I work in MEP and our emails are always considered legal documents as they can be used as evidence if ever we are taken to court. So we always treat them very technical and try to over explain everything so clients/plan reviewers/contractors can’t misinterpret. It’s kind of an old school thing, but the head of our department is an old school guy.
I used to pre-mix peanut butter and a sick of butter in my kitchen aid and leave it in the fridge for this exact reason.
Sometimes I’d also add Sriracha
