In your HubSpot account, click the settings iconsettings 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.
Dedicated sending IP: this domain will be used as the Mailed by domain in the email header for your dedicated IP, and will not be easily visible to your email recipients from their inbox.
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 are 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.
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.
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.
