It would sound fine if you were setting up the other half of a contrast, which is what is going on in your extract, and is one reason for fronting information: to give it prominence.

Hi Tamara

I'd say that you should look at this structure as a structure "for special occasions only". It can be used emphatically. In my example, I think you can also see the contrast that MM mentioned (and that your example also illustrates):

Mary: I've heard a few unusual things about some of the people who work here. Do you know anything about Jane Doe?

Janet: No, not much. She tends to keep to herself.

Mary: What about Sue Smith? Do you know anything about her?

Janet: Sue? Oh, yeah! Her I know plenty about! Just wait till you hear what Sue has done to me! You're not going to believe it!
