Send a mail when a cell reaches a certain value

Important message to visitors of this page

Ron de Bruin decided to remove all Windows Excel content from his website for personal reasons. If you want to know why, head over to rondebruin.nl.

Luckily, Ron was kind enough to allow me to publish all of his Excel content here.

Most of these pages are slightly outdated and may contain links that don 't work. Please inform me if you find such an error and I'll try to fix it.

Kind regards

Important read this :

The code on this page is only working when you use Outlook as your mail program.
Copy the code in a Standard module of your workbook, if you just started with VBA see this page.
Where do I paste the code that I find on the internet

Check out this Tip page for changing the code on this page.
Tips for changing the code examples

 

Run macro when you manual change a cell

To run a macro automatic when you manual change a specific cell you can use the Change event in a worksheet module.The example on this page use Cell A1 and will run the macro if the cell value >200.

1) Right click on a sheet tab and choose view code
2) Paste the event below in the sheet module.
3) Alt-q to go back to Excel

Note: Change YourMacroName to the name of your macro in the code.
If you want the code to work for another cell or more cells you can change the range in the event.

Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Cells.Count > 1 Then Exit Sub
    If Not Application.Intersect(Range("A1"), Target) Is Nothing Then
        If IsNumeric(Target.Value) And Target.Value > 200 Then
            Call YourMacroName
        End If
    End If
End Sub

Example mail macro

Test this example macro to create/display a Outlook mail with a small text message.
You must copy this macro in a standard module and not in the worksheet module, see this page how.

Note: I use .Display in the code to display the mail, you can change that to .Send

Do not forget to change Call YourMacroName to Call Mail_small_Text_Outlook in the Change event.

Sub Mail_small_Text_Outlook()
'For Tips see: https://jkp-ads.com/rdb/win/winmail/Outlook/tips.htm
'Working in Excel 2000-2016
    Dim OutApp As Object
    Dim OutMail As Object
    Dim strbody As String

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    strbody = "Hi there" & vbNewLine & vbNewLine & _
              "Cell A1 is changed" & vbNewLine & _
              "This is line 2" & vbNewLine & _
              "This is line 3" & vbNewLine & _
              "This is line 4"

    On Error Resume Next
    With OutMail
        .To = "ron@debruin.nl"
        .CC = ""
        .BCC = ""
        .Subject = "This is the Subject line"
        .Body = strbody
        'You can add a file like this
        '.Attachments.Add ("C:\test.txt")
        .Display   'or use .Send
    End With
    On Error GoTo 0

    Set OutMail = Nothing
    Set OutApp = Nothing
End Sub
 

Run a macro automatic when a specific formula cell reaches a certain value

This is not so easy and can be tricky. You can download a example workbook here with
two examples that both use the Worksheet_Calculate event :

1: check the value of one formula cell
2: check the value of more then one formula cell

In the examples we create a Outlook mail if the value of the formula(s) >200

Early Binding

If you want to use the Intellisense help showing you the properties and methods of the objects as you type you can use Early Binding. Bit faster also when you run your code but you can have problems when you distribute your workbooks. Excel will automatic update the reference number to Outlook when you open your workbook in a higher version of Excel/Outlook but not update it when you open it in a lower version of Excel/Outlook. With Late Binding as I used in the macro examples you not have this problem.

Add a reference to the Microsoft Outlook Library in Excel

1) Go to the VBA editor with the shortcut Alt - F11
2) Click on Tools>References in the Menu bar
3) Place a Checkmark before Microsoft Outlook ? Object Library
    Where ? is the Outlook version number

Then replace this three lines in the code

Dim OutApp As Object
Dim OutMail As Object

Set OutMail = OutApp.CreateItem(0)


With this three lines

Dim OutApp As Outlook.Application
Dim OutMail As Outlook.MailItem

Set OutMail = OutApp.CreateItem(olMailItem)
