Email Validation Guide

Check if an email address is deliverable using our Email Validation service.

Available Information​

The following information is available when you send an address to our Email Validation Service.

Can this address receive emails?​

The most important attribute we return is called the result. This indicates whether you can expect an email address to be valid. The result can be Deliverable, Undeliverable or Unknown.

  • Deliverable. Emails are received by the intended recipient.
  • Undeliverable. If you receive an "undeliverable" notification for an email you sent, it could be because the recipient's email server is temporarily unavailable or experiencing high volume, or because the server could not be found. If the server is temporarily down for maintenance or some other reason, you will need to wait to resend the email. However, if the email continues to bounce back, it is possible that the server is no longer in operation.
  • Unknown. No data is availbale for this mail address.
