Sometimes schools have firewalls in place that may filter emails from coming in and going to Spam.
Please have your recommender check their Spam/junk folders, note the email would be coming from firstname.lastname@example.org.
If you have an alternate email for your teacher/or recommender, you can log back into your account to change the email address of your recommender.
Steps to verify or change your recommender's e-mail address:
1.) Click 'Pending'.
2.) Then, click 'Go to Documentation Letters', you will see the e-mail address for the recommender.
3.) Please check the e-mail address for your recommender. If correct you can either re-send to that address, or change the e-mail address to an alternate e-mail address.
Note: Once a resend or change of email address has been applied, there is a 12 hour timeframe before a new resend or edit can be made.
