{% unless current_user == nil or current_user.is_guest %}
  {% assign email_domain = current_user.customer.email | split: '@' %}
  {% if email_domain[1] contains "sitechcs.com" %}
    Success! You'll want ALL code currently in your 'Layout' to go here so the site loads.
  {% else %}
    If the user sees this text, it means they logged in, but their email domain isn't approved.
  {% endif %}
{% else %}
  If the user sees this text, it means they are not logged in. So you'll likely want to prompt them to login or auto redirect them to login page here.
{% endunless %}
