What it is doing
This is a plain text security alert email with minimal formatting. It uses a clear hierarchy to present the critical information: what happened, when, where, and what to do next. The call to action is a simple text link, reinforced by security advice in the footer.
Worth stealing
The email effectively uses a plain text format to convey urgency and important security information without distractions.
