An insurance comparison site improved quote-email deliverability through SEM-driven signup spikes
SEM campaigns drove spiky signup volume of mixed intent. Verifying at the form preserved deliverability for legitimate shoppers.
Persona: An insurance comparison marketplace
What was breaking
Paid search campaigns on insurance keywords drew a high share of fake or careless signups — both bots and tire-kickers. The quote-email sequence was the conversion lever, and bounce rates from paid-acquisition cohorts were tanking the sender reputation that organic-acquisition cohorts depended on.
How emailzeno fit the workflow
Real-time emailzeno verification was added to the signup form, with the SEM landing pages flagged for the strictest policy. Disposable and undeliverable signups were rejected at the form. The cleaner inbound list kept the quote-email sequence deliverable across both organic and paid traffic.
What changed
Quote-email open rates on paid-acquisition cohorts converged with organic. Quote-to-bind conversion improved. CAC payback shortened because the email follow-up that closed the loop actually reached prospects.
“Paid acquisition lives or dies on the follow-up. Verification made the follow-up actually arrive.”

Apply different verification rules to organic vs paid signup forms — strictest for highest-junk channels.
Real-time at scale
Sustained verification throughput during SEM-spike traffic without backpressure on signup latency.
Quote-to-bind attribution
