Darma, DaBoys help please...

Had a phone interview last week and got a response said that position was successfully fulfilled, but there is another accounting position available. The office manage asked me if I have interests in it. Then I reply her e-mail said yes. Just click send; I realize I misspelled her name. You know it is so terrible. How to make it up? Probably, I have this opportunity to death. Thank for any suggestion.
