Excel vba macro for multiple matching cells detection

I am implementing a macro that checks column E for dates that are 7 days away from current date.
If cell date - current date = 7
then an email containing the row that has the matching cell, is sent to an email address to notify.
This is my coding it works succesfully, except for one issue.


Sub Workbook_Open()

Dim rngStart As Range
Dim rngEnd As Range
Dim rngCell As Range
Dim strHtmlHead As String
Dim strHtmlFoot As String
Dim strMsgBody As String
Dim strMsgBody1 As String
Dim strMsg As String
Dim objEmail As Object
Dim OutlookApp As Object
Dim OutlookMail As Object

'On Error GoTo ErrHnd

'only run if between midnight and 2AM
'If Hour(Now) < 2 Then

'setup basic HTML message header and footer


'setup start of body of message
strMsgBody = "The following task(s) are due in less than 7 days :"

'Worksheet name
With Worksheets("Sheet1")
'set start of date range
Set rngStart = .Range("E1")
'find end of date range
Set rngEnd = .Range("E" & CStr(Application.Rows.Count)).End(xlUp)

'loop through all used cells in column G
For Each rngCell In .Range(rngStart, rngEnd)
'test if date is equal to 7 days from today
If IsDate(rngCell.Value) Then
If rngCell.Value - Int(Now) = 7 Then
'add to message - use task name from column A (offset -3)
'change as required
strMsgBody1 = strMsgBody & "
" & "
" & "Task: " & rngCell.Offset(0, -3).Text _
& " is due on " & rngCell.Text & "
" & "
" & "Therefore please take necessary action"
End If
End If
Next rngCell

'Note last test time/date
rngEnd.Offset(1, -3) = Now
rngEnd.Offset(1, -3).NumberFormat = "dd/mm/yy"
End With

'put message together
strMsg = strMsgBody1

'test message
'MsgBox strMsg

'create the e-mail object


Set OutlookApp = CreateObject("Outlook.Application")
Set OutlookMail = OutlookApp.CreateItem(0)

With OutlookMail

.To = "[email protected]"
.CC = ""
.BCC = ""
.Subject = "Task Alert"
.HTMLBody = strMsg
.Send
End With


Set OutlookMail = Nothing
Set OutlookApp = Nothing

Application.DisplayAlerts = True
Application.ScreenUpdating = True


'remove the e-mail object

Exit Sub

'error handler
ErrHnd:
Err.Clear

End Sub


It works succesfully, except for one issue.
when there are 2 or more records with the same date that matches the criteria cell date - current date = 7.
Then only one record is displayed in the email and sent to the email address.
For example there are 3 records as shown below.

Only the 3rd record is detected and attached to the body of the email.

I need to know why this happens?

How can i edit my code to correct this?

I have solved the issue.
Now i have one final issue

It works succesfully, except for one issue.

When no dates fulfill the criteria

rngCell.Value - Int(Now) = 7

An email is still generated without specifying any tasks.

i want to edit the code so that no email is sent when there are no dates fullfilling the following criteria

rngCell.Value - Int(Now) = 7

How can i achieve this?
