Your #1 online success tool is a listserver. If you don't have one you are NEVER going to succeed online. Here's why.
A listserver is a handy piece of software which enables you, at press of a single button, to deliver a message to every single person on any given list. The listserver is important because list it delivers messages to is important. Indeed, I'll go so far as to say: business is your list, list is your business.
Companies which are making money online are making money because they're 1) building their crucial email list and 2) using a listserver to deliver regular messages to it.
What can these messages be?
* a company newsletter * information about products and services * usage information, so that customers get more value from what they buy * specials, sales, offers, discount coupons, etc..
In short, listserver enables you to run most customer- centered business imaginable, keeping your vital information in front of prospects in ways impossible in "real world" and for a trifling cost.
When you've got a listserver, you're able to wake up in morning with a dandy idea for motivating your prospects... sit down at your computer and write your client-centered message (or reuse a message that has worked for you in past), and, by hitting a single button, get that message out IMMEDIATELY to every single person on your list. Want to update prospects in afternoon? No problem! Create another message and send it out to your list! Your prospects will have it in minutes!
