The following review written by one of the Software Informer contributors applies to version 6.6
GSA Software development and Analytics make excellent software. I own 5 of their tools now and they are updating constantly, some twice a day. This email spider is a top-class extractor that will search the Internet for any keyword you choose and can also search a specific URL for all of the data if that is what you want it to do.
It is very simple to set up, you just choose what you want it to search for, be it emails, names or phone numbers. Then choose your URL or keywords to search and away it goes. It runs very fast and with very few hold-ups, and running multi threaded helps it to keep up with any size job that you can throw at it.
The software also has the ability to send emails. This is by far the best email extractor that I have used and am very pleased with the developer for their amazing ability to keep their software updated and running perfectly, even with the many changes that are happening on the Internet in recent times. They offer a free trial for anyone to give their tools a try and I would suggest you take advantage and give them a go.
