Question

Quick question, I read that Microsoft throttles toast notifications to 500 per day per subscription… I’m just checking… but thats per phone right? Not per server sending out toasts? so if I have 1000 devices receiving 1 toast thats ok, but sending 1000 toasts to 1 device==bad … right?

Cheers

It sounds to me like this is per-phone. You can however remove this limit if you authenticate your server. From MSDN:

We recommend setting up an authenticated web service to send your
notifications to the Microsoft Push Notification Service, because
communication occurs over an HTTPS interface for better security.
Authenticated web services do not have a daily limit on the number of
push notifications they can send. Unauthenticated web services, on the
other hand, are throttled at a rate of 500 push notifications per
subscription per day. For more information, see Setting Up an
Authenticated Web Service to Send Push Notifications for Windows
Phone.
