* After starting your campaign, the users will get a randomized URL sent via email that might look like this: https://phishing.withlucy.net/a5b371863fc2d6b5e2bf2bc2199597135f3db17c9a9194247002ae86e24c75ff.  This is a system generated link that cannot be altered! Each user gets a different link. If you have changed the link in the email manually, it will not work.
  * Another reason why the URL is not reachable anymore is when the campaign is stopped. Only when it is started will the URL work.
