Domain statistics you can act on
Watch per-domain throughput, queue depth, latency, deferrals, and bounces in near real time. Spot bottlenecks early and fix them before they impact delivery.
Powering ~120M emails each week for senders across the globe.
Sending made visible
See the health of your sends at a glance — per domain and IP — so you can spot issues and act fast.
Throughput & latency
Messages/min and handoff time to each provider — by IP and domain.
Queue health
Live queue depth, retry counts, and 4xx deferrals so you spot bottlenecks early.
Provider breakdown
Gmail/Microsoft/Yahoo views with response codes (2xx/4xx/5xx) and reasons.
Human escalation
Phone or email. An engineer helps read the logs and adjust pacing.
Real-time send logs
See your traffic as it happens — minute-by-minute events with timestamps, provider replies, message IDs, and retry status. Filter by IP, domain, campaign, or provider to isolate issues fast.
Better decisions with data
See the signals that matter — per domain, provider, and IP — so you can diagnose fast and scale safely.
