A notification type can support email, push, in-app delivery, or a combination of them. Enable each channel where you want to receive that event.
Email sends the notification to the email address on your Tringify account. Use it when you want a durable copy outside Store Admin.
Push
Push sends the notification to supported devices where you are signed in to the Tringify app for this store. The device must allow notifications and have an active push token.
In-app
In-app delivery adds the event to your notification inbox in Store Admin and the Tringify app. Reading or opening an in-app notification does not change your email or push preference.
