Aweber, if the FROM email address contains marketing related words eg @money,will emails go to junk?

I don't know the answer to this but they might. The authorities don't like us sending people anything that can help them make more money.

They want people to rely on the 'system'

In Aweber as you know there is a spam score option. You can understand it from there how much your email seems to be spam.
From the other hand, no matter if you write money, free or other terms that are considered to be spam. Generally they differ from the sender, how much the sender is reliable and then it's considered to be spam. It does not have to do anything with it. If you have collected your subscribers with an opt in form than the mails that you send will be in their Inbox. If you send mail to people that are not in your list than no matter whatever you send it can be in the spam folder or Inbox. You can't know this. In order to understand it, open a gmail account, then send your mail to this address and you will see where it goes.

I say gmail because gmail has the best spam filter. If it was only considered as spam the mails you send where it includes the words make money, free etc... Then you should find all your mails about these subjects in your spam Inbox. Aweber has a spam score, if your mail doesn't exceed the score of 5 than just send it.
