My form has a text field to provide email (My domain email id, not external)
Requirement: User wants to send this form to a dedicated person in RFI's divison. So he is typing specific email id, is it possible to send the submit form to the provided email ID?
I tried to create a look up, but not working.
For debugging I would use a Log In History List action that has the the lookup configured the same way and see what is returned. That way you can tell if its the lookup that is the problem or the metadata that is being returned that is the issue i.e the format of the email address.
Try using Email service: External EMail and attachment. configuration in the email action. If it didn't work, move the text field vlaue to a variable and first print the variable to logs and see if there is an email in it and use the variable in the email action.
