Ballots weren't mailed to the address of every registered voter.
According to the AJC, August 25, 2020:
"Secretary of State Brad Raffensperger sent mailed absentee ballot applications to 6.9 million active voters ahead of the June primary election, helping them vote from home during the coronavirus pandemic.
But for this fall’s general election, Raffensperger replaced that mailing program with a website where voters will soon be able to request absentee ballots.
The website is scheduled to launch within days, and then voters who sign up to receive absentee ballots will be mailed to them starting Sept. 20."
So the only thing that was mailed to voters was an absentee-ballot APPLICATION, not an actual ballot. And the mailout was for the PRIMARY election, not the general.
