How set gmil mails automate with vba
A very specific and interesting question!
To automate sending GMails using VBA, you'll need to use the MSXML2.XMLHTTP
object to send an HTTP request to the Gmail SMTP server. Here's a step-by-step guide to help you achieve this:
Prerequisites:
- You have a Gmail account with 2-Step Verification (2SV) disabled.
- You have the
MSXML2.XMLHTTP
object installed on your system (it's usually included with Office installations). - You have a VBA project set up in your Excel workbook.
Step 1: Set up your Gmail account
- Go to your Gmail account settings and enable "Less secure app access" (this is required for VBA automation).
- Note down your Gmail username and password.
Step 2: Create a VBA function to send an email
Create a new module in your VBA project and add the following code:
Sub SendGmail()
Dim xmlHttp As Object
Set xmlHttp = CreateObject("MSXML2.XMLHTTP")
' Set your Gmail credentials
Dim username As String: username = "[email protected]"
Dim password As String: password = "your_password"
' Set the email details
Dim toAddress As String: toAddress = "[email protected]"
Dim subject As String: subject = "Test Email from VBA"
Dim body As String: body = "This is a test email sent from VBA."
' Set the SMTP server and port
Dim smtpServer As String: smtpServer = "smtp.gmail.com"
Dim smtpPort As Integer: smtpPort = 587
' Set the authentication headers
xmlHttp.Open "POST", "https://" & smtpServer & ":" & smtpPort & "/smtp", False
xmlHttp.setRequestHeader "Authorization", "Basic " & EncodeBase64(username & ":" & password)
xmlHttp.setRequestHeader "Content-Type", "text/plain"
' Set the email body
xmlHttp.send body
' Check if the email was sent successfully
If xmlHttp.Status = 250 Then
MsgBox "Email sent successfully!"
Else
MsgBox "Error sending email: " & xmlHttp.Status
End If
Set xmlHttp = Nothing
End Sub
' Helper function to encode the username and password
Function EncodeBase64(str As String) As String
Dim bytes() As Byte
bytes = StrConv(str, vbFromUnicode)
EncodeBase64 = ConvertToBase64(bytes)
End Function
' Helper function to convert bytes to Base64
Function ConvertToBase64(bytes() As Byte) As String
Dim base64 As String
Dim i As Integer
For i = 0 To UBound(bytes)
base64 = base64 & Chr$(bytes(i) / 64) & Chr$(bytes(i) Mod 64)
Next i
ConvertToBase64 = base64
End Function
Step 3: Call the VBA function
To send an email, simply call the SendGmail
function from your VBA code. For example:
Sub TestEmail()
SendGmail
End Sub
Note: This code uses the MSXML2.XMLHTTP
object to send an HTTP request to the Gmail SMTP server. This is a simple and straightforward approach, but it may not be as secure as using a dedicated email library or API.
Security considerations:
- Make sure to store your Gmail credentials securely, as they will be stored in plain text in your VBA code.
- Be aware that using VBA to automate email sending may be against Gmail's terms of service.
- Consider using a more secure approach, such as using OAuth 2.0 or a dedicated email library, to authenticate with Gmail.
