What is a list, exactly? Basically, it’s short for email marketing list
or email autoresponder list. These emails are the contact
information of visitors who come to your site who are looking for
specific information on your niche topic.
In order to build a list, you will need to have an email autoresponder
set up.
It is compulsory for anyone who wishes to start an online business
to get an autoresponder account. This will be used to manage your
subscribers and mass email your list with offers and information of
interest.
