In order to create an Airdrop for your collection, you will first have to have created an Edition.
When you are looking at the main page for your Edition
Click “Manage collection”
Follow through to the top tab that says “Airdrop"
From here, add the ENS names and/or wallet addresses of the users you would like to add to your Airdrop list.
Once you have added all the addresses you would like in your Airdrop, click “Airdrop # NFTs”.
Approve the Gas fee: A message will appear within your connected wallet for you to approve the gas fee to complete the Airdrop of your edition. Gas fees are the cost of interacting with the Ethereum blockchain. Gas fees are not set or collected by ZORA.
Wait for your transaction to complete: Once you’ve approved the transaction within your wallet, the Airdrop process has begun. You are able to check the status of your upload by clicking the "View on Etherscan" link in your connected wallet
After your transaction and your airdrop has been successful, you will see a green “sent” message
