(ISC)² does not release scores. The thing you get via email is a notice that the back-end work has been completed and that you can now go onto their website and enter your endorsement information. However, the email is not a critical part of the process. You can always try to submit an endorsement. If the submission succeeds, the backend work was all completed and it is just the email that that failed. If you do discover that to be the case, you still ought to work our why email notices are failing. Places to look are in the email preferences on your member profile and in the junk mail folder on your mail reader.
