A food-delivery marketplace cut newly-acquired-address bounce rates by 75%
Restaurant partners and customers signed up across countries and languages. Automated verification of every new address kept lifecycle email viable at marketplace scale.
Persona: A European food-delivery marketplace
What was breaking
Address quality varied widely by acquisition channel: organic web signup, app onboarding, restaurant-partner referral, and acquired competitor lists from market consolidation. Lifecycle email was the cheapest growth lever, but bounce rates on legacy and newly-acquired segments were undermining sender reputation across multiple country domains.
How emailzeno fit the workflow
Every newly captured address — whether from web, app, restaurant intake, or M&A imports — was fed through the emailzeno API on capture. Existing legacy segments got a one-off batch sweep. Country-level reporting let the team see per-market deliverability rather than averaging across the network.
What changed
Bounce rate on newly-acquired addresses fell sharply. Lifecycle email returned to a positive-ROI channel in countries where it had been quietly losing money. Per-country deliverability reporting became a standing slide in the weekly growth review.
“Country managers used to fight us on email frequency. Verification gave us per-market data they could trust.”
