Why ListWise
Because you don't want to get blacklisted by ISPs
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.
Because clean data always produces best results
Sending good emails to bad lists is worse than sending bad emails to a good list. We've been around the email marketing game long enough to know that even a marginal difference in list quality can result in a major difference in the final outcome.
Because no one cleans email lists better than us
ListWise is built by CyberCom, the company behind Maxmail, the favourite bulk mail platform for high volume senders. In our experience of sending hundreds of millions of emails per month, we've gained valuable insights into cleaning lists and maintaining list quality.
Our global network keeps track of previously bounced messages and gives us the ability to predict with stunning accuracy whether or not an email address in your list is going to bounce. No one else can give you such valuable insights.
