自动发送多封邮件

这个脚本可以帮助我们批量定时发送邮件，邮件内容、附件也可以自定义调整，非常的实用。

相比较邮件客户端，Python脚本的优点在于可以智能、批量、高定制化地部署邮件服务。

需要的第三方库：

Email - 用于管理电子邮件消息

Smtlib - 向SMTP服务器发送电子邮件，它定义了一个 SMTP 客户端会话对象，该对象可将邮件发送到互联网上任何带有 SMTP 或 ESMTP 监听程序的计算机

Pandas - 用于数据分析清洗地工具

import smtplib 
from email.message import EmailMessage
import pandas as pd

def send_email(remail, rsubject, rcontent):
    email = EmailMessage()                          ## Creating a object for EmailMessage
    email['from'] = 'The Pythoneer Here'            ## Person who is sending
    email['to'] = remail                            ## Whom we are sending
    email['subject'] = rsubject                     ## Subject of email
    email.set_content(rcontent)                     ## content of email
    with smtplib.SMTP(host='smtp.gmail.com',port=587)as smtp:     
        smtp.ehlo()                                 ## server object
        smtp.starttls()                             ## used to send data between server and client
        smtp.login("deltadelta371@gmail.com","delta@371") ## login id and password of gmail
        smtp.send_message(email)                    ## Sending email
        print("email send to ",remail)              ## Printing success message

if __name__ == '__main__':
    df = pd.read_excel('list.xlsx')
    length = len(df)+1

    for index, item in df.iterrows():
        email = item[0]
        subject = item[1]
        content = item[2]

        send_email(email,subject,content)
