Did you know that email marketing is estimated to be 40 times more effective for acquiring new customers than Facebook or Twitter and that you’re six times more likely to get a click-through from email campaigns than from tweets? There’s no denying it. Email marketing is a must for businesses.

But how do you get people on your list? One way is to ask for their email when they land on your site, either through pop-up forms or sidebar widgets-usually in return for something great, such as a discount or a free digital gift. Attract web visitors to your contact form on your WordPress website with one of these amazing plugins.
