This API validates email addresses through syntax checks, MX record lookup, detection of disposable emails, and identification of role-based addresses, along with typo suggestions. It provides a confidence score for the validity of the email address in real-time. The service supports 100 free requests per day and offers a pro tier for larger usage.
Build signup gates that block throwaway emails, clean mailing lists easily, or show users a quick "did you mean" when they mistype their provider. You can call a single endpoint and get back clear fields like syntax, MX presence, disposable flag and a confidence score. Upgrade to Pro if you want live SMTP inbox verification that actually probes the recipient address. The free tier is generous for testing and small projects (100 checks/day).
