Hello! Better is make e-mail responder and send few tips and for ex. after 5nd mail send affiliate link or without e-mail responder ?
That totally depends on your market and what you are promoting. This technique will allow you to capture the email addresses of people that are interested in a subject or product, so you can continue selling stuff to them. Most people say you should give them 6 free emails with tips and put your link in the 7th....but I guess, once again, that it depends on what you are marketing.
