It looks like you go support from the Atlassian Cloud support team at https://getsupport.atlassian.com.

The initial answer, in case it helps someone else in the Community, was something like:

> How do I know or check that my email is an Atlassian account? How do I check other users?

• You can try to login to this page: https://id.atlassian.com
  If you can have access to it, you have an Atlassian Account.

> How to bulk upgrade users based on your new policy?

• Unfortunately, it's not possible. To upgrade to an Atlassian account, your users follow a simple upgrade process.
