Will subusers also receive the email notification of the form shared with them

When I add a Sub User to an account and select a specific form for them to have access to, will they also receive email notifications when the form is submitted? 

No, they will not receive the email notification being sent every time your form gets submitted.

Only the email address(es) set as the recipient(s) of the email notification in your form will receive the email(s).

If you have any further questions, please do not hesitate to let us know.
