If you have an email box and have seen it full of advertisements, you know that there are basically two different types of email lists - those you want to be on, and those you don't want to be on. In the online world, those are called "opt-in" lists and "spam" lists.
An opt-in list is a list you signed up for and one you can readily get off of. A spam list is one that you have no idea where they got your name or email address and can't imagine ever wanting what they are selling. Opt email lists are the way to go for legitimate, ethical sellers of products and services online.
It is easy to send spam - anyone can do it and it is free. Of course, you can buy a huge spam list for pennies per name, but the list is usually completely useless. It is full of old email addresses, misspelled names, and people who never wanted information about what they are getting. If you want to run a business the right way, you need to start creating an opt email list.
Running an opt-in email list is not as easy as it seems, however. It can take a lot of time and you can get a lot of abuse from people who claim they never opted-in in the first place. By putting your opt email list management in the hands of a software program, you will take a lot of hassle off your plate.
There is one exceptional (and free!) software package that handles opt email list management. It works for small lists and large ones, people new to computers and expert marketers, and does more than just manage the list. Opt-In Revolver helps you create, send, and evaluate test messages to your list to find out just what your customers are looking for.
