Django: send email on form submition - django

Question

I need to send an email after user submits a form on my page (this is still in development, but it'll be in production soon).
I've read this other answer but after my form is submitted I'm not reciving any email (I've used my personal email as the sender and the receiver, for testing).
What I need to modify?
PLUS: How to send images on emails? Any tutorial on this? I need to send professional emails after form submition.
settings.py
EMAIL_HOST = 'smtp.gmail.com' # since you are using a gmail account
EMAIL_PORT = 587 # Gmail SMTP port for TLS
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'oma.oma#gmail.com' #Not my actual email
EMAIL_HOST_PASSWORD = 'MyPassword' #Not my actual password
views.py:
# here we are going to use CreateView to save the Third step ModelForm
class StepThreeView(CreateView):
form_class = StepThreeForm
template_name = 'main_app/step-three.html'
success_url = '/'
def form_valid(self, form):
form.instance.tamanios = self.request.session.get('tamanios') # get tamanios from session
form.instance.cantidades = self.request.session.get('cantidades') # get cantidades from session
del self.request.session['cantidades'] # delete cantidades value from session
del self.request.session['tamanios'] # delete tamanios value from session
self.request.session.modified = True
return super(StepThreeView, self).form_valid(form)
form.py:
from django.core.mail import send_mail
class StepThreeForm(forms.ModelForm):
instrucciones = forms.CharField(widget=forms.Textarea)
class Meta:
model = TamaniosCantidades
fields = ('imagenes', 'instrucciones')
def __init__(self, *args, **kwargs):
super(StepThreeForm, self).__init__(*args, **kwargs)
self.fields['instrucciones'].required = False
def send_email(self):
send_mail('Django Test', 'My message', 'oma.oma#gmail.com',
['oma.oma#gmail.com'], fail_silently=False)

You can override the save method like this in your Last Form:
class StepThreeForm(forms.ModelForm):
def save(self, commit=True):
instance = super(StepThreeForm, self).save(commit=commit)
self.send_email()
return instance
def send_email(self):
image = self.cleaned_data.get('imagenes', None)
msg = EmailMessage(
'Hello',
'Body goes here',
'from#example.com',
['to1#example.com', 'to2#example.com'],
headers={'Message-ID': 'foo'},
)
msg.content_subtype = "html"
if image:
mime_image = MIMEImage(image.read())
mime_image.add_header('Content-ID', '<image>')
msg.attach(mime_image)
msg.send()
