I purchased 'Advanced Email Verifier' by G-Lock Software (http://www.glocksoft.com/)
- To clean my mailing lists of opt-ins. This product promises to provide all 'bad' emails but it cannot really differentiate between good and bad emails.
- The email verification resulted in a list of Bad. I still dealt with a large percentage of undeliverable results.
- MOST importantly though, just running this product got me blacklisted by CBL! There should be a warning when using this software will happen! Do NOT use this product or risk blacklisting!
Please DO NOT WASTE YOUR hard earned money on this crap! Their salespeople will try to convince you it works but that's just not true...I have been duped by them.
