As with any online marketing, you absolutely must build an email list in order to market as effectively as possible. This is especially true if you’ll be releasing more books in the same niche or genre. However, even if you have only a single book, email marketing can be beneficial for you.
It takes, on average, three times of seeing an advertisement for something before someone buys. Thus, if you manage to get them on your list, you have more chances to encourage them to buy your book.
You can get people to opt-in to your list by simply including an opt-in box on your blog or website, but if you give something related to your niche or genre away, (such as a book excerpt, a short story or a report) you will get more people to subscribe.
Once people are on your list, you can not only market your own book, but books by other authors in the same genre as well as related products. For example, if your book is about weight loss, you could market affiliate products like diet supplements and exercise equipment.
