SMTPServer Multiple Mail Message Performance

[SirPyros]

I am creating a mass mailer web app. I was wondering if there was a big
performance difference between adding all of the email addresses to the
mailmessage Bcc property or simply sending a new mail message for each
recipient.

The reason I ask if because I want to be able to add a link with the
Recipient ID as a query string parameter for people to unsubscribe from
the list.

Only way I see of doing this is to send each email separately.

Thanks in advance for any help with this.

Or create a page where they can enter their email address to be removed...
