I love this wordpress plugin. It allows you to create professional looking sign-up forms with a few clicks. Not only that, you’ll also be able to install the signup forms anywhere on your blog without any hassle. It comes with easy to edit templates so you don’t need to worry about the designs. What I also love about OptinSkin is it complete with an analytics which you will be able to split test and optimize on the best sign up form.

Because users have different operating systems, web browsers[84] and computer hardware (including mobile devices and different screen sizes), online ads may appear to users differently from how the advertiser intended, or the ads may not display properly at all. A 2012 comScore study revealed that, on average, 31% of ads were not "in-view" when rendered, meaning they never had an opportunity to be seen.[85] Rich media ads create even greater compatibility problems, as some developers may use competing (and exclusive) software to render the ads (see e.g. Comparison of HTML 5 and Flash).
On social media, you’ll only reach a small % of your audience, But with email, your messages are almost guaranteed to arrive in the subscriber’s inbox (unless you’re spamming). SEO works for generating traffic, but most people aren’t ready to buy right away when they come into your website. Plus, you’re really at the mercy of Google. On the other hand, email allows you to follow-up and nurture relationships on a massive scale.
Where they can improve: The automation editor lacks a workflow view, so isn’t the most intuitive to use. List management isn’t the best, either – it doesn’t remove duplicates and lists are kept isolated from another. It also has one of the strictest acceptable use policies, and isn’t ideal if your business deals with affiliate marketing, healthcare products, real estate or novelty products. And it’s certainly not the cheapest provider out there – surprising, given its popularity (which just goes to show the power of great marketing!). Note – we’ve noticed that emails from MailChimp tend to go to Gmail’s Promotions folder.
Many consumers have reservations about online behavioral targeting. By tracking users' online activities, advertisers are able to understand consumers quite well. Advertisers often use technology, such as web bugs and respawning cookies, to maximizing their abilities to track consumers.[60]:60[95] According to a 2011 survey conducted by Harris Interactive, over half of Internet users had a negative impression of online behavioral advertising, and forty percent feared that their personally-identifiable information had been shared with advertisers without their consent.[96][97] Consumers can be especially troubled by advertisers targeting them based on sensitive information, such as financial or health status.[95] Furthermore, some advertisers attach the MAC address of users' devices to their 'demographic profiles' so they can be retargeted (regardless of the accuracy of the profile) even if the user clears their cookies and browsing history.[citation needed]
