What makes these work

Internal-comm subjects benefit from clarity over cleverness. 'Update: payroll provider switch' beats 'Exciting news!' for anything operationally important. Naming the audience ('Engineering team only', 'Managers') in the subject helps recipients prioritize. For all-hands or announcement-style sends, lead with the topic, not the framing ('Q4 review meeting — Thursday' beats 'Important meeting coming up'). Avoid vague subjects that require opening to triage; in a work inbox, opening costs more than skimming.
