How to send a notification to a specific email based on an ID number.

Is it possible to send email only to person whose email id i have mentioned in text box at the time of submission of form. There can be one email id or multiple email id. The email id will not be same every time i submit the form, hence i will enter the email id in text box.

If you have all those emails and their corresponding ID in an excel file, you can populate the email field depending on the ID that was entered, here is a guide that explain how to use the Spreadsheet to Form widget: https://www.jotform.com/help/442-How-to-Use-the-Spreadsheet-to-Form-Widget

So, the email filled that will be populated with one of the email address from the spreadsheet, can be assigned as the recipient in a Autoresponder: https://www.jotform.com/help/26-Setting-up-an-Autoresponder-Email
