List building the wrong way?

So I have just about read everything there is to know about list building. From the "proper ways" to the improper ways. Is there really an improper way to build a list?
If your bringing people into Aweber than really that's the main focus is to get people to sign up. I think an improper thing to do while list building would be emailing your people hourly or spamming them with items they didn't want to be part of.

If they signed up for a free dog training lesson and you give them an email on how to make money online... Your just asking to get reported as spam. Don't do this, stay focused and organized with your email campaigns. You need to keep every email going out in it's place. Don't go off topic, stay with your people, after all they are your bread and butter.

I am doing free ebook give-a-ways right now on many different subject, but all these subject have a basic key ingredient... Making Money Online... So this allows me to pretty much have my emails going out, to be all about making money. It's easy as that, just stay focused and you won't lose.

My ebook are all free and there are 22 of them, they are small reports on ways to go about making that money. From of course list building all the way to SEO optimization. Which everything in between are dealing with making your fortune.

Stay the path, don't have your readers reporting you for spam, stay on subject.
