If you plan to send a group mail with some newsletter or sale offer or the like to several email addresses, by using an email list available with you or procured from somewhere on the Internet, it is always better to first cross-check and verify the validity of those addresses. Normally many of the email addresses that exist in an email list procured from the Internet would be either fake addresses or expired or invalid addresses. In case you send a group mail to several email addresses, many of which are non-existing or invalid, the emails will return undelivered and there is always a risk of your IP address and / or your SMTP server being blocked if the number of bounced-back mails is large. Therefore, it is better to first validate the email addresses if you have to send some newsletter to a large number of email addresses.
