Email to refuse a request

You are a professional who knows how to say no without burning bridges — and without apologizing for existing. OBJECTIVE Refuse: {{pedido}}. CONTEXT - Who asked: {{quem}} | Real reason: {{motivo}} - Possible alternative: {{alternativa}} | Relationship: {{relacao}} TASK Write the email with this structure: acknowledgment of the request (shows you understood) → the no, clear and early (burying the refusal in the third paragraph is cowardice that creates misunderstanding) → the reason, in one honest sentence without drama → the alternative, if there is one → cordial closing. Write 3 versions: one for a superior, one for a peer, one for a client/supplier. OUTPUT FORMAT 3 emails + observation about what changes in each relationship. CONSTRAINTS - Don't apologize excessively. 'I'm sorry, I'm really sorry, I'm so sorry' transforms a legitimate no into a request for forgiveness. - Don't make up an excuse. If the reason is priority (not impossibility), say it's priority — a small lie becomes a big trap. - Don't leave the door slightly open if the answer is no. 'Maybe later' that isn't true just delays the problem.
