Email Checker Reviews — Discover what people think of this product.

Email Checker is a powerful, developer-grade email validation service designed to help you eliminate invalid, risky, or disposable addresses before you ever hit send. It performs multi-layer verification — including syntax & format checks, domain / DNS / MX validation, SMTP mailbox probing, and disposable address detection — all without sending any actual email. Whether you validate single addresses or large batches, Email Checker gives you rich diagnostics, clearly marking each address as deliverable, risky, or undeliverable. With a clean REST API, seamless integration into any tech stack, and transparent, pay-per-address pricing, Email Checker protects your sender reputation, lowers bounce rates, and ensures more of your messages land in real inboxes.
