Tags: Skills ACG

Follow these steps to configure your company's firewall and mail servers to ensure your users can access Pluralsight Skills and ACG.


Email

Please make certain you configure the following hosts as trusted senders on your email server and firewall so that mail from Pluralsight isn't rejected:

  • Sparkpost, IP addresses 192.174.86.231 and 192.174.86.230, @appmail.pluralsight.com

Please make sure admin@pluralsight.com and @appmail.pluralsight.com are not routed to spam. If you don't do this, your users may not receive their team plan invites and password reset emails.

If your organization elects into customer marketing communications—typically around adoption and engagement—please allowlist and configure this host as a trusted sender on your email server and firewall:

  • Marketo, @create.pluralsight.com, IP address 192.28.147.19

This is optional and only necessary for organizations that are working with Pluralsight and using customer marketing communications.
