Reloop Email

Reloop gives you the same capabilities as SendGrid, Mailchimp, Resend, and Loops — but the codebase is open source and fully self-hostable.

Transactional email — REST API and SMTP relay for programmatic sending Email campaigns — broadcast and sequence campaigns with audience segmentation Inbound email — receive, parse, and process incoming mail at your own domain Email templates — a visual drag-and-drop editor built for developers and marketers Real-time analytics — open rates, click rates, bounces, and delivery events powered by ClickHouse Webhooks — push delivery events to your own endpoints the moment they happen Contacts & lists — manage subscribers, tags, and suppression lists Workflows — automate multi-step email sequences triggered by user actions API keys & auth — granular API key management with team-level permissions

Use Reloop as a hosted service (Reloop Labs handles the infrastructure) or self-host on Docker, Kubernetes, or bare metal. Same APIs. Same features. Your choice.
