In this article I will explain with an example, how to send emails with CC and BCC using MailKit using C# and VB.Net.
 
 

Installing MailKit package

You will need to install the MailKit package, for details on installation please refer Install MailKit from Nuget in Visual Studio.
 
 

Sending emails with CC and BCC using MailKit

In order to send emails with CC and BCC, a MimeMessage class object is created.
Then, required properties are set as below:
From – Sender’s email address.
To – Recipient(s) Email Address.
CC – Carbon Copies.
BCC – Blind Carbon Copies.
Note: In case you need complete reference, please refer Send Email using MailKit using C# and VB.Net.
 
C#
using (MimeMessage mm = new MimeMessage())
{
    //Sender email.
    mm.From.Add(new MailboxAddress("Sender", "sender@aspsnippets.com"));
 
    //Recepient Email.
    mm.To.Add(new MailboxAddress("Recepient", "recepient@aspsnippets.com"));
 
    //CC Email.
    mm.Cc.Add(new MailboxAddress("Cc", "cc@aspsnippets.com"));
 
    //BCC Email.
    mm.Bcc.Add(new MailboxAddress("Bcc", "bcc@aspsnippets.com"));
}
 
VB.Net
Using mm As MimeMessage = New MimeMessage()
    'Sender email.
    mm.From.Add(New MailboxAddress("Sender", "sender@aspsnippets.com"))
 
   'Recepient Email.
    mm.[To].Add(New MailboxAddress("Recepient", "recepient@aspsnippets.com"))
 
   'CC Email.
    mm.Cc.Add(New MailboxAddress("Cc", "cc@aspsnippets.com"))
 
   'BCC Email.
    mm.Bcc.Add(New MailboxAddress("Bcc", "bcc@aspsnippets.com"))
End Using
