Renee, the system does have a limit, per alert delivery run, of how many individual emails it will send, to avoid situations where it might send an unreasonable number of emails. The limit is configurable, and defaults as follows:
SEPARATE_EMAIL_DELIVERY_USER_LIMIT=50
You can add the above property to your override.properties file (if it doesn't exist, create it in the same folder as your IA.properties for your installation configuration), and run update-config. The modified property value ends up in alert.properties. You can increase it as you see fit for how many individual emails you want the system to send to any one user per run of the result action/alert processing that runs every 5 minutes.
