Here are some reasons why you need to build a list.
1 Unless you have lots of money for ad campaigns online, it’s almost impossible to succeed in your business without a list. It keeps your business because it’s your direct market in your niche.
2 All a list is, is a list of email addresses you have, or will have, to gather together via opt in pages and other means. You’re not spamming anyone, because they have agreed to be on your list and get emails from you. Those people have made a choice to receive your emails.
3 Hopefully they will pleased with and found useful their freebie they got from you for signing up. This is important as it might be, or close to being, their first actual contact with your information and style of working.
4 Your first few emails in your email campaign then follow up on that in order to lead to a long term working relationship. If they don’t like your style (and not everybody will) they can remove themselves from your list. In fact, it’s better that they do as you only want people willing to become customers and users of your products for their benefit.
