Triggering BPM/Message from an XI Alert

I would like to trigger a BPM from an alert (like a mapping error) being generated but the only options are email, fax and SMS.

I could send out an email and receive it back within XI to kick off a process; but this is not elegant and email is not a guaranteed delivery mechanism plus the BPM should be triggered ASAP.

Anyone have any ideas?

Info to SAP - Would be good to add an additional option to send a message to XI as a feature to the alert framework in the future.

Regards,

Matt
