Turn off copies of all sent emails

Why do I receive a copy of all emails from ZimmerSoftware?
Copies of emails are still being sent to our customer
I receive every email I send to my guests myself. Can this be disabled?
Open Settings/Email&Chat.

At the top you will find the option Correspondence Email.
Set this option to Disabled.
After that, copies of emails sent from ZimmerSoftware will no longer be forwarded to you.
