Here are some screen shots from the application
This is the main screen...

You can view and edit the e-mail addresses that have been extracted
from your database

You can view the e-mail addresses by domain. This can help
you clean you database up if you see a lot of e-mails with something
like aop.com (perhaps it should be aol.com?).

You can also get a graphical view of the quantity of e-mail
addresses within a specific domain.

and much more...
