Email Verification

CDYNE Email Verification is a powerful Web Service used to verify and cleanse email addresses.

Email address hygiene plays a role in effective and efficient email delivery. The CDYNE Email Verification (CEV®) will check the validity of email addresses in real-time as a Web Service. It is important to maintain a clean mailing list and remove undeliverable emails. Many mail servers block a sender's email domain for repeated messages sent to non-existing email addresses, marking the sender as a "spammer". All your messages sent to that ISP (Internet Service Provider) will be considered spam and you may even be blacklisted.

With the CEV, our clients can instantly identify users that choose to subscribe to a service with a false email address so that they have access to a download or secure portion of a website. The service is designed for point-of-entry processing. In real-time, the CEV connects directly to the SMTP server and verifies the address. CEV connects with SMTP servers and simulates the sending of a message. It then disconnects as soon as the mail server informs the service whether the address is valid. CEV will verify 80-90% of invalid mail addresses.
