# Available For Mail App App Page

**`clients:availableForMailAppAppPage`**

Enables components to show up in the Lightning for Gmail or Lightning For Outlook Flexipages.

::::::tabset{tabs='["Develop", "Specifications"]'}

:::::tab

To add a component to a Mail App Lightning page in the Lightning App Builder, or email application panes in Lightning for Outlook or Lightning for Gmail, implement the `clients:availableForMailAppAppPage` marker interface. This interface is used with `clients:hasItemContext` and `clients:hasEventContext`to implement record-specific and event-specific information.

To ensure that custom components appear correctly in Lightning for Outlook or Lightning for Gmail, enable them to adjust to variable widths.

For more information, see the [Lightning Aura Components Developer Guide](https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/components_config_for_app_builder_email_app_pane.htm).
