Then tell the school about email and to stop wasting their money!

I wish! Someone has obviously told them that SMS is 'the way forward'
or some such bollix, so that is what they do. As mentioned earlier,
they have a perfectly good web site that was updated with emergency
information [1], but that seems to have fallen behind the all new SMS
service.

[1] Rural school, so most pupils travel by school bus. The web site
used to be updated whenever busses were delayed or cancelled due to
weather, school closed etc.
