SuperSend Relay provides the power of a self-hosted MTA for high-volume sending, without the engineering overhead or deliverability headaches.
Self-hosted MTA alternatives save teams from hiring dedicated engineers just to manage IPs, domains, and deliverability monitoring.
Scaling a self-hosted MTA past 1M emails/month is an infrastructure nightmare. Managed alternatives are built for that volume from day one.
Poor IP reputation is the top failure point of self-hosted MTAs. Managed infrastructure automates warmup and rotation to protect deliverability.
A self-hosted MTA alternative lets your engineering team focus on your core product, not on becoming email deliverability experts.
Teams choose self-hosted Mail Transfer Agents (MTAs) for one reason: control. The ability to manage your own sending IPs and configurations seems powerful, but the reality in 2025 is that it creates a massive, hidden cost: engineering overhead.
What starts as a simple Postfix setup quickly spirals into a full-time job. You're no longer just sending emails; you're now a deliverability expert, managing IP blacklists, warming up new domains, and debugging cryptic bounce codes. The infrastructure that was meant to provide freedom becomes a bottleneck, preventing your team from focusing on growth.
SuperSend Relay is the infrastructure layer your team has been missing. It's a managed alternative built for teams that have outgrown the operational burden of a self-hosted MTA but still require enterprise-grade volume and deliverability. We handle the infrastructure so you can get back to sending.
The decision to move away from a self-hosted environment isn't about features. It's an infrastructure decision driven by scaling pains and operational drag. Teams typically seek an alternative when they encounter these limits:
SuperSend Relay is not another email sending tool; it's the managed infrastructure that replaces your self-hosted setup. We provide the deliverability and scale of a dedicated MTA without requiring you to manage any of the underlying complexity.
