okay…I see….for further clarification:

“For example: for the setting: “Email sending interval” 5 min; “Emails send per interval” 10”

For that specific setting, with the assumption that they all choose the setting to have the messages forwarded to their emails. What if 100 different users send separate messages to different recipients at the same time (meaning that one sender sends a message to one recipient and total 100 messages), will all the messages be forwarded to the emails simultaneously? or it will take 45 mins for 100 messages to be forwarded?
