Proprietary-grade email.
Without the lock-in.

Get transactional sending, marketing campaigns, SMTP relay, and deep analytics without the black box. Run Reloop on our secure cloud or deploy it on your own servers.

SendGrid-level email.
None of the lock-in.

Open source under Apache 2.0. Use our hosted service or run it yourself—same platform either way.

Can't debug deliverability

When delivery drops, you can't see why. Routing and retry logic stay hidden behind a dashboard.

Stuck when you want out

Your lists, templates, and sender reputation don't travel. Switching vendors takes months.

Run it on your terms

Deploy on Docker, Kubernetes, or bare metal. Same Apache 2.0 codebase—your network, your rules.

Your data, their servers

Every message and contact passes through infrastructure you don't own or audit.

Read the code

Apache 2.0. See exactly how emails route, retry, and log. Fork it or ship a PR.
