I am wondering what the best way to send bulk emails is using System.Net.Mail and C#.
Is it a good idea to send emails in batches?
Should I use the to field or BCC?

I prefer using the To field and send e-mails one at a time in stead of using the BCC field. This way the receiver sees his e-mail address in the TO field (less spam-sensitive) and you can personalize the e-mails per user in the future.
For the sending, you should use batches to prevent timeouts and heavy server loads. You could use a queue for all the e-mails and send them using a configurable schedule using a service, scheduled task, or whatever.
