I have nothing to add to Mark's answer to question 1.
2- If that email consumes 200GB of my monthly bandwidth, while my monthly bandwidth limit is only 8GB, sending that one email will explode and break down my whole website or it will just give me an error that this number is higher than allowed bandwidth?
This is a question for your hosting provider. We can't answer it.
Strictly speaking, Mark is correct. Being Mark means being always correct, so he can't speculate. :-) I can, however.
Experience reported on the Mailman lists over the past decade shows that there are two common local limits. One is count of recipients. If a single submission exceeds that, the local MTA may refuse to send that message, and you get the error, but don't use any bandwidth. No subscribers get the post. Not good, but usually not a disaster (for the subscribers).
The second common experience is that the MTA limits either count or bandwidth, and stops sending. Then some subscribers get mail and others don't. This is very bad in most cases. However, you get a new allocation next month.
The third case is that the MTA limits *and queues the remainder*. You are now well and truly hosed. You need to get your host to delete the post from the MTA queue, or you won't get a usable allocation for a while.... (Note that AFAIK this case is usually applied by services that have a daily rather than a monthly quota.)
There is a fourth case, Host Provider sends the emails then sends you a bill for the overage at the rate specified in the contract. This could be very expensive for going that much over limit.
