That e-mail come to me too but i didnt click on there really i am shocked now.Even slackbot can send spam message??thanks for your warning because i will probably click
Yes, this happened to me too in the Waves slack account a month ago, got an email from their slack bot about updating something...in the live discussions on slack they were warning users about the message as a phishing scam. I almost clicked it cause it looked SO legit and you don't really think twice when you think it comes from a trusted source.
So yeah, careful what you click!
