In some rare cases, the generated unsubscribe link in your campaigns ends in a “404 – Not Found” page. The same can happen for the confirm, profile link, and sometimes for every link which uses the tracking feature.
- Mailster is installed and activated
- Permalinks work correctly
- You have set up a newsletter homepage
- Your server can handle redirects
If you have Mailster activated the first thing you should do is reset your permalink structure. Go to Settings => Permalink and click on the save button.
If your links still don’t work you should ask your host or provider for help.
