Subscribes - we use MC at work, well, Comms do, and they always have some tale of woe about why they can't do what we'd like.
Does either of you know how many emails MC can/will send daily? Local Govt paid-for-account, btw. I seem to recall Comms saying summat about 400 emails at a time or per day (was it?). Which is piss poor as we need to send 22k over a week or so soon.
