Thinking about your E-Mail List...
...makes you shudder with shame because you have bombarded them with sales e-mails before and still have nothing to show for it
...makes you wonder if it has been a good idea at all to build an e-mail list - or has it been a wasted effort?
...makes you wonder if ONE day you would be able to sell to your e-mail list with ease (others can do, too, right?)
