Preferable way: Create Campaign each time or send event for repeated notifications

Question

Hello, We would like to notify mobile users about new movies or episodes of show. We are considering to use Pinpoint for this purpose.
To send notification to all Android users for example we need to create immediate campaign. But I have a doubts that this is a correct way, looks like Campaign is a long term entity? Do I need to delete and recreate campaign to send messages to auditory targeted be specific attribute? Or maybe is preferable way to create a Campaign which will be triggered by specififc event, as I understand is not strictly requirement to send messages from client app, we are able to send custom events from backend without setting optional fields like AppVersion and etc related to client app?

Answer

I am having trouble understanding your question. Are you trying to figure the best method to send messages to your users?

If so, how many users do you have on a daily basis?

Answer

An Event triggered campaign makes more sense in this case. You would create a Dynamic Segment with the users interested in such movie genre, or topic and create a Custom Event in the Pinpoint Event Stream when you are releasing a new movie that matches that topic. The campaign will send the message to all the users in that dynamic segment when the event occurs.

Keep in mind that you need to use a Dynamic Segment for your event-based campaign, and you need to enable the Event Stream in your project for this to work properly.
