This routine will look at 3 cells within Excel and send a message with an attachment. Sorry, I don't know how to send just a message, but sending a blank xls file is no big deal.
C5=Full email address (JohnSmith@msn.com)
C6=Full path to file attachment (C:\Temp\Blank.xls)
C7=Text message (The routine ran OK) or (Something wrong)
You can create a formula that states what you want.
--------------------------------------------------------
Sub EMailFile()
Application.ScreenUpdating = False ' smooth out macro execution
Range("C5"

.Select ' Start here, where C5=MailWho, C6=MailFile, C7=MailMessage
MailWho = Selection.Range("A1"

' get WHO value from current cursor cell
MailFile = Selection.Range("A2"

' get FILE from current cell + 1 row down
MailMessage = Selection.Range("A3"

' get MESSAGE from current cell + 2 rows down
Workbooks.Open FileName:=MailFile, ReadOnly:=True, UpdateLinks:=0 ' Open the file
ActiveWorkbook.SendMail Recipients:=MailWho, Subject:=MailMessage ' Send it
ActiveWorkbook.Close (False) ' Close and NO SAVE !
Windows("MasterFile.xls"

.Activate 'Now go back to Main file
End Sub
--------------------------------------------------------
I wasn't sure what you mean by "Netscape (no choice)", but I think the above routine will work with whatever has been set as your default Email.
Hope this helps.
