Mass action not working

Hi. I want whenever an order is updated, send an email.

I've attached the screenshot of what i did.

what is wrong that this doesnt work ?

Hi,

This looks fine.
Could it be that the email is blocked by gmail or by your hosting email server being it thinks it might be spam ? Maybe you need to write real text in the subject and body of the email being sent ?
