Regarding the return addresses. I don't know how it works in Georgia, but in my state, early voting was done with a mail-in ballot. You check in as you would on election day. You fill out the ballot as you would on election day. Then you enclose the ballot in a blank envelope and put it in the box. You don't fill out return address or any of that because you already verified your identity when you checked in.

However, she says specifically that these are absentees. Also, I would think early-votes would be kept separate because you wouldn't want them mixed in with absentees where voter information still needs to be checked and signatures matched.
