Bouncer Overview

Bouncer was founded with the mission of making email marketing more efficient and reliable. Early on, our team recognized that invalid addresses were eating into budgets, skewing analytics, and tarnishing sender reputations. We set out to build a platform that’s both powerful and easy to use—no more spinning up servers or wrestling with complex configurations.

Since launching, Bouncer has grown rapidly and now supports millions of verifications per month. We’re proud to serve a diverse client base—from startups to Fortune 500 companies—and have earned certifications like SOC2 and full GDPR compliance. Our commitment to security means your data is hosted in the EU on top-grade infrastructure.

Throughout the years, we’ve added features like Bouncer Shield for form protection, Toxicity Check for identifying risky addresses, and a Deliverability Kit to monitor inbox placement and authentication records. This continuous innovation ensures you stay ahead of deliverability challenges.
