在Python中使用循环向多个收件人发送自定义电子邮件

import smtplib
from email.mime.text import MIMEText
from email.header import Header

# 邮件服务器配置
smtp_server = 'smtp.example.com'
smtp_port = 25
smtp_username = 'your_username'
smtp_password = 'your_password'

# 收件人列表
recipients = ['recipient1@example.com', 'recipient2@example.com', 'recipient3@example.com']

# 邮件内容
subject = '自定义邮件主题'
content = '自定义邮件内容'

for recipient in recipients:
    # 创建邮件对象
    message = MIMEText(content, 'plain', 'utf-8')
    message['From'] = Header('发件人', 'utf-8')
    message['To'] = Header(recipient, 'utf-8')
    message['Subject'] = Header(subject, 'utf-8')

    try:
        # 连接邮件服务器
        server = smtplib.SMTP(smtp_server, smtp_port)
        server.login(smtp_username, smtp_password)

        # 发送邮件
        server.sendmail(smtp_username, recipient, message.as_string())
        print(f'邮件发送成功给 {recipient}')
    except Exception as e:
        print(f'邮件发送失败给 {recipient}，错误信息：{str(e)}')
    finally:
        # 关闭连接
        server.quit()
