For hackers, it's a numbers game. An estimated 3.4 billion phishing emails are sent every day, but all they need is for one of them to find a willing victim and do damage to your network.
And in 2026, the odds have shifted further in the attacker's favor. Generative AI now writes the majority of phishing emails, producing fluent, personalized, typo-free messages that are far harder to spot than the clumsy scams of a few years ago. Research shows AI-crafted phishing lures achieve dramatically higher click rates than traditional ones, while costing attackers almost nothing to produce at scale.
Needless to say, leaving email security up to end users is probably not a good idea.
