When a form is submited, and email is sent to an email address.
By default, this email address is not set up.
Please set this up.
NOTE
To send emails from the nonprofit organization through WordPress, you need to have an email address with the organization's domain name.
eg. jane@helpfulnonprofit.org
If the nonprofit doesn't have one and is using a generic email like Gmail or Hotmail, you can use "noreply@yourdomain.com" (replacing "yourdomain.com" with the nonprofit's domain name) as the reply address.
