But some of airdrop didn't accept temp email. That why i am using my 2nd email for every airdrop. But i'm regret now. too many spam on my email from scammer that saying i got free token bla bla bla you need to claim and etc. so now i won't do KYC for airdrop. Better just do kyc on bounty that more worth it
It's still worth it if you use gmail. Gmail let you sort out legitimate emails from spam emails. It automatically sorts it and if ever some newsletter arrive at your primary email, you may put them to spam or just block them. I see nothing wrong in using alternative email account for the purpose of bounty and airdrop.
