About Kilo Health

Kilo Health is a leading digital health and wellness company that empowers individuals through personalized programs in lifestyle, fitness, and nutrition. Their mission is to deliver science-backed solutions that support healthier living, with digital products designed to engage users on their journey to better health.

Email plays a central role in Kilo Health’s communication strategy. It powers everything from account confirmations and program updates to personalized health recommendations. As a main channel for user engagement and retention, email supports the company’s broader goal of delivering meaningful, data-driven health experiences at scale.

The Challenge

Email deliverability at risk

Without validation, Kilo Health struggled with:

Invalid emails hurting performance

During user registration, invalid email addresses slipped into Kilo Health’s system. Bounce rates crept up, and their sender reputation started to take a hit.

Deliverability protection

Kilo Health needed real-time email validation that could block bad addresses before they caused damage. But the solution had to work quietly in the background – without adding friction.

The Result

Kilo Health partnered with Bouncer and saw results straight away:

Reliable email verification

Every email gets verified at the point of entry. This keeps invalid addresses out and gives users a chance to fix mistakes.

Toxicity & abuse scoring

Bouncer flags high-risk emails, including spam traps and toxic addresses, before they hurt deliverability.

Filters harmful contacts automatically

Conclusion

↑ Undeliverable emails blocked

Bouncer helped Kilo Health improve deliverability, keep email lists clean, and protect a strong sender reputation. The solution works in real time, behind the scenes, and supports their mission to provide exceptional digital health services.

Looking ahead, Kilo Health plans to refine validation rules regularly and keep best practices in place for every new project.
