HELP-Sent completed rental application on Zillow to new applicant

[Alys Brown]

I have a rental posting on Zillow. I just sent a completed rental application including SSN to 3 new applicants. I thought it was a blank application.

1) Can I delete the email or attachment before they read it? If I cancel the entire listing, will it block people from reading emails?

2) What should I do to protect the applicant whose information was shared? I will definitely call her as well as pay for a service, if that's advised.

I am sick about this. Thanks for any quick advice.
