High Speed Verifier
High-speed software designed to check e-mail address for existence.
High Speed Verifier (HSV) is capable of checking thousands of addresses per second. It can easily deal with mailing lists containing tens millions of addresses; moreover, it is with this list size that the program's highest performance can be achieved.
High Speed Verifier detects about 20-30% of invalid addresses in a mailing list, though theoretically it is possible to detect up to 60-70% using a software product. This figure seems relatively small, but actually, it might make 10% of a list. Besides, HSV provides for optimal checking mode in terms of time and data traffic. More thorough checking (with which the rest 40% of invalid addresses could be detected) takes 10 times longer and requires 5 times greater traffic for each address, hence it's not that advisable with huge lists.
High Speed Verifier is offered as a solution for quick removal of garbage from lists with millions of addresses checking by DNS existence of mail servers. Growth of the HSV operating rate with longer lists is ensured by the fact that HSV stores the results of all queries to DNS servers in RAM cache, so, with longer lists the rate of cache hits is greater.
High Speed Verifier is the first professional software designed to check huge mailing lists, it is created by professionals for professionals. We hope with HSV your business will be more effective and successful, and you will enjoy using our product.
