Database growth is something every digital marketer chases. The logic is sound: more subscribers means more chances to convert. But there are right and wrong ways to build that list, and the wrong ways will cost you.
POPIA has been in effect since 1 July 2021, so the legal requirements are not new. What is worth revisiting is the mindset behind them. Your audience already values their privacy. They expect relevant communication and have no patience for unsolicited content. Think about your own inbox and how you respond to a campaign you never signed up for. Chances are you disengage from that brand entirely. First impressions matter.
When you approach database growth with your audience's needs front and centre, POPIA compliance follows naturally. Here is how to do it properly.
Make It Easy
The first step is removing friction. Your audience engages with your brand in multiple ways, and every touchpoint should offer a clear path to your mailing list.
A sign-up form on your website is table stakes. Go further. Add links on your social channels that lead directly to sign-up forms. Promote your mailing list across every channel you own and give people a reason to subscribe.
The specific channels that make sense will depend on your business and industry, but the principle is the same: wherever someone encounters your brand, they should have an easy way to start a more direct conversation through email.
Most people who already support your brand are willing to hear from you. They just need a clear prompt. Be upfront about what kind of content they can expect, and then stick to that promise.
Incentivise
Even when joining your list is an easy decision, people often need a reason to act. Most of us are protective of our personal email addresses. We do not want inboxes full of content we never asked for.
An incentive is how you earn that commitment. Options include a discount on a future purchase, a free resource like a whitepaper or guide, or exclusive content that regular visitors would not see until later. What works best depends on your business, but the principle is the same: offer something of real value in exchange for permission to communicate.
Then follow through. Whatever you promised on the sign-up form, deliver it. No exceptions.
The Nike sign-up form below is a solid example. It states the benefits of joining clearly and offers a Facebook sign-up option to reduce effort for the subscriber.
Consent is Paramount
Buying databases or scraping email addresses from the web is not a growth strategy. It is a POPIA violation, and it will damage your sender reputation. A small, engaged list will always outperform a large, indifferent one.
Treat your subscribers' right to privacy as standard practice, not a compliance checkbox. When someone joins your list, it is usually for a specific reason. If they signed up for product offers, send product offers. If they signed up for industry news, send industry news. Deliver what you promised.
Double opt-in is one of the most effective tools for keeping your list clean. After someone submits their details, they receive a confirmation email and must click a link to complete the sign-up. This filters out spam registrations and people who only wanted the incentive. It also means every address on your list belongs to someone who actively chose to be there.
From a POPIA perspective, double opt-in gives you a clear, timestamped record of consent. That is not a minor benefit.
The Global Home Goods example below shows this process done well. The confirmation email thanks the subscriber, restates the incentive, and asks them to confirm. It is clear and gives the subscriber no reason to drop off.
Making It Work Long-Term
Organic database growth takes time. Factor in POPIA's requirements and it can feel like a lot to manage. But the two are not in opposition. A consent-first approach to list building is also a better marketing approach, full stop.
Focus on making sign-up easy, offering genuine value, and keeping your list clean with double opt-in. Those three things will give you a database that actually converts.

Frequently asked questions
- Does POPIA require double opt-in for email marketing in South Africa?
- POPIA does not explicitly mandate double opt-in, but it does require that you can prove consent was freely and actively given. Double opt-in produces a timestamped confirmation record that satisfies this requirement and is widely recommended as best practice.
- Can I buy an email list and use it for marketing under POPIA?
- No. POPIA requires that the people on your list have consented to receive communications from your organisation specifically. A purchased list does not meet that standard and using one exposes your business to regulatory risk.
- What incentives work best for growing an email list?
- The most effective incentives offer genuine value: a discount on a first or future purchase, a free resource relevant to your audience, or early access to content or products. The key is that the incentive matches what your audience actually wants, and that you deliver it immediately after sign-up.
- How do I keep my email list engaged after people sign up?
- Send what you promised during sign-up. If subscribers opted in for product updates, send product updates. Relevance is the main driver of engagement. Segment your list early and set clear expectations in your welcome email so subscribers know what to expect and how often.
