1.先开通邮件的POP3/SMTP/IMAP，拿到授权密码，注意，不是邮箱密码

2.相关代码，里面涉及到的数据库和邮件，都是相对路径下的，可根据代码自行创建和维护

#!pip install PyEmail
    import smtplib # smtp 简单邮件传输协议
    from email.mime.text import MIMEText
    from email.header import Header
    import pandas as pd
    from email.mime.multipart import MIMEMultipart
    
    
    
    
    mail_host = 'smtp.163.com'  # SMTP服务器IP，如果是163，可能是smtp.163.com
    mail_user = 'xxxxx@163.com'  # 用户名
    mail_pass = '******'   # 密码 授权密码，非邮箱密码
    
    sender = 'xxxx@163.com'  # 发件人邮箱与mail_user要一致
    
    
    
    
    
    # 定义发送邮件函数，参数为邮箱联系人分组
    def SendMail(group):
        data = group.reset_index(drop=True)
        receiver = data.loc[0,'邮箱'] #收件人从dataframe取
        Excels = data['公司'].to_list()
        
        #创建一个带附件的邮件实例
        msg = MIMEMultipart()
        msg['From'] = sender
        msg['To'] = receiver
        msg['Subject'] = Header('成本会计一课', 'utf-8')
        
        #邮件正文内容
        msg.attach(MIMEText('hello everybody……', 'plain', 'utf-8'))
        
        # 构造附件
        for file in Excels:
            msg_xlsx = MIMEText(open(r'邮件集合/'+file+'.xlsx', 'rb').read(), 'base64', 'utf-8')
            msg_xlsx.add_header('Content-Disposition', 'attachment', filename=file+'.xlsx') 
            msg.attach(msg_xlsx)
        
        #发送邮件
        try:
            smtpObj = smtplib.SMTP_SSL(mail_host, 465)  #465 是SMTP 端口号
            smtpObj.login(mail_user, mail_pass)  
            smtpObj.sendmail(sender, receiver, msg.as_string())
            print('邮件发送成功：'+receiver)
        except smtplib.SMTPException:
            print('Error: 无法发送邮件receiver：'+receiver)
            
            
            
            
    
    # 使用函数
    df1 = pd.read_excel('公司与邮箱数据.xlsx', sheet_name=0,converters = {'公司': str}) 
    df1.groupby(['邮箱'], as_index=False).apply(SendMail)
