About email-validation.org

email-validation.org is a commercial email validation service operated by Inbox Perfection LLC. Despite the .org domain, it is not a non-profit organisation.

What we do

Pay-as-you-go email validation. Check one address, clean a list of up to 1,000,000 rows (CSV, XLSX and TXT), or use the REST API (OpenAPI 3.1), official JavaScript/TypeScript and Python SDKs, webhooks and an MCP server. Credit packs: $35 for 10,000, $49 for 25,000, $79 for 50,000 and $450 for 1,000,000 ($0.45 per 1,000). Unknown results are free. 500 free credits on sign-up. Credits expire 24 months after they are granted. No refunds.

How validation works here

Checks run on specialist email verification infrastructure operated by a contracted provider in the United States. Around it we run the website, the API, bulk processing, billing, our own result taxonomy and support, on the Cloudflare global network.

Every result is one of four statuses with a reason and a recommended action. Results that do not reach a definite answer are marked unknown and never cost a credit. The statuses guide explains each one.
