Why am I receiving an "Unable to Locate Campaign" error?

If you click on a link and receive the "Unable to Locate Campaign" error page, that usually means the campaign was a test campaign that has been changed since the original sending (either by modifying settings, recipients or content).

If you are the user sending the campaign and receiving the error message when clicking on links, save any changes to the campaign and then send a new test. The links in this campaign will work correctly.

Or if you are a recipient of the campaign, contact the original sender of the campaign to let them know that you can no longer access the links and request they save any changes to the campaign and then resend to you.
