CivWorld got back to me today about my complaint about being unable to unsubscribe from the newsletter. Basically saying that they didn’t know why it bounced but they’d removed my email from the list manually. While double checking the email address I’d sent the unsubscribe to I realized what exactly had gone wrong. When they coded the template for the newsletter they coded the email address incorrectly. Basically if I manually type in the address as shown it works fine, but if I click on the email address (cause its clickable) the coded version was incorrect. Simple typo from the looks of it. I advised them of the error along with thanking them for taking me off the list.
