Why is it important to remove bad email addresses?

It is important to maintain a clean contact list and remove "undeliverable/bounced" addresses because a lot of mail servers block the sender's IP address/domain for repeated sending of email messages to mail addresses that don't exist. Use GSA Email Verifier to avoid sending messages to "bad" addresses.

Many ISP providers charge there clients for bounce back emails or irrelevant traffic that a bad email address produces. Removing them does not only save you time but also money in such cases.

GSA Email Verifier is an essential tool for email marketing and to avoid ISP's mail servers blocking or banning your email domain because of you repeatedly sending emails to non-existing account holders.

How does the E-Mail Validation work

GSA Email Verifier, the email marketing tool, is quite simple to use. The program connects directly to the SMTP server of the email address to check it without sending the email. It works on the same algorithm as any ISP mail server.
Import the email list you want to verify (import from Outlook, address book, Excel, CSV...)
Click the verify button to start the multithreaded verification process
Export the list again (various formats). This is the cleaned list for later use.

In detail the program works exactly as a SMTP server. MX-Records are extracted from a Domain Name Server (DNS) of the email domain. The Verifier then connects directly to the SMTP server and simulates the sending of a message (nothing is sent to the recipient). A free defineable ruleset in the programs options let the software react on the response given from the server.

These tests drastically reduce the number of bad email returns while increasing the accuracy of a mailing list. There is no need to disturb your clients and friends anymore to check if their email addresses are still valid.
