Normally, you do not need to whitelist for our demo. Since the emails in the course of our phishing demo are not sent via our main system, whitelisting based on the IP address, as we recommend for the phishing simulation, is unfortunately not possible.
However, there is a possibility to identify our e-mail. Our demo e-mails all contain the header
In the later simulation, if whitelisting via the header is necessary, a value unique to you can be stored here.
