how to limit the sending of emails in django

Good morning:

On the website that I am developing, send an email to the owner of the product every time another user puts it in favorite and I have found that if you start clicking many times it will not stop sending emails to that person with the same message, then I want to know if there is any way to control that and that I do not repeat emails at least in a period of time Appointment in block

def dar_like(request):
    producto = Producto.objects.get(id=request.GET.get('producto'))
    perfil = Perfil.objects.get(usuario = request.user)
    notificacion = Notificacion.objects.get(perfil=producto.perfil)
    data = {'mensaje':'completado'}
    if Like.objects.filter(producto=producto,perfil=perfil).exists():
        like = Like.objects.get(producto=producto)
        like.perfil.remove(perfil)
        like.save()
        json_data = json.dumps(data)
        return HttpResponse(json_data, content_type='application/json')
    else:
        like = Like.objects.get(producto=producto)
        like.perfil.add(perfil)
        like.save()
        if notificacion.nuevo_seguidor == True:
            html = render_to_string('intranet/emails/like_producto.html',{'producto':producto,'perfil':perfil})
            msg = EmailMessage('Like a un producto tuyo', html, settings.EMAIL_HOST_USER, to=[producto.perfil.usuario.email])
            msg.content_subtype = 'html'
            msg.send(fail_silently=False)
        json_data = json.dumps(data)
        return HttpResponse(json_data, content_type='application/json')

this is the code, as you can check every time it enters the condition of the if it will send an email without any control

My model is this

class Like(models.Model):
    perfil = models.ManyToManyField(Perfil, related_name='likes')
    producto = models.OneToOneField(Producto)
