Not sure if you have "redirect" option after the PIPE command, at least I havn't seen one yet :-). But to solve your problem you can use something like :
call-home send "show run" email admin@mycustommonitor.com
of course you can do more with "Call-home" feature of the ASA as well as you will need additional commands and prerequisites like DNS setup etc to get it going.

Certainly I would prefer something like EEM on cisco asa well in coming future.
