If you’re using the same HTTPS origin (domain or subdomain), subscribers will be automatically re-subscribed to PushAlert the next time they visit your site. No prompt will appear, and they’ll start receiving push notifications from PushAlert right away. At the same time, they should stop receiving push notifications from your previous provider.

Due to browser security restrictions, it’s not possible to import existing web push subscriptions directly. Instead, PushAlert will register subscribers when they return to your site.

Importing existing subscriber base is only possible if you are using your own HTTPS domain or sub-domain configuration with the previous provider.
