A webinar platform shipped registration filtering as a customer-facing feature
Their customers ran live events. Embedded verification became a product feature that protected both customers' deliverability and the platform's sending reputation.
Persona: A webinar engagement platform
What was breaking
Webinar registration forms were a magnet for low-intent and bot signups: people grabbed the recording link with a throwaway address and never showed up. Customers' invite-and-reminder sequences sent to dead inboxes, dragging engagement metrics on the platform's own sending infrastructure down with them.
How emailzeno fit the workflow
The platform embedded the emailzeno API behind every customer registration form as an opt-in filter setting. Customers could choose to reject undeliverable and disposable addresses at the form, or to accept-and-flag for downstream segmentation. Verification became a marketing-page checkbox feature, not just an infrastructure investment.
What changed
Customer-facing show-up rates improved on filtered events. The platform's shared-IP reputation strengthened because aggregate send volume to dead addresses dropped. Verification became one of the most-adopted opt-in features in the platform's settings panel.
“Verification turned a deliverability tax into a feature our customers actively want.”
The emailzeno building blocks
Embeddable verification
Drop the verification call behind any form your customers configure; per-customer policy lives in your settings model, not ours.
Opt-in policy per customer
Accept-and-flag, reject, or suggest-correction — customer chooses per form. The API returns enough metadata to drive any policy.
Shared-IP protection
Cuts aggregate sends to dead addresses across your customer base, lifting reputation on the IPs you share between tenants.
