How to delete an email recipient address?

We have an account Oklahoma Employment Security Commission and Shalonda Sanders was on it but no longer is associated with this account.  She continues to get notices.  How can I take her off and keep her from receiving emails?

You need to check the email notifications on your form, to do it, you need to go to the settings tab and emails section, once there place the cursor on the email and click on the edit button:

Once in the email wizard, go to the recipients tab and there you will get the full recipient email addresses list, click on the "X" icon to remove the not desired addresses: 

You should also check if your form has conditions that trigger the emails, they look like this: 

If you find some, edit them and remove the email address from there, otherwise, emails will be still sent to that address. 

Hope this helps.
