Hi @D.A White
Thank you for posting this in Microsoft Q&A.
The transition to role-based access control (RBAC) should not affect your login or your ability to publish your website or web pages SQL access. This email is for customer who still have classic administrators in their tenant. And there are many customers who are still working with classic administrators to login to Azure portal. Do not have to worry about this email if you do not have any classic administrators in your Azure subscription.
Hope this helps. Do let us know if you any further queries.
Thanks,
Navya.
