If ebooks aren't your jam, create tools instead. I don't recommend a one-or-the-other approach, necessarily, but if you have more development talent than writing talent, this may be a more attractive option for you. These tools can be valuable enough to some of your website visitors that they'll trade you their email address for a free demo of the product you built. Then, for your first email, ask them what they thought of the tool. It's the perfect icebreaker.
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.
You have probably heard before that “print is dead”. However, the data proves otherwise. Not only are people almost 4x more likely to open direct mail versus email (Epsilon), the direct mail response rate has actually increased since 2010 (DMA). This means that when done strategically, direct mail is a great way to increase revenue for your small business.
