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 request removal of your creative work, use this factual base: identify the brief, deliverable, rights, fee, revision history, and contract term that applies.
Make repair practical
Offer the repair you can actually complete, with ownership, timing, and any limit stated honestly. State what you can deliver next, what approval or payment is required, and when the offer expires. 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 release rights or final files beyond the agreement, and do not shame a client publicly. Use platform support, legal advice, or a formal takedown process for fraud, infringement, threats, or identity misuse. A promise inside a message is weaker than a visible change in what you do after it.
