## About

## What it does

Email Verification checks whether an email address is valid and returns a simple result envelope with a numeric `code` and a `success` flag. Send an `email` in the query string and use the response to gate signups, clean contact lists, or reduce bad addresses before you send mail.

Use Email Verification when you need a lightweight validation step in a registration flow, lead form, CRM import, or bulk list cleanup job. It fits into systems that want a fast pass/fail check without pulling in a larger identity or enrichment workflow.

The request schema is minimal: one `email` field. The response schema guarantees a standard wrapper, and the service may include additional module blocks alongside `code` and `success`. That makes it easy to check the outcome while still leaving room for extra response details when they are available.

If you already validate email format at the edge, Email Verification gives you a second check before you store, message, or synchronise the address downstream.
