Recommender not receiving invite

So my recommender just informed me that she has not received an email from common app. She has no spam folder , I spelled the email correctly, and apparently this has happened before. She has gotten around it by having students send the rec email to her home email, but I can’t change it because I already submitted my application. What do I do?

Have her send in a paper copy directly to the Admissions Office at whichever University you’re applying to - make sure identifying information is given clearly.

I’d recommend that you contact the Uni via e-mail first though, to see if they have another preference.
