The first thing to do is to check your junk/spam folders.
If you are certain that you should be receiving emails and you're not seeing them in your inbox, promo, junk/spam folder, and you are using a school/government/company email address, this can be related to strict school/government/company email server filtering. Please ask your IT support to make sure that all emails from skate4concrete.com and wpengine.com can be delivered to your email server and inboxes.
Why WPEngine? Skate4Concrete is hosted by WPEngine and emails sent through the website server are sent on behalf of wpengine.com.
This is more likely to affect emails containing Magic Links used to login and emails to reset your password.
If you continue to have issues, you can contact Crystal Howard directly by sending an email to crystal@project-cornerstone.org.
