well, is there any reason why you keep asking for emails on a site you sell products? Users don't even have time to find out what you sell and they already have a popup on their faces, not a great UX , drop me a mail if you wish ( see profile ), I will review your SEO for free and send you a report, if you feel comfortable with my report, we could go further, if not you can pick someone else, you may also try Patio , but he's most probably overbooked.
We do a lot of web marketing ourselves (just not SEO): This is a pretty proven method in building an email list. We have double opt in and our conversion rate is through the roof. We make a lot of money off of that pop up.
