The Architecture Behind Sub-Second Deliverability
How does Temp-Mail.im deliver incoming emails to your browser tab in under 2 seconds while handling millions of daily messages? Here is our high-performance architecture:
- Custom Go MTA Cluster: Lightweight edge mail servers accept incoming SMTP packets with zero connection overhead.
- In-Memory Redis Pub/Sub: Messages are parsed and broadcast across a distributed Redis event bus in under 15ms.
- Persistent WebSocket Stream: Active client browser tabs receive real-time JSON push payloads without polling lag.
- Automatic 24-Hour RAM Eviction: Volatile cache nodes purge expired mailboxes automatically, keeping memory usage ultra-lean.
