Email has a bit of a bad rap. For every brand doing things right, there's another one flooding inboxes with spammy subject lines, sneaky fine print, and a complete disregard for consent. The problem is that the short-term wins come at the cost of long-term trust.
Good email marketing is not just about results. It's about getting those results responsibly.
Here's where to draw the line, and why staying ethical is also just good business.
1. Consent is not optional
The line: Never send emails to someone who hasn't asked for them.
Why it matters: Consent is the foundation of ethical marketing. That means no bought lists, no sneaky opt-ins, and no "they gave us their business card once" excuses.
Respecting consent builds trust, protects your sender reputation, and keeps you on the right side of POPIA, GDPR, and CAN-SPAM. If someone didn't say yes, the answer is no. Simple.
2. Transparency over tricks
The line: Don't mislead people just to get opens or clicks.
Why it matters: Clickbait subject lines, buried fine print, or a hidden unsubscribe button might lift your open rate today, but they'll trash your credibility tomorrow.
Be clear about who you are, what the email is about, and what the reader can expect. If you make a promise in the subject line, the content had better deliver.
3. Unsubscribing shouldn't feel like a maze
The line: Joining your database should be easy. Leaving it should be just as easy.
Why it matters: Losing subscribers is frustrating. But forcing people through hoops to unsubscribe, or hiding the option entirely, is unethical and illegal in most markets.
The easier you make it to leave, the more likely someone is to return, or at least remember your brand without resentment.
4. Don't abuse the data
The line: Just because you can personalise doesn't mean you always should.
Why it matters: Data can help you send relevant, timely content. But there's a clear line between helpful and intrusive.
Use data to improve the experience, not to track subscribers in ways that feel invasive. Don't sell, share, or mishandle subscriber information. Be upfront about what you collect and why.
5. Always be human
The line: Don't sacrifice your brand's voice and values by over-automating.
Why it matters: Automation is a powerful tool, but it should improve the experience, not strip out the empathy, humour, or authenticity that makes your brand worth hearing from. Your emails are still read by people. Write like it.
Why ethical marketing wins in the long run
- Trust builds loyalty. People are more likely to buy, and keep buying, from brands they trust.
- A good sender reputation means better deliverability. Spam complaints damage your sender score and push you into the junk folder.
- Compliance protects your business. Sticking to the rules keeps you clear of fines, legal exposure, and reputational damage.
The bottom line
Email marketing is not just a numbers game. It's a relationship.
Every subscriber is a real person who gave you access to their inbox, a space they control, curate, and protect. Respect that, and they'll stick around.
Draw the line where it counts. Then never cross it.

Frequently asked questions
- What does POPIA require from email marketers in South Africa?
- POPIA requires that you have a lawful basis for processing personal information, which in most email marketing contexts means obtaining clear, informed consent before sending. You must also tell subscribers what data you collect, why you collect it, and give them a straightforward way to opt out at any time.
- Why does making it easy to unsubscribe actually help my email programme?
- A subscriber who can leave without friction is less likely to mark your email as spam. Spam complaints directly damage your sender reputation and hurt deliverability across your whole list. A clean, engaged list outperforms a large, resentful one every time.
- Is personalisation always a good idea in email marketing?
- Not always. Using data to send relevant content at the right time is genuinely useful. Using it in ways that feel intrusive, such as referencing browsing behaviour in a way that surprises or unsettles the reader, can erode trust faster than a generic email would. The test is whether the personalisation helps the reader or just signals that you've been watching them.
- Can I email people who gave me their contact details in person, like at an event?
- A business card or a sign-up sheet at an event is not the same as consent to receive marketing emails. Under POPIA and similar frameworks, you need a clear, specific opt-in for marketing communications. Best practice is to follow up with a confirmation email that lets the person choose to subscribe, rather than assuming permission.
