Knowing I had to look out for something spotting the IPS was easy. Don’t know if it would have been as obvious without knowing something is wrong. But I receive so many fake parcel emails (at least at one of my email addresses) that checking the website/app rather than klicking a link is the default option. And I usually add the email adress of the legitimate shops to my contacts so I can easily filter out emails from new e-mail addresses and ignore them.
