Its like finding people somehow and annoying them to buy a product or services by sending emails which normally ends up nowhere. To answer your second question, Please avoid.
Email marketing is a process to reach out thousands of peoples from digital world through electronic mail.Email Marketing is an effortless, but measurable method to reach out to your customers and engage them. you can use any E-mail marketing tool or service for your marketing efforts.
E-mail marketing is marketing to people on an email list. There is a huge range of effectiveness starting with people who never asked to be on your email list, never learn anything from you, only ever get sales pitches and never buy, through to people who want to be on your list because you offer value in both what you teach and the occasional product you promote.
The delivery rate for bulk email is horrible (even to your own lists). Of the ones that do get through, the open rates are horrible adn are inflated by email browsers that prevoew emails in the inbox thereby telling the tracking system that the email was opened when it may not have been seen by a human. If you use email to stay in touch with your customers and prospects, keep them up to date on your business, tell them about new products, etc., email marketing can be an effective mindshare strategy as long as it is not overdone. It is much less effective, in my experience, for developing new prospects/customers. Not only do email addresses get old fast, but it is hard to avoid the perception of being a spammer by the person who receives an unexpected email from an unkown company.
Aweber.com, mailchimp.com, constantcontact.com are all ESP mailing platforms. Create a Form in the platform, when the user enters there email and OPT's in, then you send them a "Newsletter" and include affiliate offers and thats how you monetize the data.
Email marketing is a type of direct marketing that is used to send advertising messages to an audience. In its broadest sense, each email delivered to a prospective or present customer could be regarded as email marketing.
I think everyone has explained it very well above. If you are new to internet marketing using an autoresponder service is a must have really. But like people have already send above you should use it wisely to connect with your existing customers and potential customers. It's a great tool to expand your business.
