Warning Banners

Overview

The Banners Action is an Enterprise feature that allows you to surface custom banners to mailbox users.

Banners are designed to fill the gap between high-fidelity Rules you set to auto-remediate and low-fidelity Rules that only generate alerts. This Action applies a banner directly to end user mailboxes, regardless of where they are accessing their email.

You can also customize the Banners to fit your organization's tone or workflows.

How to create a Banner

  1. Click on “Actions” in the left nav of your Dashboard
  2. Click on “New Action” and “Banner”
  3. Customize banner by setting a Banner Name, Background Color, Header and Body.
  4. Click “Save”
  5. Optional: Add Banner to existing rules

How to add Banners to Rules

  1. Click "Detection Rules" or “Automations” in the left nav of your Dashboard
  2. Click on the Rule you wish to add the action to, opening the detail view for this Rule.
  3. Click "Edit" or "Edit Metadata" in the top right of this detail view
  4. Click the "Actions" dropdown and select your Warning Banner Action
  5. Click "Save Rule"



How to add a Banner on a Message/Message group

  1. On the Message Detail View, classify the message
  2. Take optional banner action

How to delete a Banner

  1. On the Message Detail View, classify the message
  2. Hide the banner (only available if banner has already been applied).

What happens if multiple banner fire on the same message?

When multiple rules with different banners trigger on the same message, Sublime will show the highest priority banner you've configured.

Edge case behavior: If both a Detection Rule banner and an Automation Rule banner apply to the same message, email recipients may briefly see the Detection Rule banner before the higher priority Automation Rule banner appears.

How to set priority of banners?

  • Go to the Actions page
  • Click on any banner
  • On the top corner click "Edit Priority"
  • Move banners around (higher priority banners will be applied first)
  • Press Save


API Usage

When calling the Warning Banner default action via API, the highest priority warning banner will be added to the message. To apply a specific banner, use the custom action ID instead.
