That is not entirely true. Sometimes you already have the person authenticated via another fashion (think: online banking software), and all that you want to do is have the user subscribe for banking notices by pressing one button.

Well in any event, you should confirm the subscription; otherwise anyone can subscribe anyone else to your list.
This is known as confirmed opt-in, and if you don't use a system like this, you're very likely to get booted by your ISP for spamming.
