How to Send Emails to Multiple Recipients Individually Using Python

Introduction

Do you need to send emails to multiple recipients individually using Python? It is possible that you can do it. You can use send_mail module in Python. You can send emails to many recipients but there is a need to hide other recipients' emails for privacy.

Problem statement

We intended to send separate emails to a number of individuals using Python. In other words, the message is visible to anyone, but the recipients' emails are hidden. This is advantageous as an individual's email is private. We want to share with you how we resolved this issue in this article.

Background of the isue

Our website, (mcqsmonitor.com), specializes in multiple choice questions (mcqs) covering many research topics such as Mathematics, English, Geography, and more. We developed the sending emails to users function to notify users of the new MCQs posted to the website.

To accomplish this, We went to YouTube and found the video (Build a Newsletter Section for Your Django Web Application) to do this. However, the codes did not allow me to send emails to multiple recipients individually so that everyone sees the message but does not see the other recipients' emails. With our knowledge in Python, we thought of what we can do to deal with this issue.

Sending emails to multiple recipients

I will post the files (views, forms, models, urls and settings) need to change to send emails to recipients.

views.py

views for sending emails:

   <!-- Views function to let users subscribe to newsletter -->
   def index(request):
    if request.method == 'POST':
        form = SubscibersForm(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request, 'Subscription Successful')
            return redirect('https://mcqsmonitorlh.pythonanywhere.com/subscribe/')
    else:
        form = SubscibersForm()
    context = {
        'form': form,
    }
    return render(request, 'letter/index.html', context)

<!-- Views function to send to users newsletter -->
def mail_letter(request):
    emails = Subscribers.objects.all()
    df = read_frame(emails, fieldnames=['email'])
    mail_list = df['email'].values.tolist()
    print(mail_list)
    if request.method == 'POST':
        form = MailMessageForm(request.POST)
        if form.is_valid():
            form.save()
            title = form.cleaned_data.get('title')
            message = form.cleaned_data.get('message')
            send_mail(
                title,
                message,
                '',
                mail_list,
                fail_silently=False,
            )
            messages.success(request, 'Message has been sent to the Mail List')
            return redirect('https://mcqsmonitorlh.pythonanywhere.com/mail_letter/')
    else:
        form = MailMessageForm()
    context = {
        'form': form,
    }
    return render(request, 'letter/mail_letter.html', context)

urls.py

urls for sending emails:

from django.urls import path
from .views import (mail_letter,index)
app_name = 'name of you app'

urlpatterns = [
    path('subscribe/', index, name='letter-index'), # url for users subscribe
    path('mail_letter/', mail_letter, name='mail-letter'), # url for sending emails
]

models.py

models for sending emails:

from django.db import models
from django.urls import reverse

# Model for newsletters
class Subscribers(models.Model):
    email = models.EmailField(null=True)
    date = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.email


class MailMessage(models.Model):
    title = models.CharField(max_length=100, null=True)
    message = models.TextField(null=True)

    def __str__(self):
        return self.title

forms.py

forms for sending emails:

from django.db import models
from django.urls import reverse

# Forms for newsletter
class SubscibersForm(forms.ModelForm):
    class Meta:
        model = Subscribers
        fields = ['email', ]

class MailMessageForm(forms.ModelForm):
    class Meta:
        model = MailMessage
        fields = '__all__'

admin.py

admin.py for sending emails:

from django.contrib import admin
from . models import MailMessage, Subscribers

@admin.register(MailMessage)
class MailMessageAdmin(admin.ModelAdmin):
    list_display = ['title', 'message']

@admin.register(Subscribers)
class SubscribersAdmin(admin.ModelAdmin):
    list_display = ['email', 'date']

settings.py needed lines to send emails

settings.py for sending emails:

# Added for sending emails
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_USE_TLS = True
EMAIL_PORT = 587
EMAIL_HOST_USER = 'senderemail@gmail.com' #Enter your email
EMAIL_HOST_PASSWORD = 'sender email password' #Enter the password to the email

html files

You can find the html files from the above provided youtube channel (Build a Newsletter Section for Your Django Web Application) where there is github repository to clone the files.

Sending emails to multiple recipients individually

I just modify the mail_letter function in views.py above as follows.
