The unregistered version of Mailing List Wizard is almost fully functional. However, it has one limitation — it process first 250 lines of mailing list only. Also, we can provide only limited support (and with low priority) to unregistered users.

When you'll register, you'll get the registration key (serial number) which will remove the limitation. Your registration key will work for all future versions of Mailing List Wizard (or we may provide you with the new key, if the keys will be changed for some reason).
