Re: sending mail after task reload to specific group
Your best bet is to set up an Alert in QlikView. You will find these under Tools / Alerts in QlikView Desktop and I am sure you can find a description of how to set them up on QlikCommunity.
You will want to set the Condition to something that is always true (eg. 1=1), the event to Post Reload, Trigger Level to Always and Mode to Batch (you could add Interactive here to make it easier to test).
This will use the same SMTP settings to send a mail as failure notifications on the server us - so you will need to ensure these are set up correctly.
