best email validation service free

Product Information

ListWise is an effective online email validation and verification service for businesses. It has been specifically designed for businesses with a bulk-email marketing strategy.

ListWise is a simple tool that intelligently cleans your list, gets rid of duplicates and potential bounces and gives you a clean, fresh list that you can then use for your email marketing efforts.

When you acquire new email lists, you rarely have any clues what percentage of those email addresses will bounce or end up as invalid.

If you attempt to send bulk mail to too many invalid, non-existent, bouncing email addresses then your mail servers, content, as well as all IPs associated with your campaigns could end up on very severe blacklists.
