Email Marketing and the Law: What Small Business Owners Need to Know About CAN-SPAM

If you send marketing emails to your customers, you are subject to a federal law called the CAN-SPAM Act. Most small business owners have never read it and many have never even heard of it. That is a problem, because the penalties for violations are steep and the rules are not always what people assume.

This law is not complicated law once you understand what it actually requires. Many business owners, however, get tripped up on the same few points again and again, so let's walk through what you need to know.

What CAN-SPAM Covers

CAN-SPAM applies to any commercial email, meaning any message whose primary purpose is advertising a product or service. Think newsletters with promotional content, sales announcements, and anything encouraging a purchase. It does not matter whether you are a one person LLC or a large corporation. If you send commercial email, the law applies to you.

The law is enforced by the Federal Trade Commission, and violations can result in penalties per email, not per campaign. Sending one email to a list of a few thousand people without proper compliance can add up fast.

The Core Rules

The requirements are more straightforward than people expect. Your header information, meaning the "from," "to," and routing information, has to be accurate and identify the business sending the message. Deceptive subject lines are prohibited, so the subject has to reflect what is actually in the email.

Every commercial email needs to tell recipients where you are located, either your street address or a registered post office box. You also need to include a clear and conspicuous way to opt out of future emails, and that opt out mechanism has to keep working for at least thirty days after you send the message.

Once someone opts out, you have ten business days to honor that request. You cannot charge a fee, require them to give more information than their email address, or make them jump through steps beyond a simple unsubscribe process.

Common Mistakes

• CAN-SPAM does not require opt in consent the way some international privacy laws do, but it does require that you honor every opt out request going forward.  Do not assume that if a customer bought something from you – or you received someone’s card at a networking event – that you are automatically permitted to send unlimited marketing emails forever.

•  Many business owners lose track of who has unsubscribed when they switch email platforms or merge customer lists.

•  Another common mistake is using a personal email account to send bulk marketing messages without any unsubscribe link at all. This usually happens when a business owner is just getting started and has not thought about their email marketing as something that needs a compliance process.

  
  

I also see confusion about transactional emails. A receipt, a shipping confirmation, or a response to a customer service inquiry is not considered a commercial email under CAN-SPAM, even if it contains some promotional content. The primary purpose test matters here, so if you are unsure whether a message counts as commercial, it is worth thinking through the primary purpose before you hit send

Using a Marketing Platform Can Help With Compliance

Most email marketing platforms build compliance features into their tools, including automatic unsubscribe links and physical address fields. Using one of these platforms is a smart move for a small business, but it does not mean you are automatically compliant. You are still responsible for how the platform is configured and for making sure your subject lines and sender information are accurate.

If you are managing a customer list that spans multiple platforms, or if you inherited a list through a business acquisition, it is worth doing a review to confirm that opt out requests were carried over correctly. This is exactly the kind of detail that gets missed during a transition.

Email marketing is one of the most effective tools a small business has, and staying compliant with CAN-SPAM is not difficult once you understand the requirements. Taking a few minutes to review your current email practices now can save you a real headache later.
