"However, the reason why phishing emails have so many typos is simple—they’re intentional and are included by design. The scammer’s goal is to send phishing emails to a very gullible, innocent victim. If they have typos, they’re essentially weeding out recipients too smart to fall for the scam."
The logic of that defeats me.
And whatever logic it has is subverted by the comment in the next paragraph:
"Sometimes, the sender might not speak the language they’re writing in, which explains typos, grammatical errors and strange phrases or sentences."
