If you send high email volume and want more control over your email sending reputation, you can connect a dedicated IP address to send your emails.

After purchasing the dedicated IP address add-on, you can connect the address in your domain settings in HubSpot:

  • In your HubSpot account, click the settings icon settings in the main navigation bar.
  • In the left sidebar menu, navigate to Website > Domains & URLs.
  • Click Connect a domain.
  • In the dialog box, select Dedicated IP, then click Connect.
  • Under Email address, enter an email address that you use to send marketing emails, then click Next.
  • Review the two domains that you'll be setting up:
    • Email sending domain: this domain will be shown in the From address field of your email. This is the domain that your email recipients will see in their inbox.
    • Dedicated IP sending domain: this subdomain will be used as the mailed-by or return-path domain in the email header for marketing and transactional sends. The subdomain is necessary for the delivery of your emails, but isn't usually visible to your email recipients.
  • Configure and verify your hosting settings with your DNS provider:
    • In a separate tab, log in to your DNS provider. Then select the I'm logged in checkbox in HubSpot.
    • In the main navigation menu of your DNS provider, go to DNS > DNS settings. If you're not sure where to locate your DNS settings, reference the steps below for general instructions, or reach out directly to your DNS provider. If you're uncomfortable making these changes yourself, send this article to your IT team. When you're in your DNS settings, select the I'm there checkbox in HubSpot.
    • In the Update your DNS records section in HubSpot, click Copy next to the value in the Host (Name) column and paste it into the corresponding field in your DNS provider account. Then click Copy next to the value in the Value column and paste it into the corresponding field:
      • A record: associates your dedicated IP address with your domain.
      • MX record: processes bounces, spam reports, and unsubscribes to ensure the associated analytics will display in your HubSpot account after you send an email. The MX record priority must be set to 0 in your DNS hosting provider. Some DNS providers have a separate numeric field for Priority and you may have to enter the record value and numeric fields separately.
      • TXT record: sets up SPF authentication. A Sender Policy Framework (SPF) is used by your recipients' email servers to verify the identity of the sender.
      • CNAME records: these records grant HubSpot permission to send emails on your behalf by connecting an email sending domain for DKIM (Domain Keys Identified Mail) email authentication.

Please note: some providers, such as Network Solutions or GoDaddy, will add your brand domain and top-level domain to the end of these DNS records automatically. For example, if you enter {hsdomainkey}, a provider may change that value to {hsdomainkey}, which will result in a DNS error. Instead, copy the value but remove the extra when pasting it into the corresponding field in your DNS provider account.


  • When you're done updating the values in your DNS provider, select the I'm done checkbox in HubSpot.


  • If your DNS records are set up correctly, you'll see a Verified message letting you know your email sending domain is verified. This can take up to 24 hours to take effect everywhere in the world. Once you see the Verified message, click Done.
  • If your DNS records still need to be set up or are still processing, you'll see a Record invalid error displayed to the right of one or all of your records. Click check them again to see if the changes have propagated.

After your DNS setup is complete, an automatic warm up process will begin that will help build a reputation on the IP address by slowly moving traffic from the shared HubSpot IPs to the dedicated IP.

Please note: if you're using a DNS provider that doesn't support the records above, or you don't have access to your domain's DNS settings, the HubSpot Deliverability team can set up your IP on a subdomain instead. You'll still be able to use your own email sending domain in the from address of your emails. To find out more, reply to the Start your HubSpot dedicated IP setup email you received after purchasing the dedicated IP add-on and the Deliverability Operations team will assist you.
