without filing tickets.

  • Unified transactional and marketing emails: Send both types from one platform with a single API and SMTP. Maintain one sending domain and reputation.
  • Drag-and-drop editor: Powered by Topol, used by 40,000+ companies. Build templates visually with dynamic placeholders, multilingual support, and synced header/footer sections.
  • No dev tickets for content changes: Marketing and product teams independently draft, review, and publish email templates using the visual editor.
  • SDKs and API: Official SDKs for Laravel, PHP, Node.js, Go, Java, and Rust. Clean REST API and SMTP for quick integration.
  • Searchable logs and webhooks: Full-text search across all sent emails. Webhooks for delivery, open, click, and bounce events help debug issues fast.
