Notifications (OrchardCore.Notifications)

The Notifications module provides the infrastructure necessary to send notification to the app users.

Notification Methods

There are many methods to send notifications to a user (e.x., Email, Web Push, Mobile Push, SMS, etc.). In addition to the notification center, OrchardCore is shipped with Email based notification feature. To allow users to receive notification via email, enable the Email Notifications feature.


When using Email Notifications feature, you must also configure the SMTP Service. When multiple notification methods are enabled, the user can opt-in/out any method they wishes to receive by editing their profile.

Adding Custom Notification Provider

To add a new notification method like Web Push, Mobile Push or SMS, you can simply implement the INotificationMethodProvider interface. Then, register your new implementation. For example, in the Email Notifications feature we register the email notification provider like this

public class EmailNotificationsStartup : StartupBase
    public override void ConfigureServices(IServiceCollection services)
        services.AddScoped<INotificationMethodProvider, EmailNotificationProvider>();

How to send a notification

You can send notification to a user via code by injecting INotificationService then calling the SendAsync(...) method. Alternatively, you can use workflows to notify a user about an event that took place.

Workflow Activities

When OrchardCore.Workflows feature is enabled, you'll see new activities that would allow you to notify users using workflows. Here are some of the available workflow tasks - Notify Content's Owner Task - Notify User Task
