Important Notes:

1) Only an account owner or the owner of the hotlist can delete the hotlists created.

2) Deleting a hotlist does not delete the records inside the hotlist :)

Deleting a hotlist is really simple:
​
First, Click on the "Quick View" button on the top left of the screen.

If you are viewing candidates, you will see candidates hotlist and so on for Contacts or Jobs. .

Then click on the "View/Rename Candidate Hotlists" button

You can then Edit and delete any hotlist you want:

Hope this helped :)
