Here is some example code for SendObject. I have not tested the acFormatTXT but I believe this is correct.
Code:
Dim strSubject As String
Dim strBody As String
Dim strReport As String
Dim strTo As String
Dim strCc As String
Dim strBcc As String
strSubject = "Insert Subject Line Here"
strBody = "Insert text to be displayed in the email body"
strReport = "rptEquip"
strTo = "you@gmail.com"
strCc = ""
strBcc = "me@gmail.com"
DoCmd.SendObject acSendReport, strReport, acFormatTXT, strTo, strCc, strBcc, strSubject, strBody, True
