Gmail uses machine learning to block spam. Approximately how many spam messages does Gmail block daily due to ML?

• A. 10 million
• B. 1 billion
• C. 100 million
• D. 100 thousand

Answer: (C)

Gmail’s spam filtering is powered by machine learning that runs across enormous volumes of email every day. The system learns from vast datasets and real-time signals to catch evolving spam patterns before messages reach users’ inboxes, which means the daily impact is measured in hundreds of millions of blocked messages globally. The figure around 100 million per day reflects that large-scale, real-time protection. Numbers like 10 million would understate Gmail’s reach, while 1 billion is higher than commonly cited public estimates, and 100 thousand is far too small for a global service. So, about 100 million per day is the best approximation.
