Introducing Transmit: The Glass Box Paradigm
Transmit isn't just another ESP; it's a control plane that shifts the unit economics and security posture of email infrastructure back to the developer.
- Infrastructure Sovereignty: You bring your own AWS SES; you own your reputation.
- Glass Box Architecture: separates the Control Plane (Transmit) from the Data Plane (AWS).
- Zero-Trust Security: No permanent access keys; 100% IAM role-based.
- Cost Arbitrage: Save up to 90% by paying raw AWS rates without per-email markups.
For fifteen years, the email industry has been dominated by "Black Box" providers—SendGrid, Mailgun, and Postmark. They productized the complexity of SMTP, but over time, their moats became liabilities for the modern architect.
The Fracture Point of the Email Oligopoly
"These incumbents built their moats on the premise that email transmission was a dark art requiring obfuscated infrastructure, arbitrary limits, and steep premiums for reliability."
Developers today demand sovereignty. They want to own their logs, their infrastructure, and their sender reputation. They don't want "Contact Limits" or "3-Day Log retention" policies that serve the vendor's bottom line rather than the user's operational needs.
Owner vs. Tenant: The Architectural Choice
Why Sovereignty Wins
Beyond Transmission: The Composable Stack
Transmit positions itself as the "Communication" block in the modern composable web. We don't just send emails; we orchestrate identity and infrastructure.
Infrastructure sovereignty
Owning the infrastructure without the operational burden of raw AWS management.
One-Click Security
Utilizing cross-account IAM Role assumption for a zero-trust architecture.
Automated Warmup
Escaping the SES sandbox with logic-led reputation management.
