This section will show you how to auto-update email addresses of Contacts and Affiliation records to append '.invalid' to all email addresses in your newly created or refreshed sandbox. This will ensure unintended emails are not sent to contacts during testing processes. Be sure to also adjust Email Deliverability in Setup.

The Apex classes can be invoked via the following within the Developer Console > Execute Anonymous Apex.

fdnp_cf1.SetEmailToInvalidDuringSBRefresh refresh = new fdnp_cf1.SetEmailToInvalidDuringSBRefresh(); refresh.runApexClass(null);

The class can also be specified when initiating a sandbox creation or refresh to automatically execute the class after the sandbox is created.
