Just be aware that affiliate marketing with the wrong company can damage your brand. For instance, I started my blog w/ Blue Host because of Pat Flynn’s recommendation – which I am sure he was paid for. I am now on day 5 of my site, and e-mail being down, with NO estimate from Blue Host as to when it will be back up. As a consequence, I wouldn’t buy a thing he suggested or endorsed, because of my experience with someone he put his seal of approval on. Blue Host has a HORRIBLE reputation among the community, and I even wonder if anyone would “recommend” them unless they were being paid.
Email is a great way to deliver other forms of content. With Convertkit, I am able to also create free email courses that can automatically be sent out to my subscribers. This makes life easy because all a reader has to do is sign up, and then Convertkit sends out all the information that they need and drips out the content day by day (or whatever timeframe I choose).
