Before we proceed for the strategies, let’s answer the most important question first.
Is sending cold emails illegal?
Cold emailing is legal in most regions if it follows the right email compliance rules of the region.
These email marketing laws differ based on where you operate and who you are emailing.
You need to understand the differences between cold emails, unsolicited emails, and spam to actually be safe from any penalties or restrictions.
- Cold emails → Messages sent to potential prospects with a legitimate business interest but without prior interaction.
- Unsolicited emails → Messages sent without prior consent; may be legal if they meet compliance requirements.
- Spam emails → Bulk, deceptive, or misleading emails that violate anti-spam laws and lack an opt-out option.
Now to maintain compliance, follow the email marketing regulations of your target region (such as GDPR, CASL, CAN-SPAM etc.)
Different email compliance laws and regulations
To comply with anti-spam laws for cold emailing, you first need to understand the email compliances and regulations of different countries where your prospects might be located.
So, let’s take a look at the most important email compliance laws first.
1) CAN-SPAM Act (United States)

Best practices for maintaining cold email compliance
Following are some of the best practices that you should follow in your cold email outreach process to stay clear of anti-spam laws.
1. Obtain proper consent
Determine whether explicit or implied consent is required based on the laws in your target region.
For example, under GDPR, you must obtain explicit consent before emailing prospects, whereas CAN-SPAM allows outreach if you provide an opt-out option
When in doubt, always use permission-based outreach to stay compliant.
2. Provide a clear & easy opt-out system in every email
Include a visible and functional unsubscribe link in every cold email.
Make opt-out requests easy to complete, and remove unsubscribers immediately from your email list. (within 10 business days for CAN-SPAM compliance).
3. Use business email addresses for cold outreach
Avoid sending cold emails from free email services like Gmail or Yahoo, as they appear unprofessional and may trigger spam filters.
Always send cold emails from business email addresses with custom secondary domains (e.g., [email protected]) to improve credibility and deliverability.
For example, if you are doing cold email outreach ⤵️
❌ [email protected] → reduce trust + looks unprofessional ☹️
✅ [email protected] → signals legitimacy + increases response rates 😃
4. Write helpful & honest email subject lines
Deceptive subject lines violate email compliance laws and may appear shady.
Such subject lines are mostly ignored and never opened by the recipients. So, your overall email campaign suffers from it.
Ensure your subject lines are clear, relevant, and accurately describe the content of your email.

5. Include your contact information in emails
Always provide your company’s name, physical address, and a working reply-to email to comply with email laws and establish trust.
And it’s also a good idea to include –
- Your company’s Linkedin
- Website
- Social media channels (Youtube, X etc.)
- Ratings and reviews
For some additional branding and trust-building
💡Practical tip: You can include the above information in the email signatures.
6. Keep the email lists clean & updated
Regularly remove inactive contacts, invalid addresses, and unsubscribed recipients to avoid sending emails to people who don’t want them.
This will save you from unwanted spam complaints and your sender reputation doesn’t get hurt.
7. Process email unsubscribe requests immediately
Ignoring unsubscribe requests can result in email compliance violations and damage your sender reputation.
Always process opt-outs promptly and ensure recipients are removed from future emails.
💡 Practical tip: Try to process it within 24 hours as a best practice.
