There are two ways how to set an empty signature for a user.
The first way how to do that is in the Gmail settings of the specific user.
You can just erase it manually in the Gmail settings (Settings > tab General, scroll down to a signature part). Or you can switch to the option No signature in the same settings.
The second option is using SignatureSatori to push a "blank" signature.
You can prepare a new template called for example Empty signature in the section Users
Then erase everything and insert one empty space, because there always has to be something in the template to make it work
Save the template
Create a new User group and move there all users you want them to have an empty signature
Assign this new blank template to this User group
Click on Save
Click on Set signature to push the empty signature to all the users
Please note that you need credits or a subscription mode active to set the signature via SignatureSatori even though you push an empty signature.
If you want to prevent Users from having their signatures set up during Automation, you can exclude them manually.
