Kickbox
Email verification API.
About Kickbox
Kickbox provides a free API and web tool for checking whether an email address or domain is disposable. The disposable email checker is powered by Kickbox's broader Email Verification API, which draws on a network of email signals to identify accept-all domains, free email providers (such as Gmail and Yahoo), role-based addresses (like help@, sales@, or info@), and syntax errors or typos in email addresses.
The service is aimed at businesses and developers who maintain email lists, such as for marketing campaigns or user registration systems, and want to reduce bounces, spam traps, and low engagement caused by disposable or invalid addresses. It can be integrated at points where email addresses are captured to validate entries in real time.
Kickbox offers 100 free credits to new users to try the service.
