WorldCast is a very powerful tool for validating every email address from a given mailing list.
You don't need to disturb your clients, friends, etc. anymore to check if their email addresses are still valid. WorldCast connects directly to their SMTP server and checks it for you. Nothing is sent to the recipient in the validation process.
The validation process works on the same algorithm as ISP mail systems do. Mail servers e-mail addresses are extracted from DNS. WorldCast tries to connect with found SMTP-servers and simulates the sending of message. It does not send messages in this routine - WorldCast disconnects as soon as the mail server informs the addresses exist or not.
It helps decrease Intent traffic, because you can clean your mailing list beforehand, avoiding to send undeliverable messages that cause a ping-pong of useless messages between SMTP servers. It also helps you save your Intent resources; in other words, WorldCast also helps you save money.
Since it's multi-threaded, the validating process is very fast.
WorldCast is a MUST for discussion list administrators and companies which send catalogues or information to their customers.
