You helped them rewrite their mail/newsletter but there are typos all over your blog post. It's worse than a TechCrunch article. This makes me question certain things about your side of the story, the only side available to us.
I personally didn't see any typos. I have this auto correct mechanism in my brain that ignores all the typos (which does have a bad side because I do a lot of them).
I'm not sure what grammar nazis look for in an article. The point the author trying to convey or pointless study of grammar?
