Help Understanding HubSpot Domain Removal Notification

Hi everyone,

I received the attached message from HubSpot saying I need to “remove primary HubSpot (system) domains by 23 Jun 2025” due to a change in my plan. I’m a bit unclear on what exactly this means.

  • What are “primary HubSpot (system) domains”?
  • What will happen if I don’t take any action?
  • Will this affect my email sending, website pages, or other HubSpot tools?
  • Can I upgrade my plan or switch to a different setup that avoids these system domains?

I’d appreciate any clarification or guidance. Thank you!


Best,
Katya

Hi @KHarwood4! I’ve seen these types of emails when accounts have removed hubs and can no longer attach a domain to a HubSpot feature, since they don’t have the feature anymore! For example, when an account decides not to renew Service Hub, they no longer have access to a connected knowledge base domain, because they no longer have a HubSpot knowledge base! Have you made any big changes like that recently?
