I am using the SmtpClient in C# and I will be sending to potentially 1000s of email addresses. I want to only the recipient's email address is displayed. for example:

I send email to aa@xx.xx,bb@xx.xx,cc@xx.xx,dd@xx.xx... aa can only see the email address aa@xx.xx,bb can only see the email address bb@xx.xx. they don't know I send the email to others.

Use mail.BCC instead of mail.To for users who's addresses you dont't want to display to others

  • "I want to only the recipient's email address is displayed" How would you display the users address if it is in the BCC? – Onots Dec 18 '14 at 07:23
