A gaming media network protected its newsletter program through a registration surge
Console launches and game-release weeks doubled signup volume overnight. Real-time verification kept the newsletter list deliverable through every spike.
Persona: A gaming and entertainment media network
What was breaking
Registration spikes correlated with major game launches — and so did bot signup attempts trying to claim launch-day content. The static blocklist couldn't keep up with new disposable domains. Newsletter open rates dipped through every spike, dragging the program back to baseline only after weeks of manual hygiene.
How emailzeno fit the workflow
Real-time emailzeno verification was wired into every signup surface (newsletter, account creation, gated content). Disposables and known-bad addresses were rejected at the source. The team added a once-a-quarter batch sweep of the historical list to clean addresses that predated the integration.
What changed
Newsletter deliverability stabilised. Open rates held steady through subsequent launch weeks instead of dipping. The editorial team gained confidence to expand send frequency without risking the sender reputation they'd built over years.
“Every console launch used to set our newsletter program back a quarter. Now launch weeks are a tailwind, not a tax.”
