代码实现了完整的QQ邮箱批量发送功能，包含异常处理和模板渲染功能。使用时需要先到QQ邮箱设置中开启SMTP服务并获取授权码。如需进一步扩展功能，可以参考代码中的扩展建议进行开发。
QQ邮箱批量群发系统开发指南
一、技术原理
本系统基于SMTP协议实现，核心组件包括：
邮件构造模块(MIME协议)
身证模块(SSL加密)
批量发送控制模块
异常处理机制
二、完整实现代码
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.header import Header
import time
import csv
from typing import List
class QQMailBulkSender:
def init(self,
sender_email: str,
auth_code: str,
smtp_server: str = "smtp.qq.com",
smtp_port: int = 465):
"""
初始化邮件发送器
:param sender_email: 发件人QQ邮箱
:param auth_code: SMTP授权码(非QQ密码)
:param smtp_server: SMTP服务器地址
:param smtp_port: SMTP端口(SSL加密)
"""
self.sender = sender_email
self.auth_code = auth_code
self.smtp_server = smtp_server
self.smtp_port = smtp_port
self.server = None
def connect(self) -> bool:
"""建立SMTP连接"""
try:
self.server = smtplib.SMTP_SSL(self.smtp_server, self.smtp_port)
self.server.login(self.sender, self.auth_code)
return True
except Exception as e:
print(f"连接失败: {str(e)}")
return False
def build_email(self,
receiver: str,
subject: str,
content: str,
content_type: str = "plain") -> MIMEMultipart:
"""构建MIME邮件对象"""
message = MIMEMultipart()
message['From'] = Header(f"发件人<{self.sender}>")
message['To'] = Header(f"收件人<{receiver}>")
message['Subject'] = Header(subject, 'utf-8')
# 添加正文
body = MIMEText(content, content_type, 'utf-8')
message.attach(body)
return message

print(f"发送成功: {receiver}")
return True

return False
def send_bulk_from_csv(self,
csv_path: str,

content_template: str,
delay: float = 1.0) -> dict:
"""
从CSV文件批量发送
:param csv_path: 收件人CSV文件路径

:return: 发送结果统计
"""
results = {"total": 0, "success": 0, "failed": 0}
try:
with open(csv_path, mode='r', encoding='utf-8') as file:
reader = csv.DictReader(file)
for row in reader:
results["total"] += 1
# 渲染模板
rendered_content = content_template.format(**row)
rendered_subject = subject.format(**row)
if self.send_single(row['email'], rendered_subject, rendered_content):
results["success"] += 1
else:
results["failed"] += 1
time.sleep(delay) # 防止发送频率过高
except Exception as e:
print(f"批量发送异常: {str(e)}")
return results
def close(self):
"""关闭连接"""
if self.server:
try:
self.server.quit()
except:
pass
使用示例
if name == "main":
# 配置信息
SENDER_EMAIL = "your_email@qq.com"
AUTH_CODE = "your_smtp_auth_code" # 在QQ邮箱设置中获取
# 创建发送器实例
sender = QQMailBulkSender(SENDER_EMAIL, AUTH_CODE)
# 单封邮件发送示例
sender.send_single(
receiver="target1@example.com",
subject="测试邮件",
content="这是一封测试邮件内容"
)
# 批量发送示例(需准备recipients.csv)
template = """尊敬的{name}：
感谢您使用我们的服务，您的会员账号是：{account}
到期时间：{expire_date}
如有任何问题，请联系客服。
"""
results = sender.send_bulk_from_csv(
csv_path="recipients.csv",
subject="您的账户提醒",
content_template=template,
delay=1.5
)
print(f"批量发送完成，成功：{results['success']} 失败：{results['failed']}")
# 关闭连接
sender.close()
三、CSV文件格式要求
name,email,account,expire_date

李四,lisi@example.com,AC789012,2025-11-30
四、注意事项
必须使用SMTP授权码(非QQ密码)
每日发送上限约500封(根据QQ邮箱规则)
建议发送间隔大于1秒
重要邮件建议添加阅读回执功能
HTML内容需将content_type改为"html"
五、扩展功能建议
添加附件支持
实现邮件追踪功能
加入发送队列管理
开发图形化操作界面
增加发送失败重试机制
