A common misconception holds that Minnesota requires businesses to obtain opt-in consent before sending commercial email, and that the state layers its own detailed rules for postal addresses, opt-out timing, and record retention on top of federal law. That is not how Minnesota law works. Minnesota’s commercial email statute, Minn. Stat. § 325F.694, is an opt-out statute. It does not require consent before sending. Its focus is narrow: it bans false and misleading commercial email, requires an “ADV” label on unsolicited commercial messages, and requires senders to offer a way to opt out.

The detailed operational rules that most marketers think of as email compliance, such as honoring opt-out requests within a set number of days, including a physical mailing address, and identifying a message as an advertisement, come from the federal CAN-SPAM Act, not from Minnesota law. For a Minnesota sender, the practical picture has two layers: a short state statute aimed at falsity and labeling, and the federal CAN-SPAM Act, which supplies the operational requirements that govern most of what a commercial email must contain and do.

Key Takeaways

  • Minnesota’s commercial email statute, Minn. Stat. § 325F.694, is an opt-out statute. It imposes no opt-in consent requirement before sending commercial email.
  • The statute’s core prohibition is falsity. No sender may misrepresent the origin or transmission path of a message or use a false or misleading subject line.
  • Unsolicited commercial email must carry “ADV” as the first characters of the subject line, unless an exception applies, such as recipient consent or an existing business or personal relationship.
  • Senders must give recipients an easy method, such as a valid return email address or toll-free number, to opt out of further unsolicited commercial email.
  • A person injured by a violation can recover statutory damages and, in the court’s discretion, attorney fees, but no class action is allowed under the statute.
  • The federal CAN-SPAM Act supplies the operational rules, including honoring opt-outs within 10 business days, a physical postal address, advertisement identification, and treating address harvesting as an aggravated violation. It also preempts state email statutes except for their falsity and deception provisions.

What Minnesota Law Actually Requires: Section 325F.694

The title of the statute signals its scope. Minn. Stat. § 325F.694 is captioned “False or Misleading Commercial Electronic Mail Messages.” It is a consumer-protection provision aimed at deceptive email, not a comprehensive marketing-consent code.

What Counts as a Commercial Electronic Mail Message

The statute defines a “commercial electronic mail message” as an electronic mail message sent through an Internet service provider’s facilities located in Minnesota, to a Minnesota resident, for promoting real property, goods, or services for sale or lease. That definition sets the statute’s reach. It turns on Minnesota network facilities and Minnesota recipients, and it applies to promotional email rather than purely transactional or relationship messages.

The Core Prohibition: No Falsity or Misrepresentation

The heart of the statute is its ban on deception. Under subdivision 2, no person may initiate the transmission of a commercial electronic mail message that uses a third party’s Internet domain name without permission, that otherwise misrepresents information identifying the point of origin or the transmission path of the message, or that contains false or misleading information in the subject line. This falsity ban is the provision that matters most, because, as explained below, it is the part of the statute that federal law expressly leaves in place.

The “ADV” Label for Unsolicited Commercial Email

Subdivision 3 requires that the subject line of a commercial electronic mail message include “ADV” as the first characters. If the message contains material of a sexual nature that may be viewed only by an individual 18 years of age or older, the subject line must include “ADV-ADULT” as the first characters.

This labeling requirement is aimed at unsolicited email. The statute lists several messages that fall outside the requirement, including a message where the recipient has consented to receive or has solicited email from the sender, a message from an organization communicating exclusively with its members, a message from an entity communicating exclusively with its employees or contractors, and a message where a business or personal relationship exists between the sender and the recipient. The statute defines a “business relationship” as a prior or existing relationship formed on the basis of the recipient’s inquiry, application, purchase, or use of products, information, or services offered by the sender or its affiliate or agent.

The Opt-Out Method

Under subdivision 4, a sender must establish a toll-free telephone number, a valid sender-operated return electronic mail address, or another easy-to-use electronic method that a recipient can use to tell the sender to stop transmitting further unsolicited commercial email. The message itself must inform the recipient of that opt-out method. This is an opt-out duty, and it confirms the statute’s design. A business may send first and must then honor a recipient’s request to stop.

Private Remedies

Subdivision 7 creates a private right of action. A person injured by a violation, other than an electronic mail service provider, may recover the lesser of $25 for each message that violates the falsity ban in subdivision 2, or $35,000 per day. For a violation of the “ADV” labeling requirement in subdivision 3, the recovery is the lesser of $10 for each message, or $25,000 per day. A court may award costs, disbursements, and reasonable attorney fees to a party that recovers damages. Importantly, the statute states that no class action may be brought under it, which meaningfully limits its use as a mass-litigation tool.

This point deserves emphasis because it is widely misunderstood. Minnesota does not require a business to obtain a recipient’s consent before sending commercial email. There is no opt-in mandate, no double opt-in requirement, and no requirement to document consent in the statute.

Consent matters in only one direction under Minnesota law. It is an exception to the “ADV” labeling requirement, not a precondition to sending. If a recipient has consented to or solicited the email, or has an existing business or personal relationship with the sender, the message does not need the “ADV” subject-line label. Consent therefore reduces a labeling obligation. It is not a gate the sender must clear before sending.

The Federal CAN-SPAM Act Supplies the Operational Rules

Most of the rules businesses associate with email compliance are federal. The CAN-SPAM Act, codified at 15 U.S.C. § 7704, sets the operational requirements that apply to a Minnesota sender on top of state law. These are federal rules, not Minnesota-specific ones.

Honor Opt-Out Requests Within 10 Business Days

Every commercial email must include a functioning return address or comparable Internet-based mechanism, clearly and conspicuously displayed, that a recipient can use to ask not to receive future messages, and that mechanism must keep working for at least 30 days after the message is sent. Once a recipient asks to stop, it is unlawful for the sender to send a further commercial message within the scope of that request more than 10 business days after receiving it. This 10-business-day opt-out deadline is a federal rule under section 7704(a), not a Minnesota one.

Identify the Advertisement and Include a Physical Address

Under section 7704(a)(5), a commercial email must give the recipient clear and conspicuous identification that the message is an advertisement or solicitation, clear and conspicuous notice of the opportunity to opt out, and a valid physical postal address of the sender. The advertisement-identification requirement does not apply where the recipient has given prior affirmative consent, but the opt-out notice and the physical postal address are required regardless.

No False Headers or Deceptive Subject Lines

CAN-SPAM independently prohibits materially false or materially misleading header information and deceptive subject headings. This federal falsity ban runs parallel to Minnesota’s subdivision 2, which is why the two layers reinforce each other on the question of deception.

Address Harvesting Is an Aggravated Violation

CAN-SPAM treats certain practices as aggravated violations under section 7704(b). These include harvesting email addresses by automated means from a website or online service that stated it would not transfer addresses, generating addresses through a dictionary attack that combines names, letters, or numbers into permutations, and using scripts to register multiple accounts for sending. A Minnesota business that buys or scrapes address lists should treat these federal prohibitions as a hard limit.

How State and Federal Law Fit Together: Preemption

Because both Minnesota and the federal government regulate commercial email, the question is how the two fit together. CAN-SPAM answers it directly. Under 15 U.S.C. § 7707(b)(1), the federal Act “supersedes any statute, regulation, or rule of a State or political subdivision of a State that expressly regulates the use of electronic mail to send commercial messages, except to the extent that any such statute, regulation, or rule prohibits falsity or deception in any portion of a commercial electronic mail message or information attached thereto.”

The result is a clean division. Minnesota’s falsity and deception provisions, chiefly the subdivision 2 ban on misrepresenting a message’s origin, transmission path, or subject line, fall within that express exception and continue to apply alongside CAN-SPAM. Minnesota’s remaining provisions regulate the use of email to send commercial messages without prohibiting falsity or deception, so they fall within the scope of what section 7707(b)(1) supersedes, which places the operational rules of commercial email under the federal Act. Section 7707(b) also preserves state laws that are not specific to email, such as general trespass, contract, tort, fraud, and computer-crime law. Minnesota’s statute anticipates this hierarchy. Subdivision 8 provides that if federal law regulating commercial email is enacted without fully preempting state law, that federal law supersedes any conflicting provisions of the state statute.

For a Minnesota business, the takeaway is straightforward. Do not send false or deceptive commercial email, which both Minnesota and federal law prohibit, and follow CAN-SPAM’s operational requirements, which supply the detailed rules.

Practical Compliance Guidance

  • Do not treat Minnesota as an opt-in state. Minnesota does not require consent before sending commercial email. A compliant program is built around honoring opt-outs, not around gating sends behind consent.
  • Never falsify routing information or subject lines. This is the area where both Minnesota and federal law impose direct liability, and it is where Minnesota’s statutory damages and attorney-fee exposure live.
  • Label unsolicited commercial email correctly. Where the Minnesota “ADV” rule applies and no exception is available, the subject line should begin with “ADV,” or with “ADV-ADULT” for adult material.
  • Follow CAN-SPAM’s operational checklist on every send. Include a working opt-out mechanism, honor opt-out requests within 10 business days, identify the message as an advertisement unless the recipient consented, and include a valid physical postal address.
  • Do not harvest or scrape email addresses. Automated harvesting and dictionary attacks are aggravated violations under federal law.
  • Track the exceptions, but do not over-rely on them. Consent and an existing business or personal relationship can remove the Minnesota “ADV” labeling obligation and the federal advertisement-identification obligation, but they do not eliminate the duty to avoid deception or to honor opt-out requests.

Frequently Asked Questions

No. Minn. Stat. § 325F.694 is an opt-out statute. It does not require a business to obtain consent before sending commercial email. Consent is relevant only as an exception to the statute’s “ADV” subject-line labeling requirement, not as a precondition to sending.

What is the “ADV” label, and when is it required?

Minnesota requires the subject line of an unsolicited commercial email to begin with “ADV,” or with “ADV-ADULT” when the message contains adult material. The requirement does not apply when an exception is present, such as the recipient’s consent or solicitation, communications limited to an organization’s members or an entity’s employees and contractors, or an existing business or personal relationship between the sender and the recipient.

Does the 10-business-day opt-out deadline come from Minnesota law?

No. The requirement to honor an opt-out request within 10 business days is a federal rule under the CAN-SPAM Act, 15 U.S.C. § 7704(a). Minnesota law requires a sender to offer an opt-out method but does not set that deadline. A Minnesota sender must still follow the federal deadline.

Can a plaintiff bring a class action under the Minnesota statute?

No. Subdivision 7 of the statute states that no class action may be brought under it. An injured person may recover statutory damages and, in the court’s discretion, costs and reasonable attorney fees, but only on an individual basis.

What must a commercial email include?

Under the federal CAN-SPAM Act, a commercial email must include a clear and conspicuous opt-out mechanism, notice of the opportunity to opt out, identification that the message is an advertisement unless the recipient has consented, and a valid physical postal address. Under Minnesota law, an unsolicited commercial message must also carry the “ADV” subject-line label unless an exception applies, and no message may misrepresent its origin, transmission path, or subject line.
