The biggest mistake I see serious bloggers making is that they build their email list separate from creating their own products, when in reality the two are completely related and need to happen in tandem.

So many bloggers build up their email lists first (usually in a way that takes forever and totally sucks), and then when they go to create and sell their first product they have the WRONG audience. Yikes.

This is why you need to build your list and create your products in a cohesive and connected way, where it all ties together. When you start with the end in mind, building your list AND your product becomes so much easier.
