Ensure your e-mails inboxed, always!!

KleanMail is a cloud based e-mail validation tool that helps you to cleanse your customer database. It can help you identify the valid and invalid email id’s thus helping you ensure that you send emails only to the right contacts. Not only does this save you the additional costs spent on bounced emails, but more importantly, this effectively saves your domain/ip from being blacklisted by the majority of the email service providers. This would ultimately increase the chances of your promotional emails landing in your customers’ inboxes.

KleanMail runs smoothly with no hick-ups. It cleans up thousands of emails with listing the reasons for invalid emails. KleanMail gives excellent results.
