Validate address format and domain quality, then see disposable, free, and role-based signals. This tool does not confirm whether a specific mailbox exists.
This free email checker scores an address beyond basic syntax: domain validity, mail service signals (such as MX records), and fraud-related flags Greip uses at signup.
It helps you reject malformed or risky addresses before password reset, trial abuse, or referral fraud. It is not an SMTP mailbox existence test and cannot prove an inbox is active.
Results show whether an address is flagged as disposable or temporary, along with free, role-based, and educational provider signals.
Blocking throwaway inboxes is one of the fastest ways to improve signup quality and stop bonus abuse, fake reviews, and multi-account fraud.
Greip validates structure and enriches the sending domain with DNS and reputation signals (MX, SPF, DMARC, and related fields when available).
Use these checks to catch typos, dead domains, and risky providers without claiming live mailbox verification.
Each lookup includes a risk level and recommendation so you can accept, review, or reject addresses consistently.
Pair email scoring with phone and IP checks to harden registration, account updates, and high-value checkout steps.
Automate validation with Greip's email scoring API: disposable detection, domain intelligence, and custom rules in your app.
Read the email scoring API documentation to integrate checks in registration and fraud workflows.
