How to use the CAN-SPAM Email Footer Generator

Enter your company name, physical mailing address (required by law in US and Canada), unsubscribe URL, optional preference center URL, and a brief “why are they getting this” reminder. Pick your primary jurisdiction (Canada\u2019s CASL is the strictest — recommended baseline). Pick HTML or plain text output. Copy and paste into your email template.

Why this tool matters

Marketing email legally requires specific footer content under CAN-SPAM (US), CASL (Canada), and GDPR/PECR (EU). Missing items can result in fines: up to $51,744 per violation under CAN-SPAM, $10M CAD per violation under CASL. Most email service providers (Mailchimp, Klaviyo, HubSpot) auto-insert footers — but verifying they\u2019re actually compliant takes a tool like this.

Common use cases

• Pre-launch compliance check on new email programs
• Migrating to a new ESP and rebuilding templates
• Quick template generation for one-off newsletter sends
• Auditing client emails before a marketing program kickoff
• Helping product teams add transactional-email footers

Why CASL is the strictest standard

Canada\u2019s CASL requires opt-in consent (not just opt-out), mandatory sender identification, and proof of consent for every recipient on demand. Designing for CASL automatically meets CAN-SPAM and GDPR. If your list spans North America, CASL compliance is the safest baseline.

Frequently Asked Questions

Is this footer enough to be fully compliant?
It covers the visible footer requirements. Full compliance also requires opt-in consent (CASL/GDPR), retention records, working unsubscribe (honored within 10 business days), and not buying lists. The footer is necessary, not sufficient.

What about transactional emails (receipts, password resets)?
Transactional emails are exempt from CAN-SPAM unless they also contain marketing content. CASL is stricter — it applies to all “Commercial Electronic Messages” (CEMs). When in doubt, include the footer.

Do I need my physical address in plain text?
Yes — US CAN-SPAM specifically requires it in every commercial email. PO Box numbers count as long as you actually receive mail there. Virtual offices count if they receive mail.

What if I\u2019m sending from a freemium business address?
You need a valid physical mailing address. If you don\u2019t have one, get a registered agent or virtual mailbox service ($50-100/year). Lying about it can trigger investigations.
