Apple Push Notification: Sending high volumes of messages

Question

I am using PHP to connect to apns to send some notifications to multiple devices, although the question is more conceptual so it doesn\'t have to be specific to

Answer 1

I've read that apple does care about the number of connections you make to their servers but I've never heard about any write limits. Also, I'm not sure about what kind of response you'd receive here, but it might be worth a try to see what happens. Maybe experiment with the sandbox push notification server, only using the device tokens of the production devices. Those phones should not receive any push notifications sent to the sandbox server and if the sandbox reports "delivered successfully", that would be a worry-free way to test.
