Dear Mr. Yoon,
Last time I wrote about you, it was to complain about the unprofessional e-mail you sent me. I've received more e-mail from you since then, and while I would like to give you a silver star for "Most Improved E-mail Campaign," I just can't bring myself to do it.
Why? Because you've turned into a spammer. The first e-mail you sent had no "unsubscribe" link, and I never asked to be on your list. So I wrote to you at firstname.lastname@example.org and asked to be taken off of your list.
The next e-mail I received did include an unsubscribe link, but the link just took me to your homepage, with no instructions on how to be taken off the list. I wrote you another e-mail that you ignored.
The third e-mail, I replied to with a request to be taken off the list, and then I reported you as spam.
The fourth e-mail that arrived today is very irritating. I get a lot of crap e-mail messages, and I end up wasting a lot of time getting rid of them. Since I know e-mailing you won't get me off your list (although I tried again anyway), I'm hoping a nice blog post will get your attention. Maybe this post will be picked up by Universal Hub and then you'll notice it. And then, maybe, you will actually take my e-mail address off your mailing list.
