Account Owners & Program Managers have access to resend recommendation request emails, as well as edit the address it is sent to. Emails are able to be resent once every 12 hours, by either you or the applicant.
To resend or edit a recommendation email, click on an application and then navigate to the Documentation tab. From here you will see a Resend button next to the email address.
Here, you can type a new email address in the box, or just resend the request. You can only do so once every 12 hours, if the email has been resent recently you'll need to come back when the 12-hour window passes.
