martrexo as your email backbone
Fully documented API, dispatched via our own, independent gateway infrastructure. Choose your own HTML or the martrexo block design.
Who is martrexo for?
Every product with an email component needs a matching solution. martrexo becomes part of the product, rather than just an appendage.
-
SaaS providers & product teams: Transactional emails and lifecycle communication from a single infrastructure
-
E-commerce & marketplace platforms: High-volume order and dispatch confirmations
-
Agencies & system integrators: Dispatch for multiple clients from a single shared connection
-
Fintech & regulated providers: High security and compliance requirements for deliverability and logging
-
App operators & webmasters: Deliverability as a fixed part of your own system, without requiring your own email infrastructure
Two approaches, one infrastructure
How you create an email is entirely up to you. In either case, it will be delivered through the same, proven gateway infrastructure.
Approach A: Submit your own HTML
Finished emails are submitted through the API and delivered via the martrexo gateways. The design, layout and content remain entirely in your hands while martrexo takes care of deliverability, logging and reputation protection.
-
Full creative control over the email template
-
Dispatch via our own, independent gateways. No third party in the delivery path
-
Responsibility for cross-client rendering (table layouts, dark-mode display, style compatibility) remains with the submitting party
Approach B: Use martrexo block designs
Instead of finished HTML, structured data is submitted. The same block engine that also generates newsletters and campaigns automatically assembles a fully responsive email from the components.
-
Submission as structured data, in common formats
-
Automatic, pixel-perfect and responsive rendering
-
The same block logic as in newsletters & campaigns, just API-driven instead of manually filled
-
No maintenance effort on your side for client-specific rendering pitfalls
One interface, two approaches, usable in parallel if desired within the same system, depending on the use case.
Docking point
for AI agents
AI agents need tools to work with. martrexo provides these tools via its own MCP server. The platform itself becomes the interface.
- The MCP server accepts requests from AI agents and AI tools directly without separate integration
- Structured dispatch and status information and reporting available
- Not an additional chat feature, but infrastructure that fits smoothly into existing AI workflows
- New features become usable via the same server as soon as they're available on the platform
Operations & reliability
Dispatch runs via highly available, proprietary gateways with no third party in the delivery path. Bounce, feedback and complaint handling run automatically and feed directly into reputation management. Operations and hosting take place in Germany: EU-first as a consistent case for data sovereignty.
Consulting instead of templates
Where more than plain deliverability is needed, strategic design of email journeys is available. Triggers, lifecycle, automation. Not a catalog of templates, but design worked out together with people who understand the given system landscape.
For developers
Integration happens via a fully documented API with clear references for each endpoint. Webhooks return status, bounce and event data directly back into your own systems. Get started without having to deal with major integration hurdles.
Deliverability as part of your own product, not as a side project.
Whether it's stakeholder enablement, a multi-branch system or worldwide dispatch, the best way forward is a conversation that clarifies the specific setup.
