Department for the Mitigation of Spam Email Cascades

[magistrate]

AO3-savvy friends, help me out here. Suppose that I have a long multi-chapter work which I would like to blame on gift to another user. If I set it up as a gifted work when I started posting, would they be hit with a notification email every time I posted a new chapter? If I didn't want someone to be pestered every week (or whatever) for •mumble• weeks, would it be wiser to just post the thing through and then gift it at the end?

Any insight is appreciated. I have really not been posting enough on AO3 recently to know the ins and outs of these things.
