If I had signed up, personally I would want an email when you go live (usable beta level). I don't want a confirmation, I don't want to know that you are 37.5% done, I don't want to know what your dog had for breakfast.

When you send me an email that you have gone live, either a link to continue to be on your mailing list or a link to request to be off would be good.

To me "notify" signifies a "one off" email saying "hey, we're live".

I think the "click here to continue to be on the list" is more polite than "click here to unsubscribe" in this case.

What would be better still would be to spell out the situation under the input box. e.g. "We'll only send you one email when we're live" or "We'll spam you everyday until you tell your friends" or something in between. Just be upfront about it so people's expectations are accurate.

I'll make an unsubscribe link pretty prominent, thanks!

Two other things on unsubscribing. One as an spam detector I use a different variation on email address for every site I ever sign up to, so "reply to unsubscribe" sucks (I note that you said a link, which I like).

I have been stupid enough to push a unsubscribe link by mistake. I prefer that it automatically unsubscribes me rather than having to push a button to confirm, but it is not a bad thing to also have a Whoops I made a mistake button.
