Mailing List Wizard (also known by its acronym MLW) is a tool that will help you (and guide you) to manage your mailing lists, in order to have them optimized.
Among the different tasks carried out by the Mailing List Wizard are the following: delete all those email addresses that are duplicated, correct address typing errors (for this it uses advanced error detection algorithms), filter the list by different criteria, merge different lists in one, exclude emails that do not meet certain requirements, and so on.
On the other hand, Mailing List Wizard also allows extra information to be extracted from mailings so that it can be reused in other programs.
You can free download Mailing List Wizard 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
