Banner over mail

You're referring to the popular phrase "Banner over Mail"!

"Banner over Mail" is a phrase used to describe the process of sending a banner or a notification over the email (mail) to alert someone of an important update, message, or notification. This phrase is often used in the context of digital communication, such as email marketing, customer service, or project management.

In essence, "Banner over Mail" means sending a visual alert or notification over the email to grab someone's attention, rather than relying solely on the subject line or body of the email. This can be particularly useful for important updates, urgent messages, or notifications that require immediate attention.

For example, if a team member needs to review a critical document, a project manager might send a banner over mail to alert them to the new document and encourage them to review it ASAP.

Does that make sense?
