Email has a bit of a bad rap. For every brand doing things right, there’s another one out there flooding inboxes with spammy subject lines, sneaky fine print, and a complete disregard for consent. Why is this a problem? Because the short-term wins come at the cost of long-term trust.
Good email marketing isn’t just about results, it’s about getting your results whilst being responsible.
Here’s where to draw the line, and why staying ethical isn’t just the right thing to do (it’s 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 data protection laws like POPIA, GDPR, and CAN-SPAM. If someone didn’t say “yes,” then it means “no.” Simple.
2. Transparency over tricks
The line:
Don’t mislead people just to get opens or clicks
Why it matters:
Clickbait subject lines, shady fine print, or hiding the unsubscribe button might bump your open rate today, but it’ll trash your credibility tomorrow.
Be clear about who you are, what the email is about, and what the recipient can expect. If you make a promise in the subject line, your content had better deliver.
3. Unsubscribing shouldn’t feel like a maze
The line:
Joining your database should be easy, and leaving it should be just as easy.
Why it matters:
Yes, losing subscribers sucks. But forcing people to jump through hoops to unsubscribe (or worse, pretending the button’s not there) is not only unethical, it’s illegal in many places.
The easier you make it to leave, the more likely they’ll come back, or at least remember you positively.
4. Don’t abuse the data
The line:
Just because you can personalise, doesn’t mean you always should.
Why it matters:
Data is powerful. It can help you deliver relevant, timely content. But there’s a fine line between helpful and creepy.
Use data to improve the experience, not to stalk your customers. Don’t sell, share, or mishandle subscriber info. And always be upfront about what you collect and why.
5. Always be human
The line:
Don’t lose your brand’s voice and values by over-automating.
Why it matters:
Yes, automation and AI are incredible tools, but they should enhance the experience, not replace empathy, humour, or authenticity.
Emails are still being read by humans, so don’t lose the human touch in your communications.
Why ethical marketing wins in the long run
- Trust builds loyalty. People are more likely to buy (and keep buying) from brands they trust.
- Good reputation = better deliverability. Spam complaints hurt your sender score and land you in the junk folder.
- Compliance protects your business. Avoid fines, lawsuits, and PR nightmares by sticking to the rules.
The bottom line
Email marketing isn’t 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. If you respect that, they’ll stick around.
So draw the line where it counts. Then never cross it.
