Free Email Footer Generator

Email footer vs email signature — they're not the same

The term "email footer generator" gets used to mean two completely different things. We picked a side: this tool builds the legal compliance block that sits at the bottom of marketing and transactional emails. It includes things like your physical mailing address, an unsubscribe link, and a privacy policy reference. Without it, your campaigns violate CAN-SPAM, GDPR, CASL, or whichever law applies to your audience.

An email signature is something different. That's your personal sign-off at the bottom of one-to-one emails — name, job title, company logo, social links, headshot. If that's what you came for, head to our Email Signature Generator — same brand, different tool. 20+ templates, exports for Gmail, Outlook, Apple Mail.

What the law actually requires

Every major jurisdiction has anti-spam rules with specific requirements for what marketing emails must include. We support the six biggest ones — selecting them above pulls in the right fields automatically:

CAN-SPAM (United States)

The US federal anti-spam law applies to any commercial email going to or from US recipients. Three core requirements:

• Accurate sender ID — the "from" line and subject must not mislead. Your company name should appear in the footer.
• Valid physical postal address — a real street address or PO Box. PO Boxes are explicitly allowed under FTC guidance.
• Functional unsubscribe — one-click or short-form. Honor opt-outs within 10 business days.

Maximum FTC penalty: $51,744 per non-compliant email (as of 2024). The FTC has used CAN-SPAM to fine companies tens of millions — Adobe Air's $250K, Spammer-X's $11M. A footer is the cheap insurance.

GDPR (European Union)

The EU General Data Protection Regulation covers any business that processes EU residents' personal data — which includes their email address. For marketing email, GDPR requires:

• Data controller identification — your company name as the entity collecting and processing data
• Link to your privacy policy explaining how you process the recipient's data, with retention periods and their rights
• Way to withdraw consent — your unsubscribe link, plus ideally a preferences page

GDPR fines run up to €20M or 4% of global revenue, whichever is higher. Most footer-only violations result in smaller fines but they pile up — Italy's Garante issued €60K, €40K, and €25K fines for various email-related issues in 2023 alone.

PECR (United Kingdom)

UK Privacy and Electronic Communications Regulations layer on top of UK GDPR. The key extra: for limited companies, your Companies House registration number belongs in the footer alongside the basic GDPR fields. The ICO has fined British Airways £20M and Marriott £18M under GDPR/PECR combinations.

CASL (Canada)

Canada's Anti-Spam Legislation is the strictest of the major regs. It requires express opt-in consent before the first message (no soft opt-in), full sender identification with mailing address, AND a contact email separate from the unsubscribe link. CASL penalties run up to CAD $10M per violation for businesses.

Australia Spam Act 2003

The lightest of the bunch — sender ID + functional unsubscribe + honor opt-outs within 5 business days. Australia's ACMA has issued penalties of AUD $610K (Optus), AUD $2.6M (Commonwealth Bank). The 5-day rule is stricter than CAN-SPAM's 10.

Germany Impressum (§5 TMG)

The German Telemedia Act adds an Impressum requirement on top of GDPR. For commercial entities, the footer needs business registration number (Handelsregister), contact email, and full mailing address. German privacy regulators (LfDI Baden-Württemberg, BfDI) actively pursue Impressum violations — €5K-€50K fines are typical.

A side-by-side comparison

What changes between the major regulations? This table shows the absolute minimum each requires in the footer:

If you send to recipients in multiple regions, your footer needs the union of fields across every applicable regulation — that's exactly what our tool builds. Select all jurisdictions you reach above and we'll show you which fields are still required.

Plain text vs HTML — when to use which

Most email service providers (Mailchimp, ConvertKit, Klaviyo, Customer.io) let you set a separate footer for HTML and plain-text versions of your campaigns. You probably want both:

• HTML version — used by 95%+ of recipients. Renders with styled links, your brand colors (subtle), proper line spacing. Our HTML output uses table-based layout, which Outlook desktop renders consistently (div-based footers break in Outlook).
• Plain text version — used by recipients who've configured their client to plain-text mode, or by some accessibility tools, or in the body of automated transactional emails. Required as a separate part by most ESPs to maximize deliverability.
• Markdown version — for tools like Substack, Buttondown, or ConvertKit's broadcast blocks that accept Markdown formatting. Less common but useful when applicable.

Our tool generates all three formats from one input. Copy whichever your ESP expects.

Common footer mistakes to avoid

1. Using your home address. CAN-SPAM requires a physical address; it doesn't require your home address. A PO Box, a UPS Store mailbox, or a coworking-space mailing address all satisfy the rule. Don't burn your home address to send a newsletter.

2. Putting the unsubscribe link in 4pt grey-on-white text. CAN-SPAM and GDPR both require unsubscribe to be "clear and conspicuous." Hiding it gets you sued. Make it a clear link with enough contrast to be obviously a link.

3. Forgetting the privacy policy link for EU/UK recipients. GDPR transparency obligations require it. Many US-based newsletters omit this and get flagged when they pick up EU subscribers organically.

4. Missing the company registration number on UK / German emails. PECR for UK limited companies + §5 TMG for German entities both require the registration number in any commercial communication. Easily missed by non-EU senders who add EU subscribers later.

5. Embedding the unsubscribe URL but not making it a working link. Sounds obvious — but it's the most-cited cause of CAN-SPAM enforcement actions. Test that your ESP's merge tag resolves correctly before sending. Send a test to yourself + a coworker; click the unsubscribe link from BOTH; confirm it processes.

Pairing this with the rest of your email stack

A compliant footer is one piece of the deliverability puzzle. Some tools that fit alongside it:

Verify your list before you send

Sending to dead addresses tanks your sender reputation. Our email verifier opens an SMTP conversation with each recipient mail server to confirm the mailbox accepts mail. 200 free credits with no card on signup. Run new lists through it before importing into your ESP.

Catch syntax errors at signup time

Typos at signup (`kevin@gmail.con`) become bounces three days later. Our email syntax checker shows you the regex + provider-specific rules you should validate against in your signup form code. Free.

Sign every one-to-one email like a pro

Marketing footers live at the bottom of automated campaigns. Personal sign-offs live at the bottom of every email you send by hand from your inbox. Different need, different tool — our Email Signature Generator builds a professional HTML signature with your name, photo, title, and social links. 20+ templates, export-ready for Gmail and Outlook.
