Under Multiple Recipients, there are 2 settings: Max recipients and Message type.

When a message is submitted to be sent out to a Group (with about 100 recipients), how should setup these settings?

If i set the Max recipients to 50, and then set message type to Separate Message – when the user submits a message with the plugin attempt to send 2 separate email notifications to 50 users (during that one submission)?

I am receiving a time out error (504) after submitting to a group (not when sending direct message to other users), and i am wondering if this is the cause (tiring to process multiple email notifications or one big 100 user notification).
