Hi @tuanphan - here's what I have: 

<!-- MailerLite Universal -->
<script>
    (function(w,d,e,u,f,l,n){w[f]=w[f]||function(){(w[f].q=w[f].q||[])
    .push(arguments);},l=d.createElement(e),l.async=1,l.src=u,
    n=d.getElementsByTagName(e)[0],n.parentNode.insertBefore(l,n);})
    (window,document,'script','https://assets.mailerlite.com/js/universal.js','ml');
    ml('account', '357978');
</script>
<!-- End MailerLite Universal -->

I did a check for settings on the Mailerlite side from this article: https://www.mailerlite.com/help/how-to-troubleshoot-pop-up-forms 

Is there a block for custom code popups by external parties like Mailerlite?

We've inserted a code for custom popups in the Developer Tools > Code Injection > Header section but are not seeing the popup. 

The site is on Commerce Basic 

You can either transfer or point your domain name. If you transfer, then you would then be paying Squarespace for renewals.  If you point your domain name, then you pay the service provider that you pointing your domain from (e.g. InMotion or Network Solutions). 

Responding for future reference on pointing domain name from InMotion Hosting to a Squarespace site: This can be done from the CPanel. Log in to your Cpanel > go to the Domains section > select Domains > select Modify the Zones  and you'll see where you can edit the records based on the instructions Squarespace provides. Mine was up within 24 hours of making the changes.
