Why we built OctusRelay

Every business depends on email. Password resets, order confirmations, invoices, onboarding sequences -- when these messages do not arrive, customers lose trust and revenue is lost.

We built OctusRelay after years of managing email infrastructure for our own products and for clients. We saw the same problems repeated: poor deliverability due to misconfigured authentication, no visibility into what happens after the send button is pressed, and hosting providers that treat email as an afterthought.

OctusRelay is part of the OctusCloud ecosystem of infrastructure services. We operate our own mail servers, manage our own IP reputation, and give you full visibility into every message. No shared pools with unknown senders. No black boxes.

What guides every decision we make

Reliability

Our architecture is designed for 99.9% uptime with automatic failover across nodes. When you send an email through OctusRelay, it arrives. Every time.

Transparency

Full visibility into delivery status, bounce reasons, and reputation health. No hidden fees, no opaque pricing tiers, no surprises on your invoice.

Simplicity

Five minutes from sign-up to sending your first email. Clean API, comprehensive documentation, and zero unnecessary complexity. We handle the hard parts.

European infrastructure, built for compliance

OctusRelay runs entirely on European infrastructure. Our mail nodes are hosted across Hetzner and OVH data centres in Germany, Finland, and France. No data leaves the EU.

This architecture ensures GDPR compliance by default and provides low-latency delivery to European and global recipients through optimised routing.
