I've decided to write this post to both help him and anyone else who has this problem.
There's a few reasons why some people have big lists but no sales at all.
1. Bad Lead Source - the place you bought/generated the leads from were bad.
2. Bad Copywriting skills - You might've sent them tons of poorly written sales-pitches which in turned caused them to lose Interest.
3. Too cowardly to E-mail them - if you aren't E-mailing them twice a day, you're a coward and will never make big money from a list.
4. Burnt List - You probably E-mailed them too many offers that the list is now burnt.
5. SPAM - You Probably spammed the shit out of the list and now they don't want to open your E-mails anymore.
6. Email Deliverability - Your E-mails Are Probably not being delivered into their Inbox anymore.
