How to Perform a CAN-SPAM Audit to Protect Your Email Reputation and Avoid Fines

Auditing CAN-SPAM isn’t just about ticking boxes. It’s about protecting your email reputation, your deliverability, and your business. The CAN-SPAM Act sets clear rules for commercial email: no deceptive headers, no misleading subject lines, clear identification as an ad, a valid physical address, and an opt-out mechanism that works fast. If you miss any of these, each message you send could carry a fine that stacks up quickly.

An effective audit starts with looking at every email you send, not just blasts from marketing tools. Transactional messages, automated workflows, and even individual outreach can all fall under CAN-SPAM. Each message needs clear sender identification, accurate routing information, and subject lines that match the content.

Next is the unsubscribe process. It must be easy to find, functional in a single step, and honored within 10 business days. Remove friction. No logins. No forms asking why. Just a clean confirmation that the person is off your list.

Content review is the third pillar. Avoid misleading language. Be transparent about who you are and why you’re contacting the recipient. If you include promotional content in something labeled as a “receipt” or “account update,” you may cross into prohibited territory.

Compliance also means verifying technical setup. This includes making sure your sending domains, DKIM signatures, and SPF records match the email headers and routing details to prevent spam filters from flagging your messages as suspicious. Doing these checks during an audit is critical.

Store your audit results. Document the date, the findings, and the fixes. This record can reduce risk if a complaint turns into a legal inquiry. Repeat the process regularly, especially after changing automation platforms, templates, or sending infrastructure.

The longer you put off an audit, the more vulnerable your program becomes. The law is clear, but the responsibility to meet it is on you. A missed detail today can turn into a compliance nightmare tomorrow.
