Newsletter concernings..

I have been asked if I can build a newsletter-function for somebody.

I have no problem with the functions, so the question isn't about that. My concering is this:

People doesn't like that their email-adresses are spread to everybody. It means that I can't just put the adresses in the recipient's field (To).

I'm thinking about two options:

1. Put all adresses as BCC.
(But I have experienced that if you have many BCC's the mail can fuc. up.)

2. Make a loop that sends one newsletter to the first recipient, then to the next recipient etc.
(Will this make a heavy load on the server? Doesn't wan't the BIG server-owner chasing my butt because I'm making he's server slow.. I have no idea of how many that will register to the newsletter.)

What do you recommend?

I recomend <shamless plug>MailWorks</shamless plug> (URL) however if you want to truely do it right, you will have to do a loop, the only thing is it will time out. So you will need to figure out a way to do it in batches.
