“Deleted” emails?

Hi,
I seem to see a lot of deleted emails in the history. We have a lot of forms on the site, The forms are handled by the “Contact Form 7”, plugin mail is sent by “Post SMTP” using the Google API.
The deleted mails does not reach our mailbox, but not all mails are deleted:

History examples:
Deleted skickat e-postmeddelande “Privat: Ang. unders?kning”
Deleted skickat e-postmeddelande “Fettsugning”
Deleted skickat e-postmeddelande “Privat: F?rfr?gan fr?n hemsidan om Br?stf?rstoring: Br?stf?rstoring”

The most recent plugin aside from Simple History was Wordfence, could that somehow interpret filled out forms as a threat and delete them before they are sent?

I don’t have any users logging in to the site, aside from myself.
