I am a musician that handles several different mail lists for different parts of the country that we play, NOT a spammer. I use it to extract email addresses from email I recieve requesting notices of our play dates, and to send a newsletter regarding upcoming performances. I find this program to be useful and it does what it says it does. I also take issue with all the comments here that are not reviews, but simply angry venting of people frustrated with spam. This developer has been responsive, polite, and obviously committed to improving his product.
To all of you who left poor ratings about this program without actually using it, and bash it, you are no better than the spammers you hate. You're dishonest. Shame on you. This is a forum for REVIEWING SOFTWARE. Not a place to rant about spam.
One bug note: This seems to have a problem recognizing underscores as part of an email address, and it sometimes chops off the address at the underscore.
Otherwise a very useful tool.
