An events agency cleaned up post-event email follow-ups across dozens of brand activations

Each event collected addresses across kiosks, badges, and signup tablets. Verification at intake meant the post-event nurture sequence reached real inboxes.

What was breaking

Live activations meant rushed sign-ups: hand-written addresses, kiosk typos, throwaway emails to claim free swag. The follow-up sequence — the only ROI lever after the event ended — was the first thing the client checked, and bounce rates were embarrassing.

How emailzeno fit the workflow

The agency wired emailzeno verification into the intake tools used across activations. Bad addresses were flagged in real time at the kiosk; a nightly batch cleaned the day's captures before the follow-up sequence triggered. Per-event reporting exposed list quality alongside footfall and engagement metrics.

What changed

Post-event email engagement rose across the board. Clients saw deliverability numbers in their report deck for the first time. Repeat business followed: verifiable list quality became part of the agency's pitch.

“Clients judge our work by the follow-up sequence, not the photo booth. Verification fixed the part of our deliverable we were least proud of.”

The emailzeno building blocks

Kiosk SDK

Lightweight client-side verification suitable for on-prem tablet captures with intermittent connectivity. Queues and syncs when network returns.

Per-event reporting

Tag each batch with an event ID; export a per-event hygiene report alongside engagement metrics.

Disposable-domain detection

Catches the throwaway addresses given out to claim event swag — the dominant junk pattern at live activations.

Questions teams ask before adopting

The kiosk SDK queues addresses locally and reconciles when connectivity returns. Verification status updates in the post-event batch.

Yes. Pass a campaign_id with each verification call; per-tag reporting is available in the dashboard and via API.

You pay per verification, not per event. Most agencies size credit packs to cover their largest activation; smaller events draw from the same pool.
