I just received an email from a company with this line in the footer:
Clicking the link immediately unsubscribes you, without confirmation. Now yes, this is appropriate for an unsubscribe link, but the text implies the link takes you to a settings page of some sort, rather than taking action. The action wording comes after the link. I didn’t see that part until after I clicked and got the “you’re unsubscribed” page. Bad design.
