Is there a way to get an instant notification email when a client checks in with the SEPM server?

There is currently no notification condition for this but if there was the amount of emails you would be getting would be very high. For example if you have your communication setup for pull mode with the default 5 minute heartbeat and you have 500 clients you would be getting 2500 emails per hour. If your environment is larger or heartbeat is set lower then this number would be even higher.

If you would like to add this to a enhancement request below documentation on how to do this.

I would want to know when one particular machine checks into SEPM, not all my machines.

I guess this is currently not possible?

Correct, currently this is not possible.
