Last time I checked, crm_mon is not well suited for this purpose.

crm_mon has the following option

       -T, --mail-to=value
              Send  Mail  alerts  to  this  user.    See   also   --mail-from,
              --mail-host, --mail-prefix

But you will end-up with obscene amount of e-mails, I was blocked from gmail when I tried to use it once :)
For one resource failure you will get 4 e-mails: monitor,stop,start,monitor. Now imagine if it was a most significant member of a group or worse, node failure...

nagios would be better suited for this purpose, but, unfortunately, crm_mon is broken (http://developerbugs.linux-foundation.org/show_bug.cgi?id=2344) for quite awhile.

I am yet to find a good monitoring solution for pacemaker, hopefully somebody had more success and will share.

Thanks,
