What is the Strategy Behind This Email?

I got this email today:

Hello,
My name is _________, and I write for the (Insert the name of something not even close to what I do) blog at_________
Would you be interested in receiving a guest post submission from me?
What I had in mind was just coming up with an article on theme with your blog and sending it to you for your approval.
I don’t have a specific topic in mind, so I’m happy to write on whatever topic you request, if you have a specific request.

Please let me know what you think, I look forward to hearing from you.
Sincerely,

_________

Seriously? Where is she getting her direction? Is there a strategy here? Did she come up with this on her own? Did a boss tell her that this would work? Let’s assume it’s automated, aren’t there filters so that you can at least focus on certain niche markets? Is this in a book somewhere?

And we wonder why sometimes blogging, SEO and search marketing get black eyes.
Who wrote it?  A puppet?
