If your test notifications are showing a different domain instead of your store domain, don’t be concerned. The reason this is happening is that when you signed up to your store’s push notifications, you did so from a domain that wasn’t your store.
Here are a couple of examples as to when this might happen. When you create a Firepush account, we ask you to subscribe to notifications from your store. But as you’re in the Firepush dashboard at that time, your test notifications will use the ‘dashboard.firepush.com’ domain.
Similarly, if you sign up to notifications via your store preview while in the Shopify dashboard, you may see ‘shopifypreview.com’ as the sending domain on your test notifications.
However, please be reassured that when you send out push notifications to your customers for real, these will show your store domain.
