I like to try out different safelists to see the results I can get.
Conversion rates from safelists are low but that doesn't mean they don't work.
So anyway, I've been testing a new one out, I joined it about a month ago, and promoted a Clickbank product In the IM niche.
What I do Is write a good subject line, and I keep the post short and to the point.
I find that if you write to long of a post, you will just confuse the reader.
Also you have to have a good product that converts. If you try this, make sure to promote a product In the Internet Marketing niche, and make sure the product really works, or your refund rate will go through the roof at clickbank.
The safelist Is called Million Leads For Free, just search Google for It, they have almost 4 million members.
They allow you to post to 5,000 contacts everyday.
Basically all you do Is login and read 10 messages posted by other members, after you read 10 messages you can post your message for the day.
They don't send emails out to you, you read the messages right Inside the members area by clicking the Message Inbox link.
You could also try a squeeze page to build your list, i have never tried a squeeze page at MLFF.
Anyway, thats all I did to make an extra $225.00 not bad for just goofing around.
