Sending mail to multiple recipient


For sending mail to multiple recipients you can use BCC to send Blind Carbon Copy to each recipient. When you specify recipient in Bcc they will receive message, but the names will not be visible to other recipients.
But instead of using BCC, you should send a separate copy of your message to each recipient that you want to receive blind copy. The problem with BCC is that spam filters frequently block messages that do not have recipient’s email address in the From header. Therefore, if you use BCC, the message will very likely be filtered.
In my previous post I have shown how to send email. Here I would like to rewrite BuildMail() method for sending mail to multiple recipient at a time:
    private MailMessage BuildMail()
    {
        string from, to, bcc, cc, subject, body;
        from = "uniquesaiful@gmail.com";   //Email Address of Sender
        to = "tips.asp.net@gmail.com,saifulondotnet@gmail.com,uniquesaiful@gmail.com";   //Email Address of Receiver
        bcc = "";
        cc = "";
        subject = "This is a test email. I am just checking whether email client is working properly.";
 
        StringBuilder sb = new StringBuilder();
        sb.Append("Hi Scott,<br/>");
        sb.Append("This is a test email. We are testing out email client. Please don't mind.<br/>");
        sb.Append("We are sorry for this unexpected mail to your mail box.<br/>");
        sb.Append("<br/>");
        sb.Append("Thanking you<br/>");
        sb.Append("Tips.Asp.Net");
        
        body =sb.ToString() ;
 
        MailMessage mail = new MailMessage();
        mail.From = new MailAddress(from);
        if (to.Contains(","))
        {
            string[] tos = to.Split(',');
            for (int i = 0; i < tos.Length; i++)
            {
                mail.To.Add(new MailAddress(tos[i]));
            }
        }
        else
        {
            mail.To.Add(new MailAddress(to));
        }
 
        if (!string.IsNullOrEmpty(bcc))
        {
            if (bcc.Contains(","))
            {
                string[] bccs = bcc.Split(',');
                for (int i = 0; i < bccs.Length; i++)
                {
                    mail.Bcc.Add(new MailAddress(bccs[i]));
                }
            }
            else
            {
                mail.Bcc.Add(new MailAddress(bcc));
            }
        }
        if (!string.IsNullOrEmpty(cc))
        {
            if (cc.Contains(","))
            {
                string[] ccs = cc.Split(',');
                for (int i = 0; i < ccs.Length; i++)
                {
                    mail.CC.Add(new MailAddress(ccs[i]));
                }
            }
            else
            {
                mail.CC.Add(new MailAddress(bcc));
            }
            mail.CC.Add(new MailAddress(cc));
        }
 
        mail.Subject = subject;
        mail.Body = body;
        mail.IsBodyHtml = true;
        mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
 
        return mail;
    }

    smtp.Credentials = new System.Net.NetworkCredential
    (TextBox3.Text, TextBox9.Text);//YourUserName@gmail.com,YourGmailPassword
