Email R.Evolution
The gateway technology behind martrexo is our own email infrastructure, operated in Germany, available independently and fully managed from the frontend.
Gateway and MTA functionality for developers, apps, and all systems that need to deliver.
Built on state-of-the-art MTA architecture designed for high-volume email delivery, with granular traffic control per destination domain, real-time telemetry and queue management that leaves nothing to chance.
Connected via a fully documented API. That means integration without guesswork, with clear references for every endpoint.
And on top of that, Gateway Analytics, the frontend that turns raw MTA data into a picture with a clarity you won't find anywhere else. Sends, deferrals, bounces, reputation and queue status, live and readable instead of buried in log files.
No third party in the sending path. No outsourced reputation. Deliverability, security and data compliance from a single source.
Gateway Analytics
Every email leaves a trace. Gateway Analytics makes it visible, not as a log-file extract but as a readable picture of what's actually happening to your deliveries.
Delivery status, cleanly classified
Sends, deferrals (4xx, temporary) and bounces (5xx, permanent) are recorded separately and assigned unambiguously. No mixing-up of "arriving later" and "never arriving": Every status means exactly what it says.
Queue and retry transparency
Full visibility into queues and retry behavior. Traffic shaping and throttling per destination domain run automatically, with every step traceable.
Delivery rates by provider
Delivery rates broken down by recipient domain so you immediately see where a domain is acting up, well before it turns into a reputation problem.
Feedback loops and automatic suppression
Complaints are processed automatically, affected addresses are suppressed. There's no manual upkeep and no risk to your sender standing.
Latency, reputation, blocklist signals
Delivery latency, reputation history and blocklist signals are tracked as continuous telemetry live at the frontend instead of grepping through log servers.
SPF, DKIM, DMARC
Full sender authentication by default. SPF authorizes the sending systems, DKIM cryptographically signs every message, DMARC ties both to the visible sender domain. Alignment included.
MTA-STS and TLS
Transport encryption isn't optional; it's expected. MTA-STS enforces TLS with recipient systems that support it and rules out downgrade attacks along the delivery path.
Reverse DNS
Cleanly set PTR records for the sending infrastructure are a basic signal that many receiving systems check, and whose absence causes hard-to-trace delivery problems.
List-Unsubscribe
One-click unsubscribe per RFC 8058 is the standard that major recipient systems expect. Unsubscribes feed cleanly back into suppression.
