I get no mail when one of my rigs is down. It worked after I switched my account to an other e-mail. But the only thing I got was "The following rigs seems down..." once. After restart it shows up as online in the dashboard but never got an mail that it's back online.

Since then I never got an mail when the rig is down.

I realy like your tool and I would donate on a monthly basis if it would send out e-Mail. Maybe there is something i missed (checked spam already)
