How to send e-mail in django ?

#django #python

In django we can send e-mail using SMTP (Simple Mail Transfer Protocol) service which is inbuilt package in python and also in django.

What is smtp ?

SMTP (Simple Mail Transfer Protocol) is service that provides service to send, receive, and or relay outgoing mail between senders and receivers.
SMTP service takes your client email address(you can also give multiple email address) which you are using and it is formatted as smtp.gmail.com because let's take and example Gmail’s SMTP server address is smtp.gmail.com, and Twilio Send Grids is smtp.sendgrid.com. You can generally find your SMTP server address in the account or settings section of your mail client.

Django email sending setup

Step 4 --> Now install app in settings.py and this file will be in emails folder

Step 5 --> Now you need to migrate the project using command
python manage.py migrate

Step 6 --> Go in settings.py and go at the bottom and write code under static variable

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'gmail account email id'
EMAIL_HOST_PASSWORD = 'Your gmail password'
EMAIL_USE_TLS = True
EMAIL_PORT = 587

Here in variable EMAIL_HOST_USER you need to write the email id which have two step verification off because we need to make some settings change on your g-mail account. And In variable EMAIL_HOST_PASSWORD you need you write your g-mail account password.

Step 7 --> Now open your favorite browser and follow below steps

Go in option Account
Go in option Security and search for Less secure app access and turn that on because if you will not turn that on then django will not able to send the mail.

Step 8 --> Now create form.py file in mail folder and write code below code

form.py

from django import forms

class ContactMeForm(forms.Form):
    first_name = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control', 'placeholder':'Enter first name'}), required=True)
    last_name = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control', 'placeholder':'Enter last name'}), required=True)
    emailid = forms.EmailField(widget=forms.TextInput(attrs={'class':'form-control', 'placeholder':'Enter email id'}), required=True)
    phone_number = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control', 'placeholder':'Enter phone number'}))
    subject = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control', 'placeholder':'Enter subject'}), required=True)
    message = forms.CharField(widget=forms.Textarea(attrs={'class':'form-control', 'placeholder':'Enter Message'}), required=True)

Step 9 --> Now go in views.py file and write below code

views.py

from django.shortcuts import render
from main.form import ContactMeForm
from django.core.mail import send_mail, BadHeaderError
from django.http import HttpResponse
from django.contrib import messages

def home(request):
    form = ContactMeForm()

    if request.method == 'POST':
        form = ContactMeForm(request.POST)
        if form.is_valid():
            # form.save()
            # send_mail(subject, message[fname, lname, email, phonenumber, subject, message], sedner, recipient)

            subject = "Contact form inquiry"
            body = {
                'first_name': form.cleaned_data['first_name'],
                'last_name':form.cleaned_data['last_name'],
                'email': form.cleaned_data['emailid'],
                'phonenumber': form.cleaned_data['phone_number'],
                'subject': form.cleaned_data['subject'],
                'message': form.cleaned_data['message'],
            }

            message = '\n'.join(body.values())

            sender = form.cleaned_data['emailid']
            recipient = ['gameforyash@gmail.com']

            try:
                send_mail(subject, message, sender, recipient, fail_silently=True)

            except BadHeaderError:
                return HttpResponse("Invalid header found.")

            messages.success(request, "Your respoce has been submited successfully")
    context = {
        'form':form,
    }
    return render(request, "home/index.html", context)

Step 10 --> Now create urls.py file in main folder
Directory preview

Step 11 --> Open urls.py created in main folder and write below code

from django.urls import path
from main import views

urlpatterns = [
    path('', views.home, name="home"),
]

Step 12 --> Now register urls.py created in main folder to emails>url.py as shown below

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('main.urls'))
]

Step 13 --> Now create templates folder in main folder and create home folder in templates folder and create index.html in home folder

SOME THING LIKE THIS main>templates>home>index.html
Directory preview

Step 14 --> Open index.html and write below code

<!DOCTYPE html>
<html lang="en">

    <head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
