improvement in deliverability and domain reputation
Two energy-saving brands—StopWatt and ESaverWatt—teamed up with Chronos to fix one of the most overlooked revenue killers: poor email deliverability.
Within just 30 days, both brands saw inbox rates climb, engagement surge, and email revenue jump by as much as 56%.
The Story
StopWatt and ESaverWatt sell smart energy devices that help households cut electricity waste and lower power bills.
When they joined Chronos, both brands were sitting on a massive buyer list that had never been properly warmed up. Deliverability was dragging performance down—great offers weren’t even reaching inboxes.
The mission: turn that cold list into a high-performing revenue channel without burning domain reputation.
The Problem
Both brands started with low domain reputation and engagement metrics that risked landing every send in spam.
Unsegmented sends and inactive buyers were suppressing open rates and killing clickthrough.
The team needed to rebuild trust with inbox providers—fast—without losing the ability to scale.
The Goal
To restore deliverability, re-engage past buyers, and make email a top revenue source again.
The focus: build sender credibility first, expand reach second.
The Framework
Chronos applied a three-step deliverability reset:
- Tightened segmentation — Only sent to contacts active in the past 30–60 days to rebuild positive engagement signals.
- Progressive list warming — Gradually expanded reach as open and click rates improved.
- Flow optimization — Turned off underperforming pop-ups and Welcome Flows, and redirected focus to the Fulfilled Flow, which captured 90% of site traffic.
- Conversion-first messaging — Highlighted best deals and proven creatives to maximize immediate ROI.
The Results
The Big Win
When both brands committed to deliverability-first sending, engagement metrics soared—and email revenue followed.
The breakthrough wasn’t a new tool or design—it was better targeting and patience in list warming.
Once inbox trust was rebuilt, both StopWatt and ESaverWatt saw consistent, scalable revenue from campaigns that had previously underperformed.
