A hospitality marketing agency fixed deliverability for dozens of vacation-rental clients in one rollout

Property managers ran their own intake forms — each with its own data-quality problem. A shared verification layer fixed the source for every client at once.

What was breaking

Each client (vacation-rental brand, regional property group) ran their own intake forms, often inherited from legacy CMSes with no validation. The agency owned the campaigns and the deliverability outcomes — but didn't own the form. Cleaning lists after the fact was a treadmill.

How emailzeno fit the workflow

The agency built a shared verification layer using the emailzeno API and rolled it across every client's intake form as a small JS snippet. Per-client metadata isolated reporting and credit accounting. The agency negotiated volume pricing and resold under their own service tier.

What changed

Across the client portfolio, bounce rates dropped by more than half within a quarter. The agency moved from reactive deliverability firefighting to proactive monthly review meetings — a much better client conversation.

“We sell campaigns. We were tired of having the conversation about why one client's open rate suddenly fell off a cliff. Verification took that conversation off the table.”

The emailzeno building blocks

Per-client tagging

Tag verifications by client; per-client dashboards and per-client invoicing without operating multiple accounts.

One JS snippet, rolled out fleet-wide

A single 5-line snippet works across whatever CMS each client runs. No custom integration per site.

Volume pricing for agencies

Bring the whole portfolio under one bill; price each client at your own tier.

Questions teams ask before adopting

Use the per-tenant metadata field on every API call. The dashboard and exports filter by tenant so client A never sees client B's data.

Yes. The API has no required branding on the client side. Surface results under your agency's own UI.

Delete the tenant tag via API; address data tied to that tenant is purged within 30 days. No reconciliation required.
