How to send email using VB.NET code

By: Issac  

Surprised, we can use SMTP protocol and .net source code for sending an email, SMTP stands for Simple Mail Transfer Protocol, in VB.NET we can use System.Net.Mail namespace for send mail. We can instantiate SmtpClient class and assign the Host and Port. The default port using SMTP is 25, but it may vary different Mail Servers. The following example shows how to send emails from a Gmail address.

The Gmail SMTP server name is and the port using send mail is 587. Here using NetworkCredential for password based authentication.

Imports System.Net.Mail
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click
            Dim SmtpServer As New SmtpClient()
            Dim mail As New MailMessage()
            SmtpServer.Credentials = New _
		Net.NetworkCredential("[email protected]", "password")
            SmtpServer.Port = 587
            SmtpServer.Host = ""
            mail = New MailMessage()
            mail.From = New MailAddress("[email protected]")
            mail.Subject = "Test Mail"
            mail.Body = "This is for testing SMTP mail from GMAIL"
            MsgBox("mail send")
        Catch ex As Exception
        End Try
    End Sub
End Class

You have to provide the informations like your gmail username and password , and the to address also.
