<< Return to Send Email Tutorial Page
 

Note:
In the below code when we are creating an email in Outlook then at the end of the email, we will insert the Signature from the .txt file or .htm file.

Signature

In the below code we are first checking if these files exists and have some values in it. If yes then we are reading the text from the signature file and inserting that signature in the email.
Thus we need a function which read and return the Signature Texts from the file wherever we need to insert it in the body of the Outlook email.

Function to read the Signature file and return the Signature Text

Function GetSignature(fPath As String) As String
    Dim fso As Object
    Dim TSet As Object
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set TSet = fso.GetFile(fPath).OpenAsTextStream(1, -2)
    GetSignature= TSet.readall
    TSet.Close
End Function

Below is the code to create the Outlook Email with the Signature at the end.
Here there could be two types of Email and Signatures:

We will see the code of both the above methods below one by one:

Email and Signature with Simple Text

Sub With_Text_Signature()

    'Do not forget to change the email ID
    'before running this code

    Dim OlApp As Object
    Dim NewMail As Object
    Dim EmailBody As String
    Dim StrSignature As String
    Dim sPath As String

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

    EmailBody = "Type the Body of your email"

    ' go to the appdata path as mentioned in
    ' the above important point. Check the name of
    ' the signature file. For example: here in my system
    ' the signature's file name is vish.txt, vish.htm
    ' Therefore before running this code, check the
    ' name fo the signature file in your system and
    ' replace vish.txt with your file name.
    '****************************************************

    sPath = Environ("appdata") & "\Microsoft\Signatures\vish.txt"

    ' If the path and file name given by you is not
    ' correct then code you insert a blank Signature
    
    If Dir(sPath) <> "" Then
        StrSignature = GetSignature(sPath)
    Else
        StrSignature = ""
    End If

    On Error Resume Next
    With NewMail
        .To = "info@learnexcelmacro.com"
        .CC = "info@learnexcelmacro.com"

        .Subject = "Type your Subject here"
        ' Here at the end of the Email Body
        ' Text Signature is inserted.
        .Body = EmailBody & vbNewLine & vbNewLine & StrSignature
        .send
    End With
    On Error GoTo 0
    Set NeMail = Nothing
    Set OlApp = Nothing
End Sub

Email and Signature with HTML Body and HTML Signature

Sub With_HTML_Signature()

    'Do not forget to change the email ID
    'before running this code

    Dim OlApp As Object
    Dim NewMail As Object
    Dim EmailBody As String
    Dim StrSignature As String
    Dim sPath As String

    Set OlApp = CreateObject("Outlook.Application")
    Set NewMail = OlApp.CreateItem(0)
    
    ' Here Since we are talking about
    ' the HTML email then we need to
    ' write the Body of the Email in
    ' HTML.

    EmailBody = "Hello Friends !!" & "

Welcome to LearnExcelMacro.com" & vbNewLine & _
    "Here i will make you awesome in Excel Macro.
