LLM邮件集成
电子邮件是商业通信的核心工具,每天产生海量邮件数据。大语言模型(LLM)正在彻底改变邮件处理方式,通过自动回复、智能分类、内容生成和深度分析,大幅提升邮件处理效率和质量。
智能邮件分类
LLM能够理解邮件内容和上下文,自动进行多维度分类,远超传统基于规则的分类方法。
import imaplib
import email
from email.header import decode_header
from typing import List, Dict, Any
class IntelligentEmailClassifier:
"""智能邮件分类器"""
def __init__(self, llm_client):
self.llm_client = llm_client
def classify_email(self, subject: str, body: str,
sender: str, recipients: List[str] = None) -> Dict[str, Any]:
"""对单封邮件进行分类"""
prompt = f"""对以下邮件进行多维度分类:
发件人: {sender}
收件人: {', '.join(recipients) if recipients else '未指定'}
主题: {subject}
内容:
{body[:1000]}
请提供以下分类:
1. 邮件类型(工作、营销、通知、个人、垃圾邮件等)
2. 紧急程度(紧急、重要、一般、低优先级)
3. 处理状态(待处理、需回复、仅供参考、已完成)
4. 主题分类(项目、客户、财务、人事、技术等)
5. 情感倾向(积极、中性、消极、紧急)
6. 建议的后续动作
"""

results.append(result)
except Exception as e:
print(f"分类邮件失败: {e}")
results.append({

})
return results
def generate_priority_list(self, emails: List[Dict[str, str]]) -> List[Dict]:

"""
priority_list = self.llm_client.generate(prompt, temperature=0.3)

result = classifier.classify_email(
subject="项目进度报告 - 紧急",
body="请尽快提交本周的项目进度报告,客户要求明天开会讨论。",
sender="manager@company.com",
recipients=["team@company.com"]
)
print(f"分类结果: {result['classification'][:200]}...")
智能邮件分类的关键优势在于理解邮件的上下文和意图,而不仅仅是关键词匹配。它能够识别邮件的紧急程度、处理状态和后续动作,为用户提供有价值的邮件管理建议。
自动回复生成
LLM能够根据邮件内容、发件人关系和历史回复模式,生成个性化、专业的自动回复。
