Engineered for Zero Downtime Email Delivery
Deep dive into the core architecture powering Solidrix Send: Smart Router, Virtual SMTP Proxy, Redis Quota Manager, and Solaris AI.
Smart Gateway Router
Solidrix Send dynamically evaluates every outbound email against per-gateway priority weights, cost thresholds, and remaining daily/monthly quotas. If Gateway A experiences temporary rate-limiting or downtime, traffic automatically cascades to Gateway B without client application retry errors.
- ✔ Priority Cascade & Round-Robin Routing
- ✔ Atomic Redis Quota Counters
- ✔ Automatic ESP Outage Isolation
