Two mistakes, one mine one yours. I goofed on the code setting the addresses, you didn't use the variable in SendObject. Try this:
Code:
Dim strSQL As String
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim strEmailAddy As String
Set db = CurrentDb()
'following would be an SQL statement that retrieved the appropriate records. You could also use a query directly
strSQL = "SELECT * FROM [KT VANPOOL DRIVER RECORDS]"
Set rs = db.OpenRecordset(strSQL, dbOpenDynaset)
Do While Not rs.EOF
strEmailAddy = strEmailAddy & rs![E-MAIL ADDRESS] & ";"
rs.MoveNext
Loop
Set rs = Nothing
Set db = Nothing
DoCmd.SendObject acSendNoObject, , , strEmailAddy, , , , , True
That builds an email with this in the "To":
EMAILTEST@1.COM; EMAILTEST@4.COM; EMAILTEST@3.COM; EMAILTEST@2.COM
