Will sub accounts be able to delete submissions

I bought a plan that allows for  sub accounts I want those sub accounts to be able to manage and delete submissions as needed, are they able to do so?

Yes. It is possible to delete the submissions on your JotForm by the sub-account holders. Assigning the sub-account users to view the submissions on a form will enable them to view/edit/delete the submissions on the shared form. Please refer to the following guide that provides information about sharing the forms with sub-account users.
