As a word of advice, if the company is all about clothing products, there is no meaning in placing the opt-in list in a page which explains about cars. Along with this, with the opt-in form, you have to give the customer a reason for signing up with the company. For example, talk about the new products which will be in the market or about the different offers which might attract the customer in the recent future. This will definitely drive better traffic to your page.
Offering free products to the people who subscribe is a common practice today. For instance, consider your company is producing software tools for search engine optimization. Now, you can offer every new subscriber a book on how to improve visibility of the website on the internet or a report on latest updates and rankings of websites. Offering free trials of the company's new product is also a common practice. Sending emails with contests and puzzles regularly can also help the cause. Offer special gifts and vouchers on successfully completing the contests. "Members only specials" are also a good technique to attract more customers to sign up with the company's email address list.
