How do I resend Edit details to submitter?

If my understanding of your question is correct, you must be looking for the Edit Link in the email.

Please refer to our user guide: 

How-to-Let-Users-Update-Their-Form-Submissions-at-a-Later-Date

You can find the Edit Link in the Form Fields dropdown list

Let us know if you need further assistance.

After reading more, I realize that you probably meant the re-submission of the edit submision on the email.

In the form Autoresponder on your form, you will see the option Send on editing submissions -- make sure the option is checked, and that should do the resend.
