Why do I feel like this appears to be a scam?

Text from an email I received -

My name is Erin from Article Writing Services. We have a client who would like to pay you for the opportunity to post some of their content on your website. All of the content is professionally produced and you can select from pieces relevant to your audience.



The result is you get some free, interesting content for your readers while getting paid.


In return our client is asking for one link that they specify at the bottom of the content (no porn or gambling). Feel free to contact me with any concerns or clarifications you may have.


If you would like to see some examples of our content, please email me at erin@article-writing-services.org so we can begin.


Sincerely,


Erin Wallace


Outreach Manager - Article Writing Services
 
I don't know if I should be honored that someone chose to target me and this blog, or that I've looped in with other sites as well.
 
Anyways it looks like the reply went nowhere, so perhaps they've moved on to other opportunities.
