To help prevent your marketing emails from getting caught in spam filters, you can give HubSpot permission to send emails on your behalf by connecting an email sending domain for DKIM (Domain Keys Identified Mail) email authentication. This removes the via HubSpot text that appears in the sender information at the top of your marketing emails. 

If you have any trouble after following the steps below, learn how to troubleshoot your email sending domain.

Please note: you can connect a subdomain, like, as your email sending domain. The subdomain you connect should match the domain in the From email address you're using to send marketing emails in HubSpot. 

  • In your HubSpot account, click the settings icon settings in the main navigation bar.

  • In the left sidebar menu, navigate to Domains & URLs.

  • Click Connect a domain.

  • In the dialog box, select Email Sending, then click Connect.

  • Enter the email address you use to send marketing emails from this domain, then click Next.
  • On the next screen, verify that the email sending domain is correct, then click Next
  • You're ready to set up your hosting with your DNS provider.
    • If you're hosting with GoDaddy, click Authorize with GoDaddy to allow HubSpot to make changes to your records and finish setting up your hosting.
    • If you are not using GoDaddy, or would prefer to make these changes manually, click No, I'll set it up manually, then follow the instructions below:
      • 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.

        Please note: if you're using Network Solutions or NameCheap for hosting, or adding your records to GoDaddy manually, these providers add your brand domain and top level domain to the end of these DNS record automatically. This means that if you enter, it will turn that value to, which will result in a DNS error. Instead, enter hs1._domainkey into the DNS record.

      • When you're done updating the values in your DNS provider, select the Done checkbox in HubSpot. connect-email-sending-domain-update-dns-records
  • 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.
