That's the only thing they did wrong. Why mention you used ChatGPT? It's like emails that end with "sent from my iPhone" like who cares what technology you used to send an email?
Personally I think it was motivated by trying to create a marketed feeling of exclusivity , drive a stake between Those With and Those Without, and alienate those without into buying an iProduct and joining The Club.
One reason I feel that way is that the only time I'd see it in a work context is if it's a phishing email.
No one really cares where I’m at. I have my laptop signature set to:
Thanks,
Kayodé
$NAME
$RANK
$SERIALNUMBER
I leave it there even if using “Thanks” isn’t entirely correct and my name is repeated below it. Everyone else here does something similar.My phone signature is the iPhone default. Just like everyone else.
I’m grateful the default Mail sig works as a graceful catch-all rather than fitting in an awkward mea culpa in the body or (worse) slapping in some boilerplate sig that might as well read “this email is unreliable and so am I” to certain types of people.
