loop issue when inviting users - django

Question

I am having trouble finding out my mistake. In my app I am creating a user that is set as inactive and then sending to those users a mail invitation to join my app. I set it up to be able to send multiple invitations but it only send one on the X invitations. So if I invite 5 users, only on mail is sent and 1 user created instead of 5. I guess there is something wrong with my loop but cannot find what..
here is my code
views.py:
def TeamRegister2(request):
InviteFormSet = formset_factory(InviteForm2)
if request.method == 'POST':
formset = InviteFormSet(request.POST, prefix = 'pfix')
if(formset.is_valid()):
for i in formset:
mail = i.cleaned_data['Email']
user = MyUser(email = mail)
password = MyUser.objects.make_random_password()
user.set_password(password)
user.is_active = False
user.is_employee = True
user.save()
u1 = user.id
a1 = MyUser.objects.get(email = request.user.email)
a2 = Project.objects.filter(project_hr_admin = a1)
a3 = a2.latest('id')
a4 = a3.team_id
a4.members.add(u1)
current_site = get_current_site(request)
message = render_to_string('acc_active_email.html', {
'user':user,
'domain':current_site.domain,
'uid': urlsafe_base64_encode(force_bytes(user.pk)),
'token': account_activation_token.make_token(user),
})
mail_subject = 'You have been invited to SoftScores.com please sign in to get access to the app'
to_email = user.email
email = EmailMessage(mail_subject, message, to=[to_email])
email.send()
return HttpResponse('An email have been sent to each Team member asking them to join in')
else:
print("The entered form is not valid")
else:
formset = InviteFormSet(prefix= 'pfix')
return render(request,'team_register.html', {'formset':formset})
form.py:
class InviteForm2(forms.Form):
"""
Form for member email invite
"""
Email = forms.EmailField(
widget=forms.EmailInput(attrs={
'placeholder': "Member's mail",
}),
required=False)
team_register.html:
{% extends 'base.html' %}
