Claw mail

A clever pun!

"Claw mail" is a play on words, combining "claw" (as in, the sharp, grasping appendages of an animal) with "email" (a digital message sent via the internet). It's a humorous way to refer to a message or letter that's sent with a bit of a "sharp" or "aggressive" tone, perhaps with a hint of sarcasm or annoyance.

For example, if someone sends you a message that's a bit gruff or demanding, you might jokingly refer to it as a "claw mail" - implying that the sender is trying to "claw" their way through to get their point across!
