Detection signals
What Email Validation detects
Email Validation confirms whether an email address is registered on Gmail, Outlook, Yahoo, Mail.ru, or iCloud, without logging in or contacting the user. Every row comes back with the detected provider and a clear active or inactive verdict.
Active status
Returns whether the email address is registered on the detected platform (true or false).
Provider detection
Identifies the email provider as Gmail, Outlook, Yahoo, Mail.ru, iCloud, or unsupported, so you can route each row to the right validation path.
Passive, no contact
Reads registration signals only. The account holder is never messaged, logged in to, or notified.

FAQ
Email Validation questions
Can I validate email addresses in bulk? +
Yes. Upload a CSV of email addresses — a minimum of 2,000 addresses per task — or call the REST API, then download a result file with active status and detected provider for every email. You are billed only for successful checks.
Which email providers are supported? +
Gmail, Outlook, Yahoo, Mail.ru, and iCloud. Addresses from other providers are returned as unsupported.
Does the check message or notify the person? +
No. The check is passive and reads registration signals only. Nothing is sent to the address, and the account holder is never contacted or notified.
Is there a free trial? +
Yes. New accounts receive free checks on signup, and every check is pay-as-you-go with no monthly fee.
