CAN-SPAM

Controlling the Assault of Non-Solicited Pornography And Marketing Act of 2003 (15 USC 7701-7713)

Legally Required Featured Framework

Federal law regulating commercial email by setting standards for commercial messages, requiring opt-out mechanisms, and prohibiting false/misleading headers and deceptive subject lines

Executive Summary

The Controlling the Assault of Non-Solicited Pornography And Marketing Act (CAN-SPAM) establishes requirements for commercial email messages. CAN-SPAM applies to commercial electronic mail messages with primary purpose of commercial advertisement or promotion. Seven core requirements: (1) Don't use false/misleading header information, (2) Don't use deceptive subject lines, (3) Identify message as advertisement, (4) Include valid physical postal address, (5) Provide opt-out mechanism, (6) Honor opt-outs within 10 business days, (7) Monitor third-party email vendors. Primary purpose test determines applicability: commercial content = CAN-SPAM applies; transactional/relationship content = exempt. Opt-out must be functional for 30+ days after sending. Criminal penalties for willful violations: up to $250,000 (individuals)/$500,000 (organizations) and 5 years imprisonment. Civil penalties up to $53,088 per violation (2025 inflation-adjusted). FTC enforcement and State AG concurrent authority. Notable cases: Verkada ($2.95M largest penalty), Massachusetts Commonwealth v. Kuvayev ($37M).

FTC Implementing Regulations

16 CFR Part 316 - CAN-SPAM Rule

Sec. 316.1 - Definitions

  • Enhanced definitions for "sender," "initiator," "procurer"

  • "Person" includes corporations, partnerships, associations


Sec. 316.2 - Prohibition on sale or other transfer of email addresses
  • May not sell/transfer email addresses of persons who opted out

  • May transfer for compliance purposes only


Sec. 316.3 - Primary purpose
Three-part test for determining primary purpose:
  1. Transactional/Relationship Only: If message contains only transactional/relationship content = transactional message (exempt)

  2. Commercial Only: If message contains only commercial content = commercial message (CAN-SPAM applies)

  3. Both Commercial and Transactional: If message contains both:

- Subject line test: If subject line suggests commercial content = commercial message
- Transactional/relationship content placement test: If transactional content appears at beginning = transactional message; if commercial content at beginning = commercial message
- Proportion test: If commercial content predominates by volume = commercial message

Sec. 316.4 - Requirement to place warning labels on commercial electronic mail that contains sexually oriented material

  • Subject line must begin with "SEXUALLY-EXPLICIT: "

  • Electronic mail must contain warning label in front of actual sexually oriented material

  • Warning label requirements (minimum font size, color contrast, etc.)


Sec. 316.5 - Prohibition on charging fee to opt out
  • May not require fee, provide information other than email address, or make recipient take steps other than sending reply email or visiting single internet web page



Who is Covered by CAN-SPAM?

Covered Entities

Any Person Sending Commercial Electronic Mail Messages:

  • Commercial Senders: Businesses sending emails with primary purpose of commercial advertisement/promotion

  • Initiators: Persons who originate commercial email (not just transmit on behalf of others)

  • Procurers: Persons who procure origination of commercial email (e.g., hiring marketing agency)


Primary Purpose Test: Determines if email is "commercial" and subject to CAN-SPAM:

Example Scenarios:

  1. Email advertising product sale = Commercial message (CAN-SPAM applies)

  2. Email confirming online purchase = Transactional message (exempt)

  3. Email updating account status = Relationship message (exempt)

  4. Email with both product ad and order confirmation:

- If subject line is "Great deals on shoes!" = Commercial message (CAN-SPAM applies)
- If subject line is "Your order confirmation" and transactional content appears first = Transactional message (exempt)
- If commercial content predominates by volume = Commercial message (CAN-SPAM applies)

Exemptions

CAN-SPAM Does NOT Apply To:

  • Transactional or Relationship Messages:

- Order/purchase confirmations
- Warranty information
- Product recall notices
- Account balance statements
- Employment relationship information
- Delivery of product/service as part of subscription
- Updates to terms of service or privacy policy
- Safety or security notifications

  • Primary Purpose is Transactional: If email's primary purpose is transactional/relationship content, CAN-SPAM does not apply EVEN IF email also contains commercial content (as long as commercial is not primary purpose)


  • Email Between Businesses (NOT exempt): CAN-SPAM applies to B2B commercial email (unlike telephone spam laws that exempt B2B)


  • Political Campaign Messages: Emails promoting candidates for political office (exempt per FEC regulations)


  • Non-Profit Fundraising: Emails soliciting donations to tax-exempt non-profits (exempt if primary purpose is fundraising, not commercial promotion)


Key Distinction - Transactional vs. Commercial:
  • Transactional: "Your order #12345 has shipped" = Exempt

  • Commercial: "Order #12345 shipped + buy more items!" = If commercial content predominates = CAN-SPAM applies

  • Safe Practice: Keep transactional emails purely transactional; send separate commercial emails that comply with CAN-SPAM



Seven Core CAN-SPAM Requirements

1. Don't Use False or Misleading Header Information

Requirement: "From," "To," and routing information (including originating domain name and email address) must be accurate and identify person/business who initiated message.

What This Means:

  • Email address in "From" line must be valid and accurately identify sender

  • Domain name must accurately identify business sending email

  • "Reply-to" address must be functional

  • Routing information (SMTP headers) must not be falsified


Violations:
  • Using fake sender name or email address

  • Spoofing domain names

  • Manipulating SMTP headers to hide true sender

  • Using harvested email addresses in "From" line


Compliant Examples:
  • From: [email protected] (examplecompany.com is actual sender)

  • From: Jane Doe (Jane Doe works for sender)


Non-Compliant Examples:

2. Don't Use Deceptive Subject Lines

Requirement: Subject line must accurately reflect content of message and not be materially false or misleading.

What This Means:

  • Subject line must give recipient accurate idea of what email is about

  • Cannot use bait-and-switch tactics

  • Cannot suggest email is about one topic when actually about different topic


Violations:
  • Subject: "Re: Your recent order" (when recipient never placed order)

  • Subject: "Your account has been suspended" (when no account exists)

  • Subject: "Urgent: Confirm your information" (when email is marketing promotion)

  • Subject: "Invoice #12345" (when email is advertisement)


Compliant Examples:
  • Subject: "Limited time offer on hiking boots" (email advertises hiking boots)

  • Subject: "ExampleCo June Newsletter" (email contains newsletter)

  • Subject: "New product announcement from ExampleCo" (email announces product)


Non-Compliant Examples:
  • Subject: "Your package delivery failed" (email advertises shipping services)

  • Subject: "Account verification required" (email is phishing scam)


FTC Guidance: Subject line is deceptive if it would mislead recipient acting reasonably under the circumstances about central characteristic of message.

3. Identify the Message as an Advertisement

Requirement: Message must be identified clearly and conspicuously as an advertisement or solicitation.

Important Exception: NOT required if recipient has given affirmative consent (opt-in) to receive messages OR message is sent as part of ongoing business relationship.

What This Means:

  • For cold emails (no prior relationship), must clearly indicate email is advertisement

  • Can be satisfied by subject line, email header, or beginning of message body

  • Must be clear and conspicuous (not hidden in fine print)


When Identification Required:
  • Cold email to purchased email list

  • First marketing email to new prospect

  • Email to person who has not opted in


When Identification NOT Required:
  • Email to customer who previously purchased (business relationship)

  • Email to subscriber who opted in

  • Follow-up email in ongoing conversation


Compliant Examples:
  • "Advertisement: ExampleCo New Product Line"

  • Email begins: "This is a commercial advertisement from ExampleCo"

  • Subject line includes "[Advertisement]" or "[Promotional]"


FTC Guidance: While no specific format required, identification must be clear enough that recipient acting reasonably would understand message is advertisement.

4. Tell Recipients Where You're Located

Requirement: Message must include valid physical postal address.

What This Means:

  • Must include current street address, P.O. Box registered with USPS, or private mailbox registered with commercial mail receiving agency

  • Must be address where sender can receive postal mail

  • "ExampleCo, PMB 123, 456 Business Blvd, Somerville, MA 02144"


Non-Compliant Examples:
  • No address listed

  • Address of third-party marketing firm (if not actual sender)

  • Invalid or non-existent address

  • Foreign address if U.S.-based sender


Address Placement: Must appear in email; typically in footer, but can be anywhere as long as clear and conspicuous.

5. Tell Recipients How to Opt Out of Receiving Future Emails

Requirement: Message must include clear and conspicuous explanation of how recipient can opt out of future emails.

Opt-Out Mechanism Requirements:

  • Functional for 30+ Days: Opt-out mechanism must work for at least 30 days after message sent

  • Easy to Use: Must allow recipient to opt out without providing information beyond email address

  • No Fee: Cannot charge fee to opt out

  • Single Step: Recipient should be able to opt out with single click or single email reply

  • Clear Instructions: Recipient must understand how to opt out


Compliant Examples:

  • Unsubscribe link leading to simple one-page form requiring only confirmation (no additional data entry)


Non-Compliant Examples:
  • "Email us at [email protected] and provide your full name, email address, mailing address, and phone number" (requires excessive information)

  • "Login to your account, navigate to Settings > Email Preferences > Marketing Communications, and uncheck all boxes" (too many steps)

  • Unsubscribe link that requires creating account or providing additional personal information

  • Unsubscribe mechanism that only works for 15 days (must work 30+ days)


Menu-Based Opt-Out: Can provide "menu" allowing recipient to opt out of certain types of messages while continuing to receive others (e.g., "unsubscribe from weekly newsletter but keep receiving product updates"). BUT must also provide option to opt out of ALL commercial messages.

6. Honor Opt-Out Requests Promptly

Requirement: Must honor opt-out request within 10 business days.

What This Means:

  • Stop sending commercial email to recipient within 10 business days of opt-out

  • Cannot sell or transfer email addresses of people who opted out (except to company you hire to comply with CAN-SPAM)

  • Opt-out request is effective for ALL commercial messages from sender (cannot require separate opt-outs for different message types)


10 Business Day Compliance Timeline:
  • Day 1: Recipient clicks "unsubscribe" link

  • Day 10 (business days): Last permissible day to send commercial email to that recipient

  • After Day 10: Sending additional commercial email = violation


Transfer Prohibition: Cannot sell, lease, exchange, or transfer email addresses of people who opted out. Exception: Can transfer to third-party vendor hired to help comply with CAN-SPAM (e.g., email service provider managing unsubscribe list).

Suppression List: Must maintain suppression list (unsubscribe list) and check against it before sending commercial emails.

7. Monitor What Others Are Doing on Your Behalf

Requirement: If you hire another company to handle email marketing, both you and that company may be held legally responsible for CAN-SPAM compliance.

What This Means:

  • Joint Liability: Both the company whose product/service is promoted AND the company that sends email can be liable

  • "Promoted Person" Liability: Business whose product/service is promoted can be liable even if didn't send email directly

  • Due Diligence Required: Businesses must monitor third-party email vendors for compliance


Affirmative Defense for Promoted Businesses (15 USC 7705):
Business promoted in email can avoid liability if proves:
  1. Business did not authorize use of false/misleading transmission information, AND

  2. Business exercised reasonable care to select responsible email vendor, AND

  3. Business did not know and could not reasonably have known email would contain violations


Vendor Management Best Practices:
  • Contractually require vendors to comply with CAN-SPAM

  • Review sample emails before campaigns launch

  • Audit vendor practices regularly

  • Maintain documentation of vendor selection process and monitoring

  • Require vendors to indemnify for CAN-SPAM violations

  • Immediately investigate complaints about vendor emails


Example Scenario:
  • ExampleCo hires MarketingAgency to send promotional emails

  • MarketingAgency uses false headers and deceptive subject lines

  • Both ExampleCo AND MarketingAgency can be liable

  • ExampleCo can avoid liability only if proves exercised reasonable care in selecting MarketingAgency and didn't know/couldn't reasonably know of violations



Sexually Explicit Content Requirements

Enhanced Requirements for Adult Content

16 CFR Sec. 316.4 - Warning Labels

If commercial email contains sexually oriented material:

1. Subject Line Warning:

  • Must begin with "SEXUALLY-EXPLICIT: " (exact format with colon and space)

  • Warning must be at very beginning of subject line

  • No other content can precede warning


2. "Brown Paper Wrapper":
  • Email must include warning label immediately visible when email opened

  • Warning label must:

- State message contains sexually oriented material
- Appear at beginning of message (before any images or content)
- Meet minimum formatting requirements (font size, color contrast)
  • Sexually oriented material cannot be visible until recipient scrolls past warning


3. Opt-Out Required:
  • Same opt-out requirements as all CAN-SPAM messages

  • Opt-out mechanism must appear before sexually oriented material (can be on warning label screen)


Violations:
  • Subject line: "Great deals inside!" (should be "SEXUALLY-EXPLICIT: Great deals inside!")

  • Sexually explicit image appears immediately when email opened (no warning label first)

  • Warning label in small, light-colored text (not clear and conspicuous)


Compliant Example:

Subject: SEXUALLY-EXPLICIT: Adult Products Sale

[Email opens to warning screen]

WARNING: This email contains sexually oriented material.

To view this message, scroll down.

[Unsubscribe link]

[Recipient scrolls down to see sexually oriented content]

  • Each email can be separate violation (penalties can accumulate rapidly)


Calculation Example:
  • Company sends 100,000 emails violating CAN-SPAM

  • Theoretical maximum penalty: 100,000 emails × $53,088 = $5.3 BILLION

  • Actual penalties: FTC typically seeks reasonable penalties based on company size, harm, and compliance history


Factors Considered in Penalty Amount:

Industry-Specific Guidance

E-Commerce Retailers

Transactional Emails (Exempt from CAN-SPAM):

  • Order confirmations

  • Shipping notifications

  • Delivery confirmations

  • Product recall notices

  • Warranty information


Commercial Emails (Subject to CAN-SPAM):
  • "Customers who bought X also bought Y" recommendations

  • Weekly sales announcements

  • Abandoned cart reminders (if primary purpose is promoting purchase)

  • New product launches


Best Practices:
  • Keep transactional emails purely transactional (don't add promotional content)

  • Send separate promotional emails that comply with CAN-SPAM

  • Make unsubscribe link prominent in all commercial emails

  • Allow customers to opt out of promotional emails while still receiving order confirmations


SaaS and Technology Companies

Transactional Emails (Exempt):

  • Account creation confirmations

  • Password reset emails

  • Service status notifications

  • Terms of service updates

  • Security alerts


Commercial Emails (Subject to CAN-SPAM):
  • Feature announcement emails promoting upgrades

  • Webinar invitations

  • Case study emails

  • "Upgrade to Pro" promotional emails


Best Practices:
  • Distinguish clearly between service notifications and marketing

  • Provide granular email preferences (product updates vs. marketing vs. critical alerts)

  • Honor opt-outs for marketing while continuing critical security notifications


B2B Service Providers

Common Misconception: "CAN-SPAM doesn't apply to B2B email"
Reality: CAN-SPAM DOES apply to B2B commercial email (unlike TCPA telephone rules which exempt B2B)

Covered B2B Emails:

  • Cold outreach to prospects

  • Newsletter to client contacts

  • Event invitations

  • Product/service announcements


Best Practices:
  • Include unsubscribe option in all B2B commercial emails

  • Honor opt-outs from company contacts (even if sent to generic role address like [email protected])

  • Use CRM to track opt-outs across all contacts at a company


Marketing Agencies

Joint Liability Risk:

  • Marketing agency that sends email on behalf of client = liable

  • Client whose product/service is promoted = also liable

  • Both can be penalized for same violation


Best Practices for Agencies:
  • Contractually require clients to warrant their email lists are compliant

  • Review all email content for CAN-SPAM compliance before sending

  • Maintain independent suppression list

  • Document all compliance procedures

  • Carry errors & omissions insurance covering CAN-SPAM violations


Best Practices for Clients Hiring Agencies:
  • Vet agency's CAN-SPAM compliance procedures before hiring

  • Review sample campaigns before launch

  • Maintain oversight and audit rights

  • Require agency indemnification for violations

  • Document "reasonable care" in selecting agency (affirmative defense)



Related Federal Laws and Frameworks

Telephone Consumer Protection Act (TCPA)

47 USC 227 - TCPA:

  • Regulates telemarketing calls and text messages

  • Requires prior express consent for marketing calls/texts to mobile phones

  • Do-Not-Call registry

  • Restrictions on autodialers and prerecorded messages

  • FCC and FTC enforcement

  • Private right of action ($500-$1,500 per violation)


Key Difference from CAN-SPAM:
  • CAN-SPAM (email): Opt-out regime (can send until recipient opts out)

Conclusion

The CAN-SPAM Act establishes national standards for commercial email, balancing businesses' ability to communicate with consumers while protecting consumers from deceptive and excessive spam. Compliance requires:

Seven Core Steps: Accurate headers, honest subject lines, advertisement identification (if applicable), physical address, opt-out mechanism, honoring opt-outs within 10 days, and vendor monitoring.

Key Penalties: Criminal penalties up to $250,000/$500,000 and 5 years imprisonment; civil penalties up to $53,088 per violation (2025); joint FTC and State AG enforcement authority.

Massachusetts-Specific: Massachusetts AG has concurrent enforcement authority; notable MA cases include Verkada ($2.95M largest penalty) and Kuvayev ($37M); MA businesses must comply with both federal CAN-SPAM and MA state anti-spam law.

Best Practices: Maintain suppression list, test unsubscribe links regularly, keep transactional emails separate from commercial emails, train staff, monitor third-party vendors, document compliance procedures, and implement email compliance program.

Organizations sending commercial email must implement robust compliance programs, train staff, monitor vendors, and honor consumer opt-out preferences to avoid significant penalties and protect consumer trust.
