There are many types of business, and even a wider variety of customers.
No matter what type of business you’re running—online, actual brick and
mortar, small business, large business—you have to have a way to stay in
touch with your current customers and potential customers. Practically
everyone has an email account. You can probably count on your hands
the number of your customers that don’t have one. For that reason,
building an email list is one of the most effective, inexpensive ways to grow
your business.
