Email Verification Tool

[NickFitz]

What we have found with previous mailings is that some email addresses have bounced where the recipient has left the company, or the email address is just plain incorrect (e.g. invalid characters).

As this should have given you a list of addresses that currently fail, remove those from the list.

Run your next spam^H^H^H^H marketing email run. If some of them bounce, remove those from the list. However, some of the failures may be due to temporary problems with mail servers, so you may not want to remove them immediately...

Long and short: there is no quick fix. It's a complicated business and will require a well-thought out solution. Asking CUK may not be your best bet
