Request Help: Further study on Auto-mail for due date reminder

[samd007]

I had made one excel to send automatic due date reminder mails via Groupwise (made with the help of your forums only).
The problem I am facing is as below:
[Also note, problem is not whether Groupwise or Outlook, problem is its generating multiple emails for each due item]
This is generating multiple emails and even the items not due are generating blank mails.
I would like to generate only one mail with different items different expiration dates.
After that group the identical addressees and compose one message with all the relevant data.
Mail 1: Please take notice of the following expiration date(s):
-Equipment A Job aaaaa expiration date : 19-Aug-12 -394 days.
-Equipment A Job aaaaa OVERDUE : 19-Aug-12 -394 days.
Sent at 17-Sep-13 11:11:04 AM
Mail 3: Please take notice of the following expiration date(s):
-Equipment C Job cccccc expiration date : 19-May-13 -121 days.
-Equipment C Job cccccc OVERDUE : 19-May-13 -121 days.
Sent at 17-Sep-13 11:11:04 AM
And the ones not due, going blank, i.e: the mail body (Mail 2) text reads:
"Please take notice of the following expiration date(s):
Sent at 17-Sep-13 11:11:04 AM"

What I wanted was a single mail with following in the mail body (Example):

" Please take notice of the following expiration date(s):
-Equipment A Job aaaaa expiration date : 19-Aug-12 -394 days.
-Equipment A Job aaaaa OVERDUE : 19-Aug-12 -394 days.
-Equipment C Job cccccc expiration date : 19-May-13 -121 days.
-Equipment C Job cccccc OVERDUE : 19-May-13 -121 days.
