Verify marketing email addresses and domains in Hubspot

Before you send any marketing email from Hubspot, you must verify the email address and domain that will appear in the From field. Proper verification helps reduce deliverability problems, prevents spoofing, and ensures your messages are authenticated by major email providers.

This guide walks you through the exact steps to verify a single email address, add and verify a new domain, and manage verification status inside your account.

Why verifying your Hubspot email domain matters

When you send campaigns, mailbox providers check whether the sending information is legitimate and authenticated. If your domain and From address are not verified, your marketing emails may:

Fail authentication checks like SPF and DKIM
Land in spam or promotions folders more often
Show warnings to recipients about possible spoofing
Be blocked by stricter corporate filters

Verifying your email address and domain in your Hubspot settings confirms that you own them and that they can safely be used for marketing communications.

How Hubspot handles marketing From addresses

In your email tool, each marketing message needs a valid From address. Hubspot lets you configure default From settings and also add custom From addresses per email. Verification ensures those From values are authorized to send.

There are two key concepts you should understand:

Email address verification – proves you control the specific mailbox you want to use in the From field.
Domain verification – proves you control the domain portion (for example, example.com) used in that address.

Often, you will use both features together for best results.

Verify a single email address in Hubspot

If you want to send from an individual mailbox, such as marketing@example.com, your first step is to verify that address directly inside Hubspot.

Steps to verify a new From address

Log in to your account and go to the Marketing Email tool.
Create a new email or open an existing draft.
In the email editor, locate the From address field.
Click the dropdown and choose to Add or Manage From addresses.
Enter the full email address you want to use as the sender.
Hubspot sends a verification email to that address containing a confirmation link.
Open the verification email in your inbox and click the link to confirm ownership.

After you confirm, the address appears as verified and can be used safely as a From option in future campaigns.

Troubleshooting address verification issues

If you do not receive the verification email:

Check the inbox and spam folder for the mailbox you entered.
Confirm that the address was typed correctly in the From settings.
Ask your IT team to review any email security filters that might block automated messages.
Resend the verification from the address management window.

If the link in the verification message has expired, go back to the settings area in Hubspot and trigger another verification email.

Verify your sending domain in Hubspot

Beyond a single mailbox, you should verify the full domain you plan to use for sending. Domain verification improves overall deliverability and ensures that all addresses on that domain can be authenticated properly.

Open the Hubspot domain settings

In your account, click the settings icon in the main navigation.
In the left sidebar menu, navigate to the section for domains.
Look for an option to manage email sending domains or similar domain tools.

From this area, you can start the wizard that adds a new domain for email sending.

Add a new email sending domain

Click the option to Connect or Add a new domain.
Choose the type dedicated to email sending if multiple choices are offered.
Enter the root domain you want to use, for example example.com.
Continue to the next step to generate authentication records.

Hubspot will display a set of DNS records you need to add with your DNS hosting provider.

Configure DNS records for domain verification

To verify your domain, you must update the DNS zone with specific values supplied by the platform. Typical records include:

SPF (TXT record) – authorizes the platform to send on behalf of your domain.
DKIM (CNAME or TXT records) – enables cryptographic signing of messages.
Additional TXT or CNAME records – used strictly for domain verification.

Copy each record exactly as shown in Hubspot, including host name and value, and paste them into your DNS provider’s interface. Save your changes before returning to the verification screen.

Complete the domain verification in Hubspot

After updating DNS, go back to the domain wizard.
Click the button to Verify or Check records.
Hubspot queries your DNS to confirm the records exist and match.

DNS changes can take some time to propagate. If verification fails at first:

Wait at least 15–30 minutes, then try again.
Confirm that each host name and record value in DNS matches the instructions exactly.
Ensure there are no duplicate or conflicting SPF records for your domain.

Once verification succeeds, your domain is enabled for authenticated sending.

Choose the best verified From options in Hubspot

After you have verified both addresses and domains, configure your defaults so users send from the most trustworthy options.

Set default From address and name

Open the global marketing email settings.
Locate the section for default From name and From address.
Pick a verified address based on the domain you have already validated.
Set a clear From name, such as your company or brand name.

Using a consistent and verified identity helps subscribers recognize your messages and trust your campaigns.

Use domain-aligned addresses for better deliverability

Whenever possible, configure From addresses that fully align with the verified domain. For example:

Verified domain: example.com
Recommended From address: newsletter@example.com or marketing@example.com

Avoid using free webmail addresses for marketing sends. Domain-aligned mailboxes make full use of the authentication configuration you completed in your Hubspot account.

Maintain and monitor your Hubspot email configuration

Verification is not a one-time task. You should periodically review your settings and authentication status to maintain strong deliverability.

Review verified domains and addresses

Regularly check the domain management area for any warnings or errors.
Remove old or unused email addresses that should no longer send campaigns.
Confirm that new team members only use verified From addresses for broadcasts.

Update DNS when your infrastructure changes

If your company moves DNS hosting, changes mail servers, or adds new tools, your existing authentication records might need updates. When that happens:

Compare the SPF and DKIM records in DNS with the latest instructions from Hubspot.
Recreate or adjust records after migrations to ensure they stay active.
Re-run the verification checks if you suspect a configuration issue.
