some help with landing / squeeze pages

[mixmediana]

Hello IT guys

to promote the affiliate product links is much more useful to build list and use email marketing, I'm hearing about landing page, capture page and squeeze page,, useful to build email marketing lists that will be an asset in the future,

My questions:
1. What is the difference actually between each one of them?

2. I designed a basic landing using blogger, is there any way that I can get the visitor email directly to my email with out using email marketing paid service? I meant some script or codes that works to extract the visitor data [name, email] and submit them directly to my email, then the visitor will get access to the product's page?

3. sometimes, we surf website and suddenly a pop up screen appeared to cover the whole middle screen, asking us to insert name and email this is probably what is called squeeze page, how can I design and make that pop up page, then deliver the extracted data to my email?

As this beginning stage, I'm trying to learn all the tricks to get some solid experience to understand every step of the sales funnel mechanism, how things really work, or what they call it where the magic happen,
Thank you very much for the help, and looking to hear from you soon!
