Paste an email and it gets checked against known passive-aggressive tells — "per my last email," "gentle reminder," "just floating this back to the top of your inbox," and the rest of the genre. Every point on the reading ties to a phrase actually found in the text.
The thermometer runs warm for genuinely direct, low-drama emails and drops toward frozen the more of the genre shows up. Ice doesn't mean angry — it means the anger is being routed through politeness instead of said outright.
