How do websites know when my form is incomplete and send me reminder emails to finish?

665 views

I left items in my shopping cart and then I got an email asking if I’m still interested in buying them. On a course registration page I filled out the form but didn’t click submit and deleted some information. Then I got an email saying I should finish the form and enroll. It seemed creepy since I didn’t submit my email to them at all

1. You click to start the form or add something to your shopping cart.
2. Website says to its server, “Hey this guy just started his form, by the way.” The server saves this information. It knows who you are because you are logged into the site. This happens without you doing anything.
3. You leave without finishing the form or buying the item.
4. After some time (determined by the designer of whatever app you are using), the server will look up unfinished items -> then look up who they belong to -> then look up which email they have on file -> then send you a reminder.

If you completed the item or finished the form, then your name would be cleared from the “pending orders” data.
