Optimized sending infrastructure
SMTPeter routes all outgoing traffic through a distributed and continuously monitored sending infrastructure. Delivery responses are analyzed in real time to keep performance high and prevent bottlenecks.
Domain specific policies and pacing
SMTPeter applies per domain policies for queues, connections, and concurrency. It respects the sending limits of each provider and prevents sudden bursts that could lead to deferrals or temporary blocks.
Feedback based throttling and retries
SMTPeter automatically adjusts delivery speed based on responses from receiving servers. When providers slow down or return temporary errors, the platform adapts and retries at a suitable pace to maintain smooth and reliable delivery.
Built in monitoring and visibility
All delivery activity is logged and visible in the dashboard. You can review per domain throughput, deferrals, and bounce information. These insights help you understand delivery conditions and fine tune your sending strategy without guesswork.
