Questions and answers

Frequently asked questions about this download

Is an email sent to the address?

No. The check works with domain lists, DNS records and patterns. The person behind the address notices nothing.

What does is_deliverable mean?

The domain has a valid MX record and can accept mail according to DNS. Together with is_disposable and risk_score, you get the full picture.

How do I decide automatically?

Use recommendation: accept ACCEPT, flag REVIEW, reject REJECT. For your own thresholds, risk_score from 0 to 100 is available.

Can I also check phone numbers and websites?

Yes. POST /validate/all checks email, phone number and website in one call: the number against the international E.164 format, the website for DNS, HTTP and SSL.
