Maximum iMessages per day?

My company has about 350 iphone users.  I would like to send them iMessage notifications from a MacBookPro.  Does anyone know if there is a limit on daily messages sent per device?  I read that there might be a ceiling of 300 messages per device per day but this was referring to phone to phone messaging.

A year ago there were discussions of measures that Apple might take to limit iMessage spam, but the Apple iMessage pages still say it's "unlimited".

I did find a page listing limits on iCloud messages to 200 per day and 100 addressees.

My guess is that what you want to do is possible. I'd be sure to give people a way to opt out of the messages, though, and do my best to honor their requests.

I wrote an applescript to send the messages from an IMac.  As long as the wait time beteween each message was long enough,  I did not hit any limits and was able to send 350 messages in about 4 hours.

set mytext to "message to be sent"

set addresses to "+81801035XXXX
<<list of phone numbers here>>
<<one line per entry>>

set text item delimiters to ";"
repeat with l in paragraphs of addresses
tell application "Messages"
set targetBuddy to l
set targetService to (id of 1st service whose service type = iMessage)
set textMessage to mytext
set theBuddy to buddy targetBuddy of service id targetService
send textMessage to theBuddy
log l
on error
delay (random number from 10 to 20)
end try
delay (random number from 10 to 20)
end tell
end repeat
