I don't know the clear instructions but you can take a snapshot of the specific time in the ETH blockchain and later filter the active ETH addresses with a positive balance for making a list of airdrop receivers. Btw, check this

This is great. Thanks for sharing. I was always curious to know how to airdrop ERC-20 tokens to given ETH addresses on the blockchain. The methods from the article look easy enough to get started with this. I'm going to test it on ETH's testnet just to be safe. An automated approach to sending free tokens to ETH addresses which meet certain requirements could prove to be beneficial for the issuer. I believe that dividends can be sent easily on the ETH blockchain using the given methods above. If it works for ETH, then I guess that it'll work for any other ETH-based fork like ETC and EXP. The only problem will be gas costs (fee), when paying ETH addresses manually across the network. If there was a way to "pre-load" a smart contract with gas, it'll be possible to send automated payments to addresses which proves to save time and cost-effective.
I would say this will surely be a cumbersome task since there are growing Ethereum holders and this would never. Having a database with eth holders like btcltcdigger said would end up difficult to manage as well. You should probably dig the whole Ethereum Blockchain with list of Ethereum holders >1 and try to segregate them. From the list being pulled from Blockchain, you can create a database and can issue a smart contract to perform further tasks.
I have created a token in test network and have airdropped it to a few Ethereum accounts which I had. You can check this link :
https://ethereum.stackexchange.com/questions/25074/how-to-do-an-air-drop-to-all-eth-token-holdersThanks, mate. This is real useful. I think that I have all I need to send "airdropped" tokens to ETH addresses which meet certain requirements. Sending tokens one-by-one can be time-consuming and cost-ineffective if there are many ETH addresses on the blockchain that qualify for the airdrop. Bulk transactions will be ideal for this task, automated by a smart contract on the ETH platform.
Now that I have some articles across the web on how to do a token airdrop to ETH addresses on the blockchain, I'm going to play with ETH's Ropsten Testnet for a while. There are so many things you can do on Ethereum, that's not possible with Bitcoin nowadays. I've learned something new today thanks to you guys.
