Send multiple emails

[shapper]

Hello,

I need to send an email to multiple addresses (I expect no more than
2000).

This will be to send a newsletter. What is the best way to do this?
Use a loop and send 2000 emails?
Send maybe 20 emails with 200 people on the BCC for each?
....

Usually I send one email as follows:


MailMessage mail = new MailMessage();

mail.Body = body;
mail.From = from;
mail.IsBodyHtml = false;
mail.Priority = MailPriority.Normal;
mail.Subject = subject;
mail.To.Add(...);

try {

SmtpClient smtp = new SmtpClient();
smtp.Send(mail);

} catch {
// Do something
}

Thank You,
Miguel

If we assume that you mean fastest, then my suggestion will be:
- small number of threads
- sending to a medium size number of users (many mail servers
will reject 2000 recipients)
- always BCC to protect the recipients privacy
