 The Smart Alerts feature ensures that all outgoing mail items are compliant with the information protection policies of an organization and helps users improve their messages through recommendations. To ensure your add-in always provides users with a smooth and efficient sending experience, observe the following guidelines.
 
 - **Don't let your add-in further delay the send operation**. Smart Alerts add-ins must be short-running and lightweight. Avoid overloading the `OnMessageSend` and `OnAppointmentSend` event handlers with heavy validations. To prevent this, preprocess information when other events occur, such as the `OnMessageRecipientsChanged` or `OnMessageAttachmentsChanged` event. To determine which events your add-in can respond to, see the "Supported events" section of [Configure your Outlook add-in for event-based activation](autolaunch.md#supported-events).
-- **Don't implement additional dialogs**. Prevent overwhelming your users with too many dialogs. Instead, customize the text in the Smart Alerts dialog to convey information. If needed, you can also [customize the **Don't Send** button](smart-alerts-onmessagesend-walkthrough.md#customize-the-dont-send-button-optional) to provide users with additional information and functionality through a task pane or function.

 - **Enable the appropriate Group Policy settings in your organization**. To ensure that your Smart Alerts add-in activates on each mail item, including those sent using applications that implement Simple MAPI, configure the **Running Outlook for Simple MAPI Sending** setting. To learn more about this setting, see [Activate Smart Alerts in applications that use Simple MAPI](#activate-smart-alerts-in-applications-that-use-simple-mapi).
