Name the impact without exaggerating it
Describe who had to wait, worry, redo work, spend money, or make a choice with incomplete information. For a message about how to follow up on a promotion request, use this factual base: restate the role, conversation, submission, or promise and include the relevant date or reference.
Make repair practical
Offer the repair you can actually complete, with ownership, timing, and any limit stated honestly. Ask one answerable question, make any real deadline visible, and offer an easy way to close the loop. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Let future behavior carry the proof
Do not send daily reminders, manufacture competing offers, or contact unrelated employees for leverage. Use the official application or accessibility channel when the matter involves protected information or accommodation. A promise inside a message is weaker than a visible change in what you do after it.
