The most underutilized space on YouTube is the description below the video where you can describe your service and put in your URL that can be clicked through. Add a call to action at the end of the video; for example, “If you liked this video, please click through my link below to find more information.” This is a great way to increase engagement. Also add the Annotations feature from YouTube to create links in the videos. This is very powerful.
Next up is building an email newsletter. The best services offer several ways to do this; you can import your own HTML, start from scratch, or use a pre-designed template. Most of these services have drag-and-drop UIs that let you choose exactly the elements you want to include, as well as image libraries in which you can store assets such as your logo or company photos. Tools that let you test your emails for spam are also essential since there are some seemingly innocuous terms that may send up red flags and drop all of your hard work into your subscribers' junk folders or, worse, get your emails banned before they ever reach their recipients.
