Guardrails that matter: traffic shaping and circuit breakers

We're building Rewarmly for sending teams, which means we treat deliverability risk like an engineering problem: detect it early, reduce blast radius, and make behavior predictable.

Traffic shaping

Instead of abrupt changes, traffic shaping helps volume change smoothly over time. It's how you avoid the "everything was fine until it wasn't" curve.

• Controlled changes over time
• Less spiky behavior
• More stable patterns you can maintain

Circuit breakers

When signals move the wrong way, the right default is to slow down - not to push harder.

• Throttling to reduce risk
• Simple pause signals
• Clear status you can act on quickly

We'll keep sharing what we build as we move from early marketing into broader availability.
