Email is the mainstream channel for Web3 and blockchain projects to reach global Binance investors, but there are multiple fatal problems in batching unscreened email addresses:
Massive invalid emails and no Binance account at all
High bounce rates destroy the reputation of the sending domain name, and the emails go directly into the trash.
Marketing costs are completely wasted, and the production ratio is seriously unbalanced
Manually checking whether the email address is registered with Binance is extremely inefficient
Encrypted email promotion adds high bounce rates, intensifying compliance risks
