Contact 7 with payment gateway

We have just starting using this plugin after numerous issues with another that was designed for syncing Contact 7 forms with PayPal (or stripe) and not working properly. This plugin does work, however our only concern is that as another reviewer commented that notifications are only sent on successful completion after returning from paypal, not right after submitting the form. This may result in not getting a copy of all completed forms if a customer doesnt finalise the payment process.
