An important and easy step for online marketing is collecting a list of contacts who are interested in what you have to say and sell
. This is done by giving visitors the option to receive newsletters and syndicated publications (RSS feeds). Email marketing can also be helpful in this regard but you need to make the format of your email conform to a certain legal standard to avoid receiving complaints. Specifically you have to include a function in the email to allow the receiver to stop receiving any further messages from you.
