How to add signature to the email through VBA excel

Hi,

Body of the mail is missing when using the below code. Please let me know how to add signature and the body of the mail should not be missed.

SigString = "C:\Documents and Settings\" & Environ("username") & _
                "\Application Data\Microsoft\Signatures\sign.htm"
                
                If Dir(SigString) <> "" Then
        Signature = GetBoiler(SigString)
    Else
        Signature = ""
    End If
 
  
    On Error Resume Next
    With OutMail
        .To = Range("g6").Value
        .CC = Range("g9").Value
        .BCC = ""
        .Subject = Range("g11").Value
        .HTMLBody = strbody & "<br><br>" & Signature
        .Display
    End With
    On Error GoTo 0
 
    Set OutMail = Nothing
    Set OutApp = Nothing
End Sub
