Is Cold Email Illegal? (Laws in the US, UK, EU, Australia, South Africa, and Canada)

The short answer is no, cold emailing is not illegal. The long answer has a "but" in it. And that "but" depends on where your cold outreach takes place. Like others, you must follow specific rules and regulations that vary with:
Location
Government
Customs
Avoiding Legal Pitfalls in Your Outreach
Depending on where your prospects are, you will have to align your cold email campaigns to ensure you don't violate specific laws. For example, when you visit Venice, avoid feeding pigeons because they might attract a fine of €500. Laws concerning cold emailing aren't as bizarre, but they can injure your cold outreach. The most well-known regulations, such as the CAN-SPAM Act and GDPR, lay down rules for cold emailing in the US and Europe, respectively. We'll get to that shortly. But before that, we will address a question that continues to haunt salespeople today: "How do I avoid spam?"
What is a Spam Email?
According to Norton Security, spam emails are unwanted, unsolicited emails sent in bulk. B2C marketing emails, newsletters recipients never signed up for, phishing emails, and sales emails sent to an unreasonably large number of people can be spam.
Why Targeted Outreach Trumps Mass Blasts
This spray-and-pray outreach strategy is a fast track to getting caught by spam filters, losing sender reputation, and reducing your email deliverability rate, besides being a complete 180 from what sales outreach entails:
Researching leads
Their pain points
Contacting leads that fit your ideal customer profile
Personalizing your outreach.
Why Do My Cold Emails Go to the Spam Folder?
Before we get to the why, let’s understand the how. There are two significant ways your cold email might grace the spam folder:
1. If the email service provider’s (ESP) spam filters are triggered
Your cold emails don’t get a free pass to your prospect’s inbox. Your prospect’s ESP has spam filters that help sift unsolicited commercial messages out of the mix, so as not to burden the inbox.
2. If the recipient marks you as spam
This can happen when the content of your email adds no value to the recipient, includes unnecessary urgency, conceals the sender’s identity, etc. This annoys the prospect and drives their cursor to the spam button. That said, here are some reasons why your cold email might end up in the spam folder:
The email’s content, subject line, or both contains spam trigger words
Sender information is inaccurate
You don’t have permission from the recipient to send emails
Email authentication is incomplete
The unsubscribe link is missing
The recipient marked your email as spam
These are the most common reasons your emails aren’t reaching their destination. And so, if you’re looking for a quick check, analyzing your cold emails with these points in mind isn’t a bad start. Nevertheless, understanding cold email laws is best to get the whole picture.
What Is the Difference Between Cold Email and Spam?
Kevin Hopkinson, who manages marketing operations at ZoomInfo, outlines the three elements differentiating cold emails from spam:
1. Intention
A key difference between cold emails and spam is the message's intent. “Targeted cold email lists involve a personalized message sent to potential clients or contacts with legitimate business intent,” Hopkinson says. “Spam, on the other hand, is unsolicited bulk messaging sent indiscriminately, such as promoting irrelevant or misleading products to random unqualified contacts.”
2. Personalization
Effective cold emails are personalized. They address the recipient by name, reference specific details about their business or role, and offer solutions tailored to their needs. Spam emails lack this personalization, appearing generic and often irrelevant to the recipient. “Tailoring content to the recipient’s preferences, behaviors, and past interactions enhances customer experience, fosters brand loyalty, and allows conversations to quickly improve into conversions with relevance and value,” Hopkinson says.
3. Straightforwardness
Well-crafted cold emails are transparent about their purpose. They clearly state why the sender is reaching out and what they offer. “Spam is vague, overly promotional, and irrelevant in every way to the audience receiving it,” Hopkinson says.
Cold Emailing Rules and Regulations in Different Countries
Is cold email legal in the United States?
Cold email is legal in the United States. Nonetheless, you must comply with the CAN-SPAM Act. The CAN-SPAM Act outlines the legal requirements for all commercial messages (emails) to advertise or promote a product or service.

The CAN-SPAM Act states that recipients have the right to opt out of receiving emails and includes penalties up to USD 50,120.00 for violations. This law applies to all commercial email messages and is not just applicable to bulk emails.
How to comply
You must use accurate header information. Your "From," "To," and "Reply-To" must be accurate and not misleading. Your subject lines must not be deceptive and represent your email's content. State what your email is about. You must mention that your email is an advertisement. Mention your physical location. You should add this to your email signature. This can be your street address or the post office box you registered with the U.S. Postal Service. Tell the recipient how they can opt out of receiving future emails from you.
Is cold email legal in the United Kingdom?
Cold email is legal in the United Kingdom, but you should know the Privacy and Electronic Communications Regulations (PECR).
What does the law state
In the United Kingdom, the Privacy and Electronic Communications Regulations (PECR) require businesses to obtain prior consent before sending unsolicited commercial email to individuals. PECR also requires firms to include a valid contact address so recipients can opt out or unsubscribe.
Navigating UK Cold Email Rules: B2B and Consent-Based Strategies
You might be wondering how to send cold emails in the UK if you need first to receive consent. You can't send cold emails to private individuals, but you can send cold emails to businesses. You can send commercial emails to people who have given you consent through a third party, such as a reseller or a corporation within your group. An example could be if a potential client has already opted in to receive emails from your parent company, you can send them cold emails.
How to comply
Apart from complying with the above regulations, below are some things you can do to stay compliant in the UK: Allow your recipients to opt out of future emails. Provide your business address (you can do this in your signature). Don't use deceptive subject lines. Your subject line has to be relevant to the content of your email.
Is cold email legal in the European Union (EU)?
Cold email is legal in the European Union, but you should know about the General Data Protection Regulation (GDPR).
What does the law state
In the European Union, the General Data Protection Regulation (GDPR) regulates commercial email, requiring businesses to obtain consent before sending unsolicited emails to individuals. Nevertheless, this rule has some exceptions, such as when the email is necessary for the legitimate interests of the sender or the recipient. The GDPR also requires businesses to provide an opt-out option and accurate email contact information.
How to comply
You can comply with the GDPR's requirements by clearly and concisely explaining why you are contacting the recipient and offering an easy way to opt out. You must also ensure that the emails you send are necessary for the legitimate interests of the sender or the recipient.
Is cold email legal in Canada?
Cold email is legal in Canada, but it's more difficult as you must obtain explicit consent first. You should be aware of the Anti-Spam Legislation (CASL).
What does the law state
In Canada, the Anti-Spam Legislation (CASL) also regulates commercial email, requiring businesses to obtain prior consent before sending emails, including cold emails, to individuals. Nonetheless, implied consent can still be allowed, for example, if you get an email address from a mutual contact who already has a business relationship with the recipient. CASL also requires businesses to include an opt-out option and accurate contact information in their emails.
How to comply
After you've received explicit or implied consent from the recipient, you should follow the guidelines below to stay compliant: State who you are with accurate contact and address information. Give the recipient a straightforward way to opt out of future emails. Ensure that your email is relevant to the recipient.
Cold Email Laws in South Africa
The Protection of Personal Information Act (POPIA) governs cold emailing in South Africa. The law, which was enacted on July 1, 2020, aims to protect individuals' privacy by ensuring that their data is handled responsibly. A key provision of the POPI Act that concerns cold emailing is that individuals must give explicit consent for their personal information to be collected and processed. That all but makes a cold email illegal. Penalties for violating the provisions of the POPI Act can be up to R10 million or 10 years imprisonment.
Cold email in other jurisdictions
Many countries have privacy regulations that you need to consider. You must consult with a lawyer when conducting business in new markets. You want to ensure compliance with the local laws and regulations so that you don't find yourself fined. You don't want your business to end up being one that's on a list of those that are not allowed to trade in certain areas.

Top 10 Strategies to Send Compliant Cold Emails

1. Target the Right People to Stay Compliant with Cold Email Regulations
To comply with cold email regulations, you must target the right people. This means only sending cold emails to people genuinely interested in your product or service. For this reason, you should NEVER send cold emails to personal email addresses. Only send cold emails to relevant business email addresses.
Tailoring Cold Emails for Maximum Impact
Each cold email you send needs to be personalized to each lead. You should not send mass email campaigns to random email lists. Instead, you need to be very specific when finding leads. Use our LinkedIn Email Finder Google Chrome extension to find LinkedIn leads relevant to your niche and offering.
2. Make Opting Out Easy for Cold Email Recipients
All of your cold emails should allow the recipient to opt out of receiving future emails. The best way to do this in the context of cold email is to write something like “Let me know if you’d be interested in this” or “If you’re not the right person to contact about this, then please let me know or please forward this email to the right person.” If recipients want to opt out, they can simply reply with “No thanks.” You can then remove their data from your list and never email them again.
Protect Your Recipients’ Data
It is essential to keep your recipients’ data secure. If your recipients opt out of your cold email campaigns, you must delete their data from your database.
Avoid Deceptive Subject Lines
Deceptive subject lines might open the email, but once the prospect realizes you’ve exaggerated, misled, or lied to them, it’s a one-way ticket to the spam folder. And with that, your hopes and dreams of nurturing them down the sales funnel go out the window. Your cold emails should help you build a long-term relationship with your prospect.
Protecting Your Reputation from Misleading Subject Lines
Starting on the wrong foot can cost you that individual prospect, your email deliverability rate, and your sender’s reputation. Here are some examples of misleading subject lines:
You’ll never believe this!
Want to become the best?
Free goodies inside!
Not to forget—once bitten, twice shy. Your prospect won’t make the same mistake twice. If by some fluke your cold email does make it to their inbox, seeing a subject line like this will be proof enough for it to remain unopened or get transferred to the spam folder.
3. Refine Your Cold Prospect List Regularly
If you send unsolicited emails to inactive or invalid contacts who don't respond, spam filters may flag your emails as spam. So, when cold emailing, conduct email validation to confirm you're reaching active users. Neglecting this can:
Increase bounce rates
Harm your sender's reputation
Hinder email deliverability
You can use email validation tools to save time and focus on crafting personalized sales pitches. The email verification platform can help you in:
Detecting syntax errors in email addresses.
Authenticating the recipient's domain via DNS checks.
Verifying the existence and receptivity of the email address.
4. Write Meaningful Subject Lines for Cold Emails
Craft a relevant subject line that reflects the content of your cold email. This transparency in subject lines falls under email marketing laws like the CAN-SPAM Act in the USA or the GDPR in Europe. Meaningful and honest subject lines establish trust with the recipient, improve the deliverability rate, and enhance the sender’s reputation.
Avoiding Deception for Sustainable Engagement
On the contrary, if you use misleading subject lines, your open rate might increase. But, once your prospect realizes it was just clickbait and exaggeration, they may mark you as spam or unsubscribe. A study by Nerdy Joe reveals that using irrelevant or unclear subject lines can decrease email open rates. Accurate subject lines also reduce the likelihood of your email being marked as spam, thereby improving the effectiveness of your cold email campaign.
5. Collect Emails Ethically
Many cold emailing regulations require consent, so ensure you collect your email audience's addresses ethically. Never buy lists of email addresses! Use clear opt-in forms to obtain explicit consent from individuals before adding them to your email list. Communicate how to use the email addresses you collect, and collect only necessary data.
6. Personalize Your Cold Emails
Some cold email regulations require that emails be relevant to the recipient. Personalizing a cold email is one way to do this. Addressing recipients by name or referencing their specific needs builds trust, demonstrating that you understand their unique needs. It also makes your emails resonate better with them.
7. Be Transparent About Your Identity
Imagine receiving an email from ‘gykaem@gmail.com’ with no profile photo, name, or email signature. That’s precisely what your prospect thinks; you go to the spam folder. Receiving an email from an unknown sender who does not identify themselves clearly can be unsettling for most. So, showcasing your details will help you build trust with your prospects and help your cold emails comply with these laws. These details include your:
Name
Designation
Company
Business address
8. Warm Up Your Email Address Before Cold Emailing
Just like a fresh pair of jeans needing a little stretching to gain that perfect fit, your new cold email address also needs a slight warming up before you start meeting your daily quotas. The reason is to help convince email service providers (ESPs) that you’re not here to spam recipients. In the process, you improve your email deliverability. Building on this and increasing your daily emails gradually helps warm up your email to meet the daily quota set by ESPs. In Google’s case, it’s 2000. Hitting 2000 on your first day will only flag your email address for suspicious activity and stop you before you begin.
