A: Please let me know about the status of the project.
B: I sent it through your mail long ago. (Just for your knowledge, "long ago" in this context sounds a bit aggressive, since you're calling attention presumably to the recipient being neglectful of communicating with you. If you're okay with that it's fine, but you could also say "a bit ago," or omit it to be polite.)
C: Ok. I looked at it.
