Although he keeps on checking through various tools and extensions the daily traffic on his website, which is reasonably good, he is unable to communicate with them, connect with them, inform them about new offers, sales, and discounts or make them a repetitive customer who buys John’s annual or monthly plan with other perks. Upon research, he finds that his website lacks an opt-in form.
He reads about it, selects an opt-in form template and places a small pop up dialogue box at every page of his website, asking people to just subscribe by filling out their favorite genre and email address. In just nine days, he had many web users’ email addresses. John started sending them newsletters, informing them about festival sales and seasonal discounts, and more importantly, he chose a personal touch and started sending new information, book launches and availability of an individual’s favorite genre. John was able to convert many of those web users into subscribed customers. It is a simple example of an opt-in form.
