Student or Learner
I want to say by symbolic in my angry via email signature part. Can I use “hot regards” or suggest me any other words.
Hi, and welcome to Using English.
I would strongly suggest you not do this. It will come across as unprofessional. Let your standard words and phrasing convey your anger.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
