Emails sent to me from jot form have the name of a person who previously completed and submitted a form in the "from" section of the email

I would like to to apologize for the inconvenience. I'm not sure which forms on your account are you having issues with. Can you provide us the link to your form or the name of your form at least, please? 

I would suggest you try to check how your email notification was set up using this guide: Setting-Up-Email-Notifications

We will wait for your response. Thank you.
