Django verification email

Question

I have a Django app deployed on Pythonanywhere. Everything works as expected except for the verification emails.When a new user registers, he should receive a verification email, but Django doesn't send it until the admin panel is reloaded. All other emails(welcome emails, contact form emails) are sent without issue. When I test locally on my laptop verification emails are sent instantly. I am using django-email-verification and emails are sent through gmail.

views.py

class RegisterView(CreateView):
    form_class = RegisterForm
    template_name = 'common/register.html'
    success_url = reverse_lazy('login')

    def dispatch(self, request, *args, **kwargs):
        if request.user.is_authenticated:
            return redirect('index')

        return super().dispatch(request, *args, **kwargs)

    def form_valid(self, form):
        form.save(commit=False)
        user_email = form.cleaned_data['email']
        user_username = form.cleaned_data['username']
        user_password = form.cleaned_data['password1']

        user = UserModel.objects.create_user(username=user_username, email=user_email, password=user_password)

        user.is_active = False
        send_email(user)

        return HttpResponseRedirect(reverse('email sent'))

    def form_invalid(self, form):
        return super().form_invalid(form)
