Then you can create input parameters to get them from and to, in this case, sender and receiver... You need to get which user you want to send the email to. And if you want to send multiple emails you need to adapt your logic.
Do you have any programming background or did you do the training? or guided path?
I would advise you to at least follow one guided path before doing this. That way you will be more prepared. And you can work on your project at the same time
I advise you to go for reactive https://www.outsystems.com/training/paths/18/becoming-a-reactive-web-developer/, if you want more logic and understand the platform I would go for traditional, but that is going to be deprecated.
And if you have any questions, before asking some questions look on the forums, maybe there was already someone with the same problem as yours! :)
All the best!
