The problem

Email lists decay at 22% per year. Sending to invalid addresses damages sender reputation, increases bounce rates, and can get your domain blacklisted by email providers.

The solution

Validate your email list before campaigns. Our API checks each email for validity, identifies risky addresses, and returns a clean list ready for your campaigns.

Everything this unlocks.

Reduce bounce rates below 2%
Improve email deliverability by 20-30%
Identify catch-all and role-based addresses
Save money by not sending to dead addresses
