Safelists are marketing tools that allow you to send messages out to people who have opted in to receive them. Typically you read the mailings and get credits for doing so. You then use these credits to post your own mailings. Sounds simple and it is. But the interesting thing is that this technique works. I have been tracking my results for some time and I consistently get round a 3% response rate.
The secret is to keep posting in a consistent manner. Two big market players have just launched new Safelists. The Timtech guys have launched List Nerd and Matthew Graves, 100% profit mailer. Check them out on my website at http:// drkelp.co.uk by clicking on the respective banners. Good Luck.
