Why Verify?

Validation is not Verification.

Normal email validators check to see if the email address submitted is syntactically correct, but don't actually check to see if the address is real.

Asking customers to confirm their email address is effective at weeding-out spam registrations, but has been proven to substantially reduce conversion rates.

Spam registrations and bot signups can pollute your user-acquisition metrics, and spam newsletter signups can pollute your mail server IP space, leading to low deliverability or even service suspensions by your mailing list provider.

Try it Yourself!

Test Addresses


You can test your own email addresses or the test addresses to the left. "Plus addresses" like will also work.

More test addresses are available in the docs.

Even if your forms have not (yet) been plagued by spammers, think of email verification like monetizing a typo. A user that mistypes their email address is one that may be lost to you forever, since you can't email them to ask for the correction. Our drop-in JavaScript Verification API makes sure that doesn't happen.

Whether you're a new startup, a Fortune 500 company, or a mom-and-pop shop just getting started on the web, a blogger, vlogger or email marketer, it's never been easier (or cheaper) to make sure every email address you collect is valid.

Why Certify?

Certifying email addresses using our server-side REST API allows you to make absolutely certain the email address was verified by us.

Certifying email addresses is important if you have concerns that users may be disabling JavaScript or spoofing your forms, or if your forms are being abused by bots (which often ignore JavaScript). The server-side Certification process compares the submitted checksum to our recorded checksum to confirm that the address has actually been validated.

Best part is, your first 5,000 certifications per month are included in your $10/month unlimited verifications, and only $0.001 per address for every additional address. Plus, you only pay for "good" addresses.
