> Update: GCM is deprecated, use FCM
After Google replaced C2DM with GCM, they took off all limits.
SOURCE: http://developer.android.com/google/gcm/c2dm.html#history
Prior to GCM (when it was still called C2DM): https://developers.google.com/android/c2dm/#limitations)
The only limits you run into the GCM documentation is this: http://developer.android.com/google/gcm/adv.html#lifetime</s>

I am not sure if this is relevant to your question though.

There is a limit of 1000 notifications at one go.
Assume you have 50000 regids. You cannot send all 50000 together. After the first 1000, you will have to separately select the next 1000 and so on.

Doesn't seem there's a set numerical limit, but there are throttling measures in place.
> To prevent abuse (such as sending a flood of messages to a device) and > to optimize for the overall network efficiency and battery life of > devices, GCM implements throttling of messages using a token bucket > scheme. > > If an application collapse key exhausts its supply of available > tokens, new messages are buffered in a pending queue until new tokens > become available at the time of the periodic grant.

Edit/Update:
Just to update, the doc for throttling can now be found in the GCM Advanced Topics: http://www.androiddocs.com/google/gcm/adv.html#throttling
Solution 4 - Android
There NOT any daily limit for number push notifications (GCM) but Via Official Source GCM Advanced Topics it states that
>There is a limit on how many messages can be stored without collapsing. That limit is currently 100. If the limit is reached, all stored messages are discarded. Then when the device is back online, it receives a special message indicating that the limit was reached. The application can then handle the situation properly, typically by requesting a full sync.
Hope it will Help.

Tried to send over 1000 pushes from java code com.google.android.gcm.server.Sender "send" method, attempt fails.
https://developers.google.com/cloud-messaging/http-server-ref For Downstream HTTP messages (JSON):
param name - registration_ids type - String array
This parameter specifies a list of devices (registration tokens, or IDs) receiving a multicast message. It must contain at least 1 and at most 1000 registration tokens.
Use this parameter only for multicast messaging, not for single recipients. Multicast messages (sending to more than 1 registration tokens) are allowed using HTTP JSON format only.
Solution 6 - Android
According to the offical document, NO limit.
Solution 7 - Android
You can send Max 1,000 devices per SEND_ID !
Here is original source.
Solution 8 - Android
registration_ids This parameter specifies a list of devices (registration tokens, or IDs) receiving a multicast message. It must contain at least 1 and at most 1000 registration tokens.

Since GCM moved to firebase now, messaging service is totally free.
