Link for an email sent by Dropbox and my sent mailbox on my MAC

how do I set up a link for an email sent by Dropbox to show in my sent mailbox on my MAC

I must have done things the right way when I downloaded the free program because I went into my inbox a few moments ago and found the Dropbox emails that I had sent via Dropbox in my inbox.  It is logical that it shows there because it was sent by the Dropbox application and received in my inbox.  It does not make sense to me that it would show in the sent mailbox when it is already in the inbox.  If anyone disagrees, please let me know because I am at the learning stage.  Thanks
