You can add previously removed contacts to that same campaign from which they were removed in the first place.
 
They were not removed completely. In other words, they are part of the statistics. 

They are still in the campaign, but their status is changed. This means that they won't receive any further messages unless you change their status to active and re-add them to campaign.
From the single campaign's page, you will have the recipients overview with detailed information on each recipient inside your campaign and their progress within the campaign cycle.
From the Recipient list select the desired one/s and in the Set Status dropdown select Active.
This action returns the contact back into the sequence, and sending to it should continue per schedule from the last sent phase (PHASE column in the recipient list).
