Improve notification email to end users when domain is verified and accounts become managed

Problem Definition

When a domain is claimed, we send an email out to the Organization Admin:

Hi <End User>,

We're writing to let you know that your Atlassian account is now being managed by your Atlassian Cloud administrator.

This won't change the way you log in to Atlassian products or how you use them.
However, from now on if you want to update your email address, you'll need to contact your Atlassian Cloud administrator.

Important details are omitted such as:

1. The atlassian cloud administrator
2. The atlassian cloud url
3. For IDP initiated SAML, the SSO admin (as it would directly impact the way users login)

Suggested Solution

Include more details in the notifications so there is less ambiguity in terms of why the information is necessary for the receiver
