Well, this should do it:

HEAD http://google.com/ | grep -q '200 OK' || mail ...

Use whatever URL is appropriate, and finish the mail command

Note that it doesn't exactly check that Apache is up, but if that machine
is reachable from the machine where you run the command, it'll check if
Apache is responding.
