Send email from LN session after specific actions

Hello all.
We have a request and we need your expertise since we have never done something similar.

We are using LN 10.5 and from Order session (tdpur4100m000-tdpur4100m900) when an order is submitted (there is a change in the status) we want to send an email to specific users so as to let them know.Is it possible?If yes, using which LN functionality?

Any ideas?Please advice.
Thank you in advance!
