Plz.. how to send nearly 700 e-mail at a time in asp.net

[arunmozhi]

hi. i need to send nearly 700 email at a time using asp.net., the email address will be in dataset, using for loop i had taken the email address one by one., but i dont know whether it will send the email without timeout thread or something else.

For testing purpose i can't able to test to send mail upto 700 Address.

Here is my code.

ds = objDb.ActiveMailID();
            for (int i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
            {
                MailMessage message = new MailMessage();
                message.From = "[e-mail]";
                string to = ds.Tables[0].Rows[i]["Email"].ToString();
                message.To = to;
                message.Subject = txttitle.Text.ToString();
                message.BodyFormat = MailFormat.Html;
                message.Body =  PanelToHtml(Panel1);
                message.Priority = MailPriority.Normal;
                SmtpMail.SmtpServer = "mail.domain.com";
                SmtpMail.Send(message);
             }
