Shoot a quick screencast video… If you’re on a PC, use Camtasia. If you’re on a Mac, use Screenflow. These are tools to record what’s happening on your screen. You can use them to present slideshow presentations or give a tutorial on how to do something on your computer. For example, when I teach WordPress stuff, I turn on ScreenFlow and just record my screen as show people how to set things up. It’s simple.
Create as many subscription widgets as needed and test their performance across your sites. The subscription widget’s intuitive drag-and-drop editor allows customize your forms with a few clicks of the mouse. Edit the layout, text, image, and color scheme order to fit your brand’s visual aesthetic. When you’ve landed on a design you’d like to use, the tool will generate an HTML code to be copy and pasted into your website’s source code.
Include social sharing buttons and an "Email to a Friend" button in your marketing emails. That way, you'll gain access to their friends, colleagues, and networks and expand your contact list. At the bottom of your emails, include a "Subscribe" CTA as a simple text-based link so that the people receiving the forwarded emails can easily opt-in, too.
For effective and actionable results, you should do A/B tests, which test two (or more) different approaches. For example, you could send half of your list one subject line, and an alternate subject line to the other half. You could also A/B test the two approaches with a small subset of your list, then send the winning headline to the rest of the list.
