Why Reloop?
Email infrastructure like proprietary platforms—except our codebase is open source. Use our hosted service or self-host it yourself.
The problem
Email wasn't
meant to be a mystery.
Teams shouldn't choose between expensive SaaS vendors and fragile home-grown SMTP hacks. There's a third path.
Opaque vendors
Proprietary providers hide routing logic, pricing surprises, and deliverability decisions behind dashboards you can't audit.
Vendor lock-in
Your contact lists, templates, and sending reputation get trapped in someone else's platform—with no clean exit.
Data leaves your network
Every message, webhook payload, and contact record passes through infrastructure you don't own or operate.
Our answer
Infrastructure
you control.
Reloop is a full email stack—transactional, campaigns, SMTP, analytics, templates, webhooks—under a license you can actually read.
Read the source
Apache 2.0 licensed code you can inspect, fork, and run. Every routing decision is auditable.
Self-host anywhere
Docker Compose, Kubernetes, or bare metal—deploy on your network and keep data where you want it.
Built for developers
Modern APIs, typed SDKs, webhooks, SMTP relay, campaigns, templates, and agent-ready inboxes in one stack.
