How to Send Email Using VB.Net

Sending and receiving emails has now become an important task in our daily life. Email service providers such as Hotmail, Gmail & Yahoo have provided their SMTP Ports so that third party developers can use them in their applications.

In visual basic.net we use SMTP i.e Simple Mail Transfer Protocol which helps us in composing electronic mails and sending them to various sources.

We need to import the following namespace “Imports System.Net.Mail” in order to use the SMTP class.

About System.Net.Mail Namespace

This Namespace provides various list of classes that help us to create, send, receive and do many other email related tasks.

How to Send Email Using VB.Net

I’ll demonstrate a simple example that allows us to send emails in vb.net:

1. Create a new windows form application project in visual basic.net.

2. Add three labels and three textboxes and name them as given below:

Label1  –  To
Label2  –  Subject
Label3  –  Body

3. Add a button and change its text to Send.

 
4. Double click button to switch to code view and paste the code given below.

Dim MyMailMessage As New MailMessage()
        Try
        MyMailMessage.From = New MailAddress("youremail")
        MyMailMessage.To.Add(TextBox1.Text)
        MyMailMessage.Subject = TextBox2.Text
        MyMailMessage.Body = TextBox3.Text
        Dim SMTP As New SmtpClient("smtp.gmail.com")
        SMTP.Port = 587
        SMTP.EnableSsl = True
        SMTP.Credentials = New System.Net.NetworkCredential("youremail", "yourpassword")
        SMTP.Send(MyMailMessage)
        MsgBox("Your Mail has been Successfully sent")
        TextBox1.Clear()
        TextBox2.Clear()
        TextBox3.Clear()
        TextBox1.Focus()
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try

5. Change youremail with your current email address and yourpassword with your email ID’s password. Don’t forget to import the following namespace: Imports System.Net.Mail 

That’s it!! Run your Project and send a test email.

Note: It works only with Gmail Account because we have used Gmail’s SMTP Port.
