Email Validation Service
The email validation software that combines SMTP verification, disposable detection, and catch-all checks into one reliable tool. Protect deliverability and stop wasting budget on invalid emails.
Complete Email Validation Software
Every check you need to keep your email list clean and your sender reputation strong.
SMTP Verification
Connect directly to the recipient mail server to confirm the mailbox exists. Not just format or DNS checks. Real mailbox-level verification.
Disposable Detection
Block 190,000+ temporary email domains like Guerrilla Mail, Mailinator, and Temp Mail. Stop throwaway signups before they waste resources.
Catch-All Detection
Identify catch-all servers that accept mail for any address. Know which emails cannot be individually verified so you can handle them separately.
Real-Time API
Validate emails at point of entry with sub-300ms response times. Integrate into signup forms, checkout flows, or any workflow via REST API.
Bulk Upload
Upload CSV, Excel, or text files with up to 100,000 emails per job. Async processing with real-time progress tracking via Server-Sent Events.
Webhook Notifications
Get notified when bulk jobs complete. HMAC-SHA256 signed payloads so you can verify every callback came from MailOdds.
