Email Verification API

Verify email addresses through single and bulk REST APIs and receive syntax, domain, mail-server, and available delivery signals.

Get started

The Email Verification API supports synchronous single-address checks and asynchronous bulk verification. The single endpoint returns immediately, while bulk requests return a task ID for progress and result retrieval.
