There is companies that send email with invoices where you have to click a link. There is no way of logging in on their site to get to the invoice. It is an easy fix for them (we use the same invoicing company as they do so I know). All they need to do is click "Allow sending bills directly to customers bank". Every month I get the email, I use the included chat function on the webpage to ask when they will enable this and it's always not possible. Mabe some day.

I wish we could stop training people to click links in random messages just because we want to be able to track their movements online.
