Every Email Marketer Needs ListWise

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.

Does your current bulk email sending solution STOP your campaign if a certain percentage of your emails bounce?

Cleaning your email list with ListWise can prevent this!

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 the 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.

Smart Email Marketing

If you're an email marketing service provider, ListWise is absolutely crucial. It could be what will make the difference between your survival or demise as a company.

Because no one cleans email lists better than us

ListWise is brought to you by CyberCom, the company behind Maxmail, the preferred bulk email application for high volume senders. We've gained valuable insights into cleaning lists and maintaining list quality.

Unbeatable Accuracy

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 these valuable insights.

API Integration

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.

How we protect your data

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.

  • As a starting point, only you have access to your data.
  • Any data cleaned through the 'bulk upload' option is deleted after 90 days or immediately after you click on the 'Delete List' icon.
  • Any data being cleaned using the API for email address validation is never stored on our servers.
  • In addition to that, in the live environment, you are logged in through a secure and encrypted screen that prevents your login credentials from being "sniffed" out partway through the login process.

Once you have cleaned your list, we recommend you use our sister service, Maxmail.

Maxmail is the world's most cost-effective bulk email sending solution with no limits and no restrictions. Maxmail ensures your email reaches your recipients' inbox folder!
