A fashion e-commerce brand lifted email-driven revenue by cleaning the list before peak-season sends
Drop campaigns and abandoned-cart flows were the top revenue line. A pre-send hygiene pass kept inbox placement strong through Black Friday volume.

What was breaking
During product drops, email volume spiked sharply, and ISPs throttled hard if the list had drifted. Manual hygiene was a Friday-night fire drill. Subscriber-to-revenue ratios degraded quietly as inactive segments accumulated, dragging campaign-level CTRs below the threshold the design team expected.
How emailzeno fit the workflow
A scheduled emailzeno pre-send pass ran on every segment 24 hours before each drop. Undeliverable addresses were suppressed; risky addresses got a lower-frequency cadence. The merch and lifecycle teams used the same hygiene dashboard so segment health was visible alongside campaign forecasts.
What changed
Inbox placement on Gmail and Outlook stayed high through peak season. Email-attributed revenue per subscriber climbed. The lifecycle team stopped firefighting the night before each drop and shipped two extra campaigns per month with the recovered time.
“The drop calendar runs the business. We can't afford a Gmail throttle the night before a launch.”
