Python production example of sending emails

This article mainly introduces the function of sending emails in python in detail. The modules used are smtplib and MIMEText, which have certain reference value. Interested friends can refer to it

The examples in this article are We have shared the specific code for Python to implement the function of sending emails for your reference. The specific content is as follows

Dependencies:

The Python code implements the function of sending emails, and the module used is smtplib , MIMEText, you need to import the package before implementing the code:

import smtplib
from email.mime.text import MIMEText

Use 163 email to send emails. The specific code implementation is as follows:

import smtplib
from email.mime.text import MIMEText
'''
发送邮件函数，默认使用163smtp
:param mail_host: 邮箱服务器，16邮箱host: smtp.163.com
:param port: 端口号,163邮箱的默认端口是 25
:param username: 邮箱账号 xx@163.com
:param passwd: 邮箱密码(不是邮箱的登录密码，是邮箱的授权码)
:param recv: 邮箱接收人地址，多个账号以逗号隔开
:param title: 邮件标题
:param content: 邮件内容
:return:
'''

def send_mail(username, passwd, recv, title, content, mail_host='smtp.163.com', port=25):
  msg = MIMEText(content)  # 邮件内容
  msg['Subject'] = title   # 邮件主题
  msg['From'] = username   # 发送者账号
  msg['To'] = recv      # 接收者账号列表
  smtp = smtplib.SMTP(mail_host, port=port)   # 连接邮箱，传入邮箱地址，和端口号，smtp的端口号是25
  smtp.login(username, passwd)          # 登录发送者的邮箱账号，密码
  # 参数分别是 发送者，接收者，第三个是把上面的发送邮件的 内容变成字符串
  smtp.sendmail(username, recv, msg.as_string())
  smtp.quit() # 发送完毕后退出smtp
  print('email send success.')

if __name__ == '__main__':
  email_user = 'xxxx@163.com' # 发送者账号
  email_pwd = 'xxxxx' # 发送者密码,授权码
  maillist = 'xxxx@qq.com'
  title = '测试邮件标题'
  content = '这里是邮件内容'
  send_mail(email_user, email_pwd, maillist, title, content)

The method to obtain the authorization code for 163 mailbox is as follows:

1. Log in to 163 mailbox, click Settings-POP3/SMTP/IMAP, as follows:

2. Enable the SMTP service and query the SMTP host address:

3. Click the client authorization password to reset the authorization code:

Use QQ Mail to send emails. The specific code is as follows:

import smtplib
from email.mime.text import MIMEText
'''
发送邮件函数，默认使用163smtp
:param mail_host: 邮箱服务器，qq邮箱host: smtp.qq.com
:param port: 端口号,qq邮箱的默认端口是: 456
:param username: 邮箱账号 xx@163.com
:param passwd: 邮箱密码(不是邮箱的登录密码，是邮箱的授权码)
:param recv: 邮箱接收人地址，多个账号以逗号隔开
:param title: 邮件标题
:param content: 邮件内容
:return:
'''
#qq邮箱发送邮件
def send_mail(username, passwd, recv, title, content, mail_host='smtp.qq.com', port=456):
  msg = MIMEText(content)  # 邮件内容
  msg['Subject'] = title   # 邮件主题
  msg['From'] = username   # 发送者账号
  msg['To'] = recv      # 接收者账号列表
  smtp = smtplib.SMTP_SSL(mail_host, port=port)   # 连接邮箱，传入邮箱地址，和端口号，smtp的端口号是25
  smtp.login(username, passwd)          # 登录发送者的邮箱账号，密码
  # 参数分别是 发送者，接收者，第三个是把上面的发送邮件的 内容变成字符串
  smtp.sendmail(username, recv, msg.as_string())
  smtp.quit() # 发送完毕后退出smtp
  print('email send success.')

if __name__ == '__main__':
  email_user = 'xxx@qq.com' # 发送者账号
  email_pwd = 'WOSHINIGE123' # 发送者密码,授权码
  maillist = 'xxxx@qq.com'
  title = '测试邮件标题'
  content = '这里是邮件内容'
  send_mail(email_user, email_pwd, maillist, title, content)

Multiple recipients with attachments:

# import smtplib
# from email.mime.text import MIMEText
# '''
# 发送邮件函数，默认使用163smtp
# :param mail_host: 邮箱服务器，qq邮箱host: smtp.163.com
# :param port: 端口号,qq邮箱的默认端口是: 25
# :param username: 邮箱账号 xx@163.com
# :param passwd: 邮箱密码(不是邮箱的登录密码，是邮箱的授权码)
# :param recv: 邮箱接收人地址，多个账号以逗号隔开
# :param title: 邮件标题
# :param content: 邮件内容
# :return:
# '''
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

#邮箱服务器地址
email_host = 'smtp.163.com'
#发送者
email_user = 'xxxx@163.com'
#授权码
email_pwd = 'WOSHINIGE123'
#多个收件人，使用分号分隔
maillist ='xxxx@qq.com;aaaa@qq.com'
#对多个收件人进行分割，以；为标准，返回结果是list['xxxx@qq.com','aaaa@qq.com']
email_info = maillist.split(';')
#构造一个发附件的邮件内容对象
new_msg = MIMEMultipart()
#邮件正文内容
new_msg.attach(MIMEText('test email.....'))
#邮件主题
new_msg['Subject'] = 'test email'
#邮件发送者
new_msg['From'] = email_user
#邮件接收者，多个收件人的账号使用，连接，传入类型是str
new_msg['To'] = ','.join(email_info)
#打开a.txt读取文本内容
att = MIMEText(open('a.txt').read())
att["Content-Type"] = 'application/octet-stream'
# 发送附件就得这么写,固定格式，filename指定附件的名字
att["Content-Disposition"] = 'attachment; filename="haha.txt"'
new_msg.attach(att)
# 连接邮箱，传入邮箱地址，和端口号，smtp的端口号是25
smtp = smtplib.SMTP(email_host, port=25)
# 发送者的邮箱账号，密码,先登录
smtp.login(email_user, email_pwd)
smtp.sendmail(email_user, email_info, new_msg.as_string())
smtp.quit()
print('email send success.')

Use semicolon between accounts when there are multiple recipients; split, perform smtp.sendmail (the type of multiple recipients passed in is list); new_msg['TO'] = recv , the receiving type is str

Use the class to send emails, you can send multiple people or send attachments:

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

class SendMail(object):
 def __init__(self, username, passwd, recv, title, content, file=None, email_host='smtp.163.com', port=25):
  self.username = username
  self.passwd = passwd
  self.recv = recv
  self.title = title
  self.content = content
  self.file = file
  self.email_host = email_host
  self.port = port

 def send_mail(self):
  msg = MIMEMultipart()
  #发送内容的对象
  if self.file:#处理附件的
   att = MIMEText(open(self.file, encoding='utf-8').read())
   att["Content-Type"] = 'application/octet-stream'
   att["Content-Disposition"] = 'attachment; filename="%s"'%self.file
   msg.attach(att)
  msg.attach(MIMEText(self.content))#邮件正文的内容
  msg['Subject'] = self.title # 邮件主题
  msg['From'] = self.username # 发送者账号
  #将多个账号'aaa.@qq.com;bbbb@163.com' 以分号分割，分割为list
  self.recv = self.recv.split(';')
  if isinstance(self.recv, list):
   msg['To'] = ','.join(self.recv)
  else:
   msg['To'] = self.recv # 接收者账号列表
  if self.username.endswith('qq.com'): #如果发送者是qq邮箱
   self.smtp = smtplib.SMTP_SSL(self.email_host, port=self.port)
  else:
   self.smtp = smtplib.SMTP(self.email_host, port=self.port)
  #发送邮件服务器的对象
  self.smtp.login(self.username, self.passwd)
  try:
   self.smtp.sendmail(self.username, self.recv, msg.as_string())
  except Exception as e:
   print('出错了。。', e)
  else:
   print('发送成功！')
  self.smtp.quit()

if __name__ == '__main__':
 m = SendMail(
  username='zzzzz@163.com', passwd='xxxxxxx',file='a.txt', recv='xxxxxx@qq.com;xxxxxx@qq.com',
  title='多个收件人', content='哈哈哈啊哈哈哈哈', email_host='smtp.163.com', port=25
 )
 m.send_ma
