Automatic email representation in BPMN

Hello
I have a question regarding the process you can see below (which is actually 2 processes working together).

In the top process you can see that I have a user filling out a form and validating it. As soon as he validates it, the system generates automatically an email that is sent to the same person, to confirm that his request was submitted. I do not know how to model this. My best attempt is shown in yellow in the picture, however it does not seem right.
Please note I am NOT doing this with the intention of automating the process, I am just trying to represent business process model to better communicate with the business (so it is important to show an email is sent).
Thank you for your help
Elsa

It seems alright to me, what about it do you not like?
