Your sending domains
are quietly losing
performance.
Email platforms show you campaign-level numbers. Kessio shows you which sending domains are drifting below their own baseline across every program — and exactly what it's costing your deliverability.

Connect your sending data
Add your domains with sent count and replies. Kessio detects your sending baseline automatically from your own numbers, not a fixed industry average.
Baseline builds over time
Every week you check in, Kessio stores a snapshot. After a few weeks your baseline reflects how your specific domains actually perform, not a guess.
Drift gets flagged instantly
The moment a domain drops below its own normal range you see it flagged, how far it's fallen, and what it means for your sender reputation.
7-day trend tells the story
Not just where a domain is today. Where it's been for the past week. Declining for 5 days is a different problem than a one-day dip.
