Sometimes a guest has difficulty locating the invitation from the self-service-portal within their email inbox. Here are some potential solutions:

• The invited guest should examine their spam folder, as there exists a possibility that the invitation may have been erroneously classified as spam.
   
• The inviter is advised to check the accuracy of the guest's email address.
   
• The inviter can expunge the existing invitation and extend a fresh one to the guest, thereby the transmission of a new email notification.
