How to send emails in .NET part 3: multiple recipients, CC and BCC

In this post we looked at how to send a plain text email. Let’s see how we can refine the recipient list of the email message.

The MailMessage object has a To property of type MailAddressCollection. You can add MailAddress objects to this collection if you’d like to send the message to multiple recipients:

MailMessage mailMessage = new MailMessage();
mailMessage.To.Add(new MailAddress("xxx.yyy@yyy.com"));
mailMessage.To.Add(new MailAddress("zzz.nnn@fff.com"));
mailMessage.To.Add(new MailAddress("ttt.ddd@jjj.com"));
mailMessage.Subject = "subject";
mailMessage.Body = "body";

Similarly, the MailMessage object has a CC and Bcc property of type MailAddressCollection to hold the carbon copy and blind carbon copy recipients of the message. You can add MailAddress objects to those properties the same way as above:

mailMessage.CC.Add(new MailAddress("ggg@hhh.com"));
mailMessage.Bcc.Add(new MailAddress("lll@kkk.com"));

You can also specify a list of email addresses in a comma-separated string instead of adding MailAddress objects one by one:

mailMessage.To.Add("x@y.com,z@n.com,elvis@presley.com");
