# Set the port number, digital 
EMAIL_PORT = 25 
# set sender's mail 
EMAIL_HOST_USER = '[email protected]' 
# set the sender authorization code 
EMAIL_HOST_PASSWORD = 'own authorization code' 
# whether to enable a secure link 
EMAIL_USER_TLS = True 

# this configuration above information, Django will automatically read, 
# using the account number and authorization code to login 
# If the login is successful, you can send the message 
`` ` 
#### 2, back views.py file, add the following code 
` `` Python 
# introduced means for transmitting the message 
from the django.core.mail the send_mail Import, send_mass_mail, EmailMultiAlternatives 
from Import Settings django.conf 

the send_mail ( 'on holiday notice Mid', 
        'Mid put three days off '
        '[email protected]', 
        [ '[email protected]'] 
        fail_silently = False) 
        # value of 1: 2 message header value: Value message owner 3: Sender value 4: To 5 values: If it fails, if an error is thrown 
iF RES == 1: 
    return HttpResponse ( 'e-mail sent successfully') 
the else: 
    return HttpResponse ( 'e-mail sending failed') 
`` `

         '[email protected]' 
         [ '[email protected]', '[email protected]']) 

message2 = ( 'Are you free this Sunday?',

         '[email protected]' 
         [ '[email protected]' '[email protected] ' 
the else:])
res = send_mass_email((message1, message2))
if res == 2:

class the SendMail (of the threading.Thread): 
    DEF the __init __ (Self, Subject, text, In Email, fail_silently = False): 
        self.subject = Subject 
        self.text = text 
        self.email = In Email 
        self.fail_silently = fail_silently 
        Threading the init __ .__ .thread (Self) 

    DEF RUN (Self): 
        send_mail ( 
            self.subject, 
            self.text, 
            settings.EMAIL_HOST_USER,
            [self.email],
            fail_silently=self.fail_silently
        )
```
