We have just released a new website - Bulk-Email-Verifier.biz. The service basically offers email cleaning for mail lists of any size. We will be happy to get some feedback. The basic ideas behind this project: Offer a very simple interface that will be super simple to use. This included ability to upload very large lists at once, without requesting the users to divide their tasks to some smaller tasks. Present results in the most useable form - avoiding any form of custom classification of results. Just tell if email is valid or not and whether it is hosted on disposable or catch-all domain. Only take money for what use actually uses. This is about having no monthly fees and no big packages that the users must buy but won't use. Offer one of the lowest prices on the market. We have compared prices of competitive services and put our pricing on the lowest levels. I will be happy to provide some extra free requests if someone is willing to test the functionality beyond what our free trial provides. Feel free to contact me for this.
