In case you haven't seen this, Oracle Support will no longer be sending communications by email w.e.f. 1st Jan 2019:

Please be aware that with effect from 1st January 2019 all communications relating to UK localization product announcements such as Early Adopter invitations and patch releases will no longer be distributed by email. These will instead be communicated to you through the existing Communities ,Oracle E-Business Suite (MOSC ). This change is being introduced in part due to the introduction of the GDPR(PII) Law, and also to provide a consistent and improved means of distribution and communication to all Customers.

The communities are as follows;
• Human Capital Management - EBS (MOSC)

• Compensation and Benefits - EBS (MOSC)
• Payroll - EBS (MOSC)
