How to send bulk email in asp.net

9:46 AMFriday, July 4, 2014
If you want to send email in bulk then you should go for my algorithm. I have already learn about SMTP services (how to to send e-mail). Today we will learn , how to send email in bulk. There are various steps to send email in bulk, these are
1. Bind proper information of customer in gridview (learn how to bind gridview in asp.net)


2. Make user friendly application, in which you can insert data in gridview at runtime.(How to insert data into database)
3. Take two textboxes on design window for email-subject and email-message.
4. Also add single button control for sending message.
5. Raise click_event for button control.
6. Run foreach loop for all rows of gridview like

foreach (GridViewRow  gdata in GridView1 .Rows)
        {
}
7. Extract e-mail field from gridview, now, your code look like.

 string email = gdata.Cells[3].Text.Trim();

8. After retrieving single address from gridview, now you can send message.

9. Run your application.

        cmd.Connection =con;
        SqlDataAdapter da=new SqlDataAdapter (cmd);
        DataSet ds=new DataSet();
        da.Fill (ds);
        GridView1.DataSource = ds;
        GridView1.DataBind();

            MailMessage msg = new MailMessage();
            msg.From = new MailAddress("your gmail id here");
            msg.To.Add(email);
            msg.Subject = TextBox1.Text;
            msg.Body = TextBox2.Text;
            msg.IsBodyHtml = true;
            SmtpClient smt = new SmtpClient("smtp.gmail.com", 587);
            smt.EnableSsl = true;
            smt.Credentials = new System.Net.NetworkCredential("your gmail id here", "your gmail password");
