I recently treated myself to a bag on sale at Kate Spade. The shipping confirmation email had a sentence with a tracking link in it. I looked at the email the next day and that sentence and link were gone and in their place it read that my package would be delivered the next day. I inspected the email and saw that it’s just a plain ole <p> tag within a table like any other email. I didn’t get a screenshot of the original message so I just posted one of what it says now. I also wish I had paid attention to the subject line because it says my package arrives tomorrow, too. I wonder if it also changed?
Either way I was curious how they did that? Or is this just a modern browser thing with tracking links now?
