Email marketing is still one of the most direct ways to reach your audience. But that access depends entirely on permission. POPIA and GDPR both require explicit consent before you send a single marketing email, and for good reason.
Here is why sending only to subscribers who have opted in is the only approach worth taking.
Respect for Privacy
When someone opts in, they are giving you permission to contact them. That permission is the starting point for everything. Both POPIA and GDPR are clear: explicit consent is required before you send marketing communications. Assuming consent, or inferring it from a loosely related transaction, does not meet the standard.
Building Trust
Sending emails to people who never asked for them creates friction from the first interaction. It signals that you are not paying attention to what your audience actually wants. Subscribers who chose to hear from you are far more likely to engage, convert, and stay on your list.
Protecting Your Sender Reputation and Deliverability
Spam complaints are a direct signal to email service providers that your mail is unwanted. A rising complaint rate pushes your mail into the junk folder, or gets you blocked outright. Once your sender reputation takes a hit, recovering it takes time and effort. Keeping your list clean and consent-based is the simplest way to avoid the problem in the first place.
Legal Compliance
POPIA and GDPR carry real consequences for non-compliance: fines, regulatory scrutiny, and reputational damage. Both regulations require you to obtain explicit consent before sending marketing emails and to honour the right to unsubscribe at any time. These are not optional guidelines.
Handling Unsubscribes Correctly
When someone opts out, remove them promptly and keep them off your list. Do not re-add them without fresh, explicit consent. Adding an unsubscribed contact back without permission breaches both regulations and erodes whatever trust remained.
Why Purchased Databases Are a Problem
Buying an email database might look like a shortcut to a bigger audience. It is not. Those lists contain addresses gathered without consent from your specific business. The people on them never asked to hear from you.
Sending to a purchased list almost always produces high spam complaint rates, deliverability problems, and potential legal exposure under POPIA and GDPR. No short-term gain in list size is worth that risk.
Build Your List Organically
Focus on quality rather than volume. Offer genuinely useful content, clear opt-in prompts on your website, and relevant incentives at the right moments in the customer journey. A smaller list of engaged subscribers who chose to hear from you will consistently outperform a large list of cold or uninterested contacts.
Organic list growth takes longer, but it produces subscribers who actually open, click, and buy. It also keeps you on the right side of POPIA and GDPR without needing to second-guess your data practices.
Compliance and good marketing point in the same direction: earn permission, respect choices, and communicate with people who want to hear from you. Your sender reputation, your deliverability, and your audience relationships all depend on it.

Frequently asked questions
- Does POPIA require explicit opt-in consent for email marketing?
- Yes. POPIA requires that you obtain explicit consent from a person before sending them marketing communications. Implied or assumed consent does not meet the standard.
- Can I buy an email database and send marketing emails to it?
- No. Purchased databases contain addresses collected without consent from your specific business. Sending to them breaches POPIA and GDPR, typically generates high spam complaints, and damages your sender reputation.
- What should I do when a subscriber unsubscribes?
- Remove them from your list promptly and do not re-add them without fresh, explicit consent. Continuing to email an opted-out contact is a breach of both POPIA and GDPR.
- How does a low-quality email list affect deliverability?
- High spam complaint rates signal to email service providers that your mail is unwanted. This reduces inbox placement rates and can result in your domain or IP being blocked. Keeping your list to opted-in, engaged subscribers is the most reliable way to protect deliverability.
