Quick Guide to Email Marketing Laws for Bloggers

As a lawyer for bloggers and online business owners, and a blogger myself, I know email lists aren’t just “nice to have.” These days they’re the backbone of a profitable blog. At the same time, email marketing comes with legal rules that too many creators overlook, sometimes until it’s too late.

If you’re a blogger who collects email addresses, sends newsletters, or promotes products through email, you must follow anti spam laws, include proper disclosures, and protect your subscribers’ personal data.

Yes, even if your list is small. Yes, even if you’re “just casually blogging.”

Here are the email marketing laws you should be familiar with if you have a mailing list for your blog.

Why Email Marketing Laws Matter For Bloggers

Your email list feels personal. It’s you and your subscribers. Cozy. Friendly. Maybe a little chaotic. But legally? Email marketing is regulated. Governments care about three big things:

• People shouldn’t get spammed without consent
• People should know who is emailing them
• People’s personal information should be protected

If you ignore those rules, you could face fines, account shutdowns, or legal complaints. When lawyers talk about “liability,” we’re talking about your legal responsibility and the risk of having to pay money because you broke a rule. Nobody wants that surprise. So let’s get specific.

The CAN-SPAM Act: The Core Email Marketing Law in the U.S.

In the United States, the main law governing commercial email is the CAN-SPAM Act.

If you’re a U.S.-based blogger, this law applies to you. If you’re outside the U.S. but emailing people in the U.S., it can still apply.

Here’s what the CAN-SPAM Act requires:

• You can’t use misleading subject lines
• You must clearly identify who the email is from
• You must include a valid physical mailing address
• You must include a clear and easy way to unsubscribe
• You must honor unsubscribe requests promptly

That unsubscribe link? It’s not optional. And you can’t hide it in light gray font at the bottom in size 6 text.

Also, once someone unsubscribes, you can’t just quietly re-add them to a different list later. That’s a fast way to create legal exposure, which simply means legal risk.

GDPR and International Email Marketing Laws

If you have subscribers in the European Union, the General Data Protection Regulation, usually called GDPR, may apply to you.

GDPR is stricter than U.S. law. It focuses heavily on consent and data protection.

Under GDPR:

• You must have clear, informed consent before adding someone to your list
• Pre-checked boxes are not valid consent
• You must explain how you’ll use their data
• You must allow them to access or delete their data

If you’re thinking, “But I’m just a small blogger,” that doesn’t automatically exempt you. GDPR applies based on where your subscribers are located, not just where you live. Canada has its own law too, Canada’s Anti-Spam Legislation, often called CASL, and it’s even stricter in many ways.

If you’re building a global audience, you need to think globally about compliance.

Do Bloggers Need Consent Before Sending Emails?

This is one of the biggest questions around email marketing laws for bloggers.

In most cases, yes, you should get express consent. That means someone knowingly gave you their email address and agreed to receive emails from you.

Good examples of valid consent:

• They signed up through your opt in form
• They downloaded your freebie and checked a box agreeing to receive emails
• They joined your newsletter intentionally

Bad examples:

• You scraped their email from a website
• They emailed you once, so you added them to your list
• You bought an email list

Buying lists is almost always a terrible idea legally and ethically. It increases your risk of spam complaints and platform shutdowns.

What About Affiliate Emails and Sponsored Promotions?

If you’re sending emails that include affiliate links or sponsored content, you also need to follow FTC disclosure rules. The Federal Trade Commission requires that material connections, meaning financial relationships, be clearly disclosed.

So if you earn a commission from a link in your email, you need to say so clearly and plainly. Not hidden at the bottom. Not buried in vague language. Something like: “This email contains affiliate links, which means I may earn a commission if you purchase through them.”

Clear. Honest. Simple.

Privacy Policies and Email Marketing Laws for Bloggers

If you’re collecting email addresses, you’re collecting personal data. That means you should have:

• A clear privacy policy on your website
• Language explaining how you collect, use, and store email addresses
• Information about third party providers like your email marketing platform

Your privacy policy should specifically mention email marketing and how users can unsubscribe or request deletion. If your current privacy policy is a generic free template you grabbed years ago, it’s probably time for an upgrade.

What Happens If You Ignore Email Marketing Laws?

Best case scenario, your emails go to spam. Worst case scenario:

• Your email platform shuts down your account
• You receive fines from regulators
• You get complaints or legal demands

Some fines under laws like CAN-SPAM can technically reach thousands of dollars per violation. That’s per email. Regulators don’t typically chase small bloggers for minor mistakes, but repeat or intentional violations can absolutely escalate.

The real risk for most bloggers is account suspension. If your email service provider shuts you down, you can lose access to your entire list. That list you spent years building. Gone.
