How to Delete a Subdomain in Hubspot Domain Manager

Managing domains correctly in Hubspot is essential when you rebrand, restructure your website, or retire an old site section. Deleting an unused subdomain helps keep your Domain Manager clean and prevents visitors from hitting outdated or broken URLs.

This guide explains what it means to delete a subdomain, what changes inside your CRM and website tools, and how to safely remove a subdomain from your account.

Before You Delete a Subdomain in Hubspot

Before you remove any subdomain, review how it is used across your Hubspot tools. Deleting a connected host only affects content and settings that rely on that specific subdomain; other domains and subdomains remain active.

It is important to understand which tools are connected to your host so you can avoid unexpected issues for visitors, marketing campaigns, and sales assets.

Typical Reasons to Delete a Hubspot Subdomain

• You have retired a branded microsite or campaign site.
• You migrated content to a new subdomain or root domain.
• You are consolidating multiple regional or product URLs.
• You want to remove test or staging subdomains from Domain Manager.

Confirm that any forms, pages, or links using the subdomain are either no longer needed or have been moved to another live host.

What Deleting a Hubspot Subdomain Actually Does

When you delete a subdomain from settings, Hubspot removes the host from Domain Manager and disconnects it from tools that were using it. The change does not affect other active domains or brand domains in your account.

This has several effects across the account.

Impact on Hubspot COS and CMS Content

• Any website pages, landing pages, or blog posts hosted on that URL will no longer be available on the deleted subdomain.
• If content is still needed, you should move it to another connected host before you remove the original one.
• Visitors who try to access the old URLs will no longer see live content after the host is deleted.

Impact on Redirects Managed in Hubspot

• URL redirects that target the deleted subdomain will no longer work as expected.
• Redirect rules that point to or from that host should be updated to use a different connected domain if required.
• If your goal is to keep visitors flowing to a new domain, create redirects on the destination domain before you delete the old host.

Effect on Tools That Depend on a Primary Hubspot Domain

Some features use a selected primary host, such as email subscription pages, system pages, and default forms. If the subdomain you plan to delete is set as a primary domain for any tool, you should assign a different active host first. Otherwise, those tools can lose their default URLs.

Steps to Delete a Subdomain in Hubspot Domain Manager

The actual process to delete a subdomain is handled inside Domain & URLs settings. Follow the steps below to remove a host safely.

1. Open Domain & URLs Settings in Hubspot

1. Log in to your account with a user that has permission to edit domains.
2. In the main navigation, go to your settings area.
3. In the left sidebar, select the domain and URL configuration section.

Here you will see all brand domains and subdomains that are connected to your account.

2. Identify the Subdomain You Want to Delete

1. Locate the correct brand domain group.
2. Find the individual subdomain or host name that you want to remove.
3. Confirm that it is not set as the primary host for website, landing pages, blog, or other content types that still need to be live.

Take a moment to verify that no important pages are still relying on this host.

3. Remove or Reassign Dependent Content

Before you delete the host, clean up any affected content:

• Move key pages or blog posts from the old host to another active subdomain.
• Update links in emails, workflows, and CTAs that still reference the soon‑to‑be‑deleted URLs.
• Reassign primary domains for tools that are using the host as their default.

This preparation step helps maintain a smooth visitor experience and prevents broken links inside your Hubspot account.

4. Delete the Subdomain

1. In the Domain Manager list, click the options or actions menu next to the host you want to remove.
2. Select the delete or remove host option.
3. Confirm the removal in the prompt that appears.

After you confirm, the subdomain will be disconnected from your account and removed from the list of connected hosts.

What Happens After You Delete a Hubspot Subdomain

Once the host is removed, your domain list will update, and any tools that depended on that subdomain will no longer serve content on those URLs.

Content and Tracking After Removal

• Pages that were published on the host will not load on the old address.
• Page performance data collected before the deletion remains in your analytics, but new visits to those URLs will stop.
• Tracking cookies and analytics continue to function on other connected domains.

DNS and Hosting Considerations Outside Hubspot

Deleting the host from settings does not automatically remove its DNS records at your domain registrar. If you want to fully shut down the URL, you should also update or remove related CNAME or A records where your domain is managed.

Consult your domain provider’s documentation if you need help updating DNS once you are finished inside your CRM tools.

Best Practices for Managing Hubspot Domains and Subdomains

To keep your implementation healthy, follow a few best practices whenever you remove or add hosts.

Plan Subdomain Changes in Advance

• Audit which tools use each host before any deletion.
• Document existing URLs for campaigns and shared links.
• Schedule the change for a low‑traffic time if possible.

Maintain Redirects and Visitor Experience

• Set up redirects on an active host for your most important retired URLs.
• Update external links and partner references over time.
• Monitor traffic and errors after the removal to catch issues quickly.
