send to new (missed) subscribers only

What's the best method for this:
  • Campaign goes out to list.
  • next day a new bunch of subscribers are being added.
  • How do we send the campaign to just those new subscribers?
There is an "opened/clicked XYZ Campaign" segmentation option (although we all know how inaccurate that is). But there's no "received/sent XYZ Campaign" - and more importantly, there's no negative option: NOT opened/clicked/received/sent. Is that difficult to add?

Even better, rather than making that a segment, can that not be part of the campaign setup options?
