We analysed the results of the hundreds of millions of email addresses we have cleaned to design a new email list-cleaning engine that is more powerful than ever. Try ListWise II for free and take your email marketing performance to new highs.
ListWise is the secret weapon every successful bulk marketer uses to separate the wheat from the chaff.
When you acquire new lists, you rarely have any clues what percentage of those email addresses will bounce or end up as invalid. Of course every list broker will tell you that their list is "double opt in" and "100% clean", but you know better.
Considering you're a seasoned email marketer, you know the cost of sending bulk email to a list full of old, invalid, non-existent email addresses that will generate lots of bounces and cause you and your ESP a lot of grief.
ListWise is a mind-numbingly 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.
Our background in the world of high-volume marketing gives us a real insider’s edge into this business of email address validation.

Getting started is really simple
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 Optimizer, 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.
Yes, in an ideal world, all your customers will be 100% clean, bring clean lists, run clean campaigns, stick to the rules and everyone will live happily ever after...but this ain't an ideal world and you know it.
Don't let the poor list quality of your customers kill the reputation of your IPs.
Remember, it only takes one bad sender to kill your delivery network launching a cat and mouse chase with ISPs to get your emails delivered.
Use ListWise's simple but powerful API to clean your customers' lists before you let them send a campaign.
All you need to do is purchase prepaid credits in bulk, get the API key and start processing records before sending a campaign. You can also try how the API works by signing up for a free account which lets you clean up to 100 emails for absolutely no cost.
Protecting your data is an absolute priority for us. As a company, we are Payment Card Industry Data Security Standards (PCI-DSS) compliant and have very strict internal controls on how data is handled both through our app as well as on the servers the data is hosted on.
