recover email messages in Apple mail

[zio_mangrovia]

I lost some Gmail emails messages which were configured into iPhone with imap protoco of Apple mail.
I'm not able to find those emails it into gmail Account (no emails into trash folder) so I ask if there is way to recover mbox files, which are been deleted, by 3rd part tools.
I tried with dr. Fone but It is not able to find email messages but only typical apps, not reference to Apple mail app.

Have you tried logging in to gmail's web mail to see if they are there?

Have you tried logging in to gmail's web mail to see if they are there?

It was been the first thing which I made.
Does It exist log in iPhone to understand in Apple mail when this email message was been deleted ?

My assumption (which can be wrong at times) is that when you delete something, it is gone, which is why you get warning boxes asking if you are sure you want to do this.
