We Believe You Deserve Real Users

Easily block bot-signups, invalid e-mails and disposable e-mail addresses.
01. Verify if e-mail is valid

With our API you can quickly verify that an e-mail, or domain should be accepted.

Make sure you only allow valid e-mails to signup! Less spamming, fewer trolls!

02. Block disposable e-mails

Many are stressed by users signing up with fake e-mail addresses. There are multiple services online that allow users a temporary disposable e-mail that only works for a few minutes.

Don't allow temporary e-mails to sign up for trials or other free stuff!

03. Block invalid e-mails

Even if a domain is valid, it might not be able to receive e-mail. This is a common problem with spammers and bot signups.

Block invalid e-mail addresses before allowing them to signup!

Our secure API is free to use

Just verifying an e-mail with a regular expression or blocking specific domains isn't enough. Stop spamming and trolls once and for all.

Our API uses a combination of blacklists and advanced heuristics to check if a domain is valid, or if it could potentially cause issues. The API is free to use for almost everyone, but we have larger plans, if you need to check many addresses.
