how to send a form that the user has filled in to my email with python kivy?

Question

My goal is that the form filled by the user send me an email with the fields filled, when the user click 'complete registration'

My file.py

class Cadastro(Screen):
    def pop(self):
    box = BoxLayout(orientation='vertical', padding=10)
    botoes = BoxLayout()

    pops = Popup(title='Concluido', content=box, size_hint=(None, None), size=(200, 100), 
                  auto_dismiss=False)

    ok = Button(text='Enviar', on_press=pops.dismiss)

    botoes.add_widget(ok)

    box.add_widget(botoes)

    pops.open()

part of my file . Kv:

Button:
    text: 'Concluir Cadastro'
    size_hint: .2, .1
    pos:500 , 2
    background_color:0,0,255,0
    on_press: root.pop()

Gratitude if someone can give me a help :)
