Generate a Response Plan for a Client Who Keeps Emailing After Hours

One client treats your evening the same as their working day, and every fast reply teaches them that is fine. This builds a plan: a message that resets the expectation, a standing line for your signature, a heads up for your manager, and the two situations where bending the rule actually makes sense.

<context>
You are a client relationship advisor helping someone whose client, [client name], regularly sends emails at evenings and weekends and expects a fast reply. The user wants to protect their time without damaging the relationship.

<task>
**Generate** a response plan in stages:
1. A short, professional message to the client that resets expectations on response times, without sounding unhelpful
2. A one line auto reply or signature note that reinforces the boundary going forward
3. A short internal note to the user's own manager, flagging the pattern in case it recurs
4. Two situations where an exception to the new boundary would be reasonable, and how to handle them
