Sounds like you are talking about adding names to a static list, which is also being used in a smart campaign to which you will be blasting out an email.
In the scenario you described above, 110 leads will be on track to receive the email. So the short answer is, yes, any names you add to a static list will then be added to qualify for any smart campaign targeting that list.
One way to confirm this is to just go to the Schedule tab on your smart campaign and see how many names will pop up in the "Set to Affect" line after you've added new names to your static list. The Schedule tab should reflect all new names as soon as they have been uploaded to your list.
