I've been designing and marketing websites and businesses for over 24 years and prior to this I worked in sales, marketing and big business for almost 18 years... which makes me not only old, but also highly experienced at this marketing and Internet stuff.  I've won lots of awards and helped thousands of people, and this website is a testament to the information I share freely to help others succeed online.

An active comments section is a great way to find out which blog post topic piqued your reader’s interest. If you’re lucky, readers may even be so kind as to ask you questions in their comment that you can answer as part of your email autoresponder course, or that you can use as an opportunity later to refer them to your email autoresponder course. I’ve had blog readers email me directly and ask if I could write specific posts to answer specific questions they had. As you can imagine, I’m more than happy to do so.
In fact, Clarity estimates that about 70% of people respond positively when approached about being added to an email list during an offline conversation. Furthermore, Clarity says that emails acquired offline are reported to have much higher click-through rates, sometimes more than twice as much. Make asking for an email second nature, and you’ll quickly grow your email list.  
Rework old copy and make it new. You may have a great post that you wish you could use, but the content is outdated and in much need of repair. There are several blog posts I’ve written that I’ve reworked and slapped a new headline on. The foundation and frame was good; they just needed a bit of remodeling. It is not unusual for us to use a looming new email autoresponder course as the impetus to get us to write several new blog posts for our blog. The topic or idea might be relevant, but the available blog posts at our disposal need rework.
When I'm not designing websites, doing this online marketing stuff or writing. I love nothing more than getting out on a weekend and scuba diving. I'm a qualified rescue diver and love getting wet in the waters around Perth and Rottenest Island. I also cycle, which must be a sight as I'm not the thinnest of people (lol)... and a paddle on a kayak or a swim helps makes most weeks, perfect. At home I have a marine reef tank, which I just love and on top of that I've an awesome dog, called Ziggy.
Longer email course. We have noticed in our own email autoresponder courses that people do unsubscribe more as the course continues, but that does not mean you should not have an autoresponder that runs a longer time. It will take some readers longer to commit to you, your content, and ultimately, anything you are selling. A longer email autoresponder fits their needs perfectly. A longer email course is a good place to feature a set number of blog posts on a topic that you have written many blog posts on.
When creating an offer, a landing page, subscription/sign up form, ask only for necessary information. People really don’t want to be bothered to fill in infinite spaces; in most cases, an email address and a name are more than enough. Ask for more info, and people won’t take time to fill it out, let alone leave their email. To successfully collect email addresses,  keep it short and straightforward.
Basically, it’s a single page site where you share valuable, relevant, and meaningful information in exchange for an email address. It could be anything from landscape photography tips and tricks, low-budget travel tips, monthly entertainment newsletter, free ebook, whitepaper, blogger list… whatever it is your target audience wants and needs in exchange for their email.
Customer reviews are the "social proof" that encourages people to join in on something. It's one thing for you to tell people to sign up for a campaign, but it's another thing for your happiest customers to say it too. Publish your best reviews from communities like Yelp right to your website. This adds genuine value to your landing pages when people are on the fence about submitting their contact information.

Create entirely new content. Perhaps you’re using published blog posts, but your email autoresponder is missing a crucial lesson and you need to write brand new content so that the course achieves its goal. Maybe you’ve not even begun your blog yet, and are building your autoresponder first. Or, you just want to write the course from scratch from the ground up.

iii) List of questions in one email without the answers. Then, you can set up an Email Automation for those who click through your newsletter, to receive another email afterwards, with the answers to the challenges.
