Some of the largest web marketing guru's charge hundreds and even thousands for this method and then deliver to you dozens of videos and manuals... I think that is bull****.
If your real a tight wad, you can make it totally free. Or you can supercharge it with some capital.
Do not be a silly billy and disregard this as some crappy free tutorial. This thing is worth as much as you make it. You have heard this quote a thousand times before:
"Give a man a fish and he will eat for a day. Teach a man to fish and he will eat for a lifetime." - Confucius
STEP #1 - Sign up for Mail Chimp or any other free email list building service & create your campaign ( i recommend mail chimp cos its free and its easy to use)
STEP #2 - Sign up for blogger or any other free website/blog service that allows free hosting domain and commercial use (again i recommend blogger because its idiot proof and allows for commercial use)
STEP #3 - Paste your html code from Mail Chimp into blogger, and then edit blogger so that the code (opt in form) is the only thing visible.
STEP #4 - Promote your Opt In page any way you can. Adwords and FaceBook ads are fast and easy but they cost money. Or you can use any other method you wish such as twitter, seo, youtube, articles yada yada yada.
STEP #5 - umm there is no step 5 - have a cup o tea (add some gin, lol).
