HubSpot Guide to CAN-SPAM Compliance

Email marketers using HubSpot must understand CAN-SPAM rules to keep campaigns compliant, protect their brand, and avoid costly legal penalties.

The CAN-SPAM Act sets the legal standards for commercial email in the United States. If you send promotional emails to U.S. recipients, these rules apply to you, whether you use HubSpot or another platform.

What Is CAN-SPAM and Why It Matters to HubSpot Users

The CAN-SPAM Act of 2003 is a U.S. law that governs commercial email. It gives recipients the right to stop receiving certain messages and defines clear requirements for senders.

Violations can be expensive. Each non-compliant email can trigger a separate fine, so a single campaign sent from HubSpot to a large list could create major risk if basic rules are ignored.

Beyond fines, ignoring CAN-SPAM can damage your sender reputation, lower deliverability, and erode subscriber trust.

Key CAN-SPAM Requirements Every HubSpot Marketer Must Follow

Whether you manage campaigns manually or with HubSpot automation, you must comply with these core requirements:

• Identify the message as an ad when required.
• Use accurate header information.
• Write truthful, non-deceptive subject lines.
• Include your valid physical postal address.
• Explain how recipients can opt out.
• Honor opt-out requests promptly.
• Monitor vendors and partners who send on your behalf.

Truthful Header Information in HubSpot Campaigns

The “From,” “To,” and routing information in your email must accurately identify you or your business.

• Use a real domain you control.
• Match the sender name to your brand or a known team member.
• Avoid misleading or generic addresses that hide your identity.

In any email marketing platform, including HubSpot, make sure your default sender settings are honest and consistent with your brand.

Honest Subject Lines in HubSpot Emails

Your subject line must accurately reflect the content of the message.

• Do not suggest a reply or ongoing conversation if none exists.
• Avoid clickbait that promises something the email does not deliver.
• Be clear about offers, discounts, and deadlines.

If you run A/B tests in HubSpot, ensure every tested subject line still truthfully represents the email content.

Identifying Ads and Including a Physical Address

You must clearly and conspicuously disclose when a message is an advertisement, unless there is a prior relationship or exemption that applies under the law.

Additionally, CAN-SPAM requires that every commercial email include a valid physical postal address, such as:

• Your current street address.
• A U.S. Postal Service post office box.
• A private mailbox registered with a commercial mail receiving agency.

Configure your default footer in tools like HubSpot to automatically display your legal business address in all commercial emails.

Opt-Out and Unsubscribe Requirements for HubSpot Users

Every commercial email must give recipients a clear way to opt out of future messages from you.

• Make the unsubscribe option easy to find and read.
• Do not require a login or extra steps beyond what the law permits.
• Offer simple list-level or global opt-out when possible.

CAN-SPAM requires that you honor unsubscribe requests within 10 business days and that your opt-out mechanism remains active for at least 30 days after sending.

Practical HubSpot Checklist for CAN-SPAM

Use this simple checklist as you design and send any campaign from a marketing platform like HubSpot or another service:

HubSpot Email Setup Checklist

1. Confirm that the “From” name and email address clearly identify your business.
2. Write a subject line that accurately describes the content or offer.
3. Verify that your footer displays your current physical postal address.
4. Ensure there is a visible unsubscribe link in the footer.
5. Test the unsubscribe link to confirm it works correctly.
6. Check that your email content matches what you promised in the subject line.
7. Document how you will process and store unsubscribe requests.

HubSpot List and Opt-Out Management

Good list hygiene supports both CAN-SPAM compliance and long-term email performance.

• Remove or suppress addresses that have opted out.
• Stop sending to addresses that repeatedly bounce.
• Avoid purchasing lists that may include people who have not consented to hear from you.
• Respect preferences when contacts limit certain categories of messages.

Working With Agencies and Partners While Using HubSpot

If you outsource email marketing or share your data with a partner, you are still responsible for what gets sent in your name.

• Review and approve all email templates and campaigns.
• Require compliance with CAN-SPAM in your contracts.
• Monitor performance and complaint rates.
• Retain access to unsubscribe and suppression lists.

Whether a third party uses its own system or a platform like HubSpot, you and the vendor can both be held legally accountable for violations.

Legal Risks of Ignoring CAN-SPAM in HubSpot Campaigns

Every non-compliant message can carry a significant fine. For a growing list, that risk scales quickly.

Beyond potential penalties, failing to follow CAN-SPAM standards can:

• Increase spam complaints and spam folder placement.
• Damage your domain and IP reputation.
• Reduce open rates, clicks, and revenue from email.
• Weaken long-term trust with subscribers and customers.

Compliant practices protect both your business and your subscribers.
