Hi Jayden, Email message customization isn’t available during the free trial. Once you subscribe to a paid plan, you will be able to customize both the subject and the message. Login to Formesign using the registered email > click Forms > click on the form to open it > Edit page will be displayed > click Responses > In the Responses page, click on the three dots more icon next to the Submitted status > click Notify respondent for confirmation emails or Notify collaborators for notification emails > follow the prompts to complete the email set up.
