Understand Hubspot Domain Subscription Limits

When you manage multiple brands or websites in Hubspot, understanding how domain subscription limits work is essential to avoid connection errors, hosting problems, and email sending issues.

This guide explains the different domain types, how limits are applied to each Hubspot subscription, and how to plan your domain strategy without running into unexpected caps.

Key Hubspot Domain Concepts

Before looking at subscription limits, you need to understand how Hubspot classifies domains. Each type of domain has a different purpose and may count differently toward your account limits.

Primary, Secondary, and Redirected Domains

For website content, Hubspot lets you set several categories of domains:

• Primary domains: main live domains where content is hosted.
• Secondary domains: additional live domains for separate brands or regions.
• Redirected domains: domains that forward traffic to a primary or secondary domain.

These domain types are specifically tracked against your Hubspot subscription domain limits. The more sites or brands you operate, the more important it becomes to manage these slots carefully.

Domain Types in Hubspot Tools

Hubspot uses domains across several tools. The key domain types include:

• Website domains for pages, blogs, and knowledge base content.
• Email sending domains used to authenticate marketing and transactional emails.
• Brand domains representing the main root domains you connect.

Not every domain connection counts toward the same limit. Website hosting, email authentication, and brand management each play different roles in the overall Hubspot domain model.

How Hubspot Domain Subscription Limits Work

Every paid tier includes defined caps on how many domains you can connect and host. These limits protect performance and help you match Hubspot to your business scale.

Brand Domain Limits in Hubspot

A brand domain is the base domain for your business, such as example.com. Subdomains like www.example.com or info.example.com are tied to the same brand domain. Depending on your subscription, Hubspot restricts how many brand domains you can use for hosting and sending emails.

Typical constraints include:

• A default number of brand domains included with a subscription.
• The ability to purchase additional brand domains as add-ons.
• Different brand domain limits between marketing, CMS, and other Hubs.

Because the brand domain is the root of all related subdomains, each new brand you add can consume a valuable slot in your Hubspot account.

Website Domain Limits for Hosted Content

For hosting website pages, blogs, and knowledge base content, Hubspot counts each connected domain used to serve live content:

• Primary domains for main sites.
• Secondary domains for additional sites or brands.
• Redirected domains that funnel visitors into active sites.

If you reach your website domain limit, you will not be able to add more primary or secondary domains until you remove one or upgrade your subscription. Redirected domains can also affect how many total entries are available, depending on your plan.

Email Sending Domain Limits in Hubspot

Email sending domains are used for authentication and improving deliverability. In Hubspot, you verify a domain so that marketing emails, transactional emails, and one-to-one emails can send securely from addresses under that domain.

Subscription rules for email sending domains generally include:

• A standard number of email sending domains you can verify.
• Shared use of brand domains between email and website hosting.
• Requirements to authenticate DNS records for each email domain.

If you manage multiple brands or regional email strategies, you must track how many sending domains are active to avoid hitting your Hubspot limits.

Checking Your Current Hubspot Domain Limits

To manage domain capacity, you need to know your current limits and usage. Hubspot provides this information in your settings area.

Steps to View Domain Usage

1. Log in to your Hubspot account as a user with appropriate permissions.
2. Navigate to Settings from the main navigation.
3. Go to Website and then select Domains & URLs.
4. Review the list of connected domains, including primary, secondary, and redirected entries.
5. Check the indicators showing how many domains are in use versus the total allowed by your subscription.

This view helps you quickly see whether you are close to your Hubspot domain cap and which domains are consuming your slots.

Managing Domains Within Hubspot Limits

Staying within your allowed quotas requires planning. Use a structured approach when you add, consolidate, or remove domains in Hubspot.

Plan Your Brand and Website Structure

Before connecting a new domain, map out how it supports your overall strategy:

• Identify the main brand domains your business truly needs.
• Consider subdomains instead of separate domains where possible.
• Consolidate legacy or low-traffic sites into fewer core domains.

This planning helps you use your Hubspot domain slots more efficiently and reduces maintenance overhead.

Optimize Redirected Domains

Redirects are powerful but can consume capacity if not managed carefully. To stay within your Hubspot limits:

• Eliminate unused or outdated redirected domains.
• Use DNS-level redirects outside Hubspot when appropriate.
• Group similar redirects under a single domain when feasible.

By tightening your redirect strategy, you free up room for primary or secondary domains that deliver more value.

Align Email and Website Domains in Hubspot

Because brand and email sending domains are related, coordinate decisions between your web and email teams:

• Use the same brand domain for both site hosting and email when possible.
• Limit unique email sending domains to those required for compliance or branding.
• Document which Hubspot tools rely on each domain to avoid accidental disruptions.

This alignment prevents scenarios where you exhaust brand domains for email while still needing capacity for new websites or landing page projects.

When to Upgrade Your Hubspot Subscription

If your business outgrows the included domain limits, upgrading may be necessary. Common signs you need more capacity include:

• Frequent errors when trying to add new primary or secondary domains.
• New brands or acquisitions that require their own hosted sites.
• Complex international or multi-division structures needing distinct domains.

To evaluate your options, compare your existing plan’s domain caps with higher tiers or brand domain add-ons documented in the official Hubspot knowledge base: View Hubspot domain subscription limits.
