Sean,
You can accomplish this by doing a VBA routine that is triggered when the date range meets the minimum test.
Here is an example of a VBA routine that launches Outlook and sends an e-Mail
Sub sendMessage(Optional AttachmentPath)
Dim olookApp As Outlook.Application
Dim olookMsg As Outlook.MailItem
Dim olookRecipient As Outlook.Recipient
Dim olookAttach As Outlook.Attachment
' create the Outlook session.
Set olookApp = CreateObject("Outlook.Application"
' create the message.
Set olookMsg = olookApp.CreateItem(olMailItem)
With olookMsg
' add the To recipient(s) to the message.
Set olookRecipient = .Recipients.Add("Christopher Wyke"

olookRecipient.Type = olTo
' add the CC recipient(s) to the message.
Set olookRecipient = .Recipients.Add("Robert Dil"

olookRecipient.Type = olCC
' set the Subject, Body, and Importance of the message.
.Subject = "This is an Automation test with Microsoft Outlook"
.Body = "Last test - I promise." & vbCrLf & vbCrLf
.Importance = olImportanceHigh 'High importance
' add attachments to the message.
If Not IsMissing(AttachmentPath) Then
Set olookAttach = .Attachments.Add(AttachmentPath)
End If
' resolve each Recipient's name
For Each olookRecipient In .Recipients
olookRecipient.Resolve
If Not olookRecipient.Resolve Then
olookMsg.Display ' display any names that can't be resolved
End If
Next
.Send
End With
Set olookMsg = Nothing
Set olookApp = Nothing
