Don’t risk it! The critical role of consent when bulk emailing

Written by Chelsea-Jade De Wet | Nov 17, 2025 5:00:00 AM

Let’s be honest, bulk emailing can be a fantastic marketing tool. It’s fast, scalable, and gets your message in front of a lot of people with just one click. But there’s a fine line between smart marketing and straight-up spam. And if you’re not walking that line carefully, especially in South Africa, you could be inviting trouble.

Let’s unpack why getting proper consent is more important than ever, especially when bulk emailing in South Africa.

POPIA and email marketing compliance in South Africa

South Africa’s Protection of Personal Information Act (POPIA) has shifted the game for email marketers. POPIA doesn’t just encourage you to play fair, it legally requires you to. And at the heart of POPIA is consent.

Under POPIA consent requirements, you must obtain explicit, voluntary, and informed consent from a data subject before sending them marketing communications. This means no more adding people to mailing lists without them knowing, and definitely no scraping emails off the internet.

Failing to follow email spam regulations in South Africa can lead to serious consequences, including fines and reputational damage.

Unsolicited email: more risk than reward

Sending emails without consent isn't just legally risky, it’s a fast track to ruining your credibility. Unsolicited email penalties can be harsh, but the real danger is what it does to your brand.

When someone receives an email they never signed up for, it feels invasive. At best, they hit "unsubscribe". At worst, they report you as spam, tell their friends, and blacklist your domain. That’s not just one lost lead; it’s a ripple effect of lost trust.

It also shows a disregard for email data subject rights, which include the right to know how their data is being used, and the right to opt out at any time. Respect those rights, and you’re showing your audience that your brand is transparent and trustworthy.

Consent is good business

Here’s the twist: getting proper consent isn’t just about staying legal. It’s about getting better results.

A solid opt-in email strategy leads to higher open rates, better engagement, and more meaningful connections. When someone chooses to hear from you, they’re already interested. That means they’re more likely to click through, take action and convert.

On the other hand, cold emails might go straight to the junk folder, especially with today’s sophisticated spam filters. You’re better off building a smaller, high-quality list of engaged subscribers than blasting thousands of unqualified contacts.

Best practices for managing consent

So, how do you do consent right? It starts with having a customer consent management system in place. This could be integrated into your CRM or email platform, and it should track when and how someone gave consent, what they consented to, and when they opted out, if they ever do.

Here are a few consent best practices to follow:

  • Use clear opt-in forms: Whether it's on your website or a lead capture page, make sure it’s obvious what people are signing up for
  • Offer value upfront: Give people a reason to subscribe. Think free resources, exclusive listings, or expert insights
  • Use double opt-in: Send a confirmation email to ensure they really meant to subscribe. It might reduce sign-ups slightly, but it drastically improves list quality
  • Maintain easy bulk email opt-out mechanisms: Every email should have a clear, one-click unsubscribe option. It’s not just polite, it’s the law
  • Regularly audit your list: Remove inactive contacts, check that consent is documented, and update preferences when necessary

Ethics first: building trust and credibility

At the end of the day, ethical direct marketing practices are what separate professionals from spammers. In a world where people are increasingly protective of their personal information, showing that you respect their privacy earns you long-term loyalty.

Consent isn’t a hurdle; it’s a chance to start your relationship with potential clients on the right foot. It says: “We see you, we respect you, and we want to provide value.” That’s a powerful message.

The consequences of ignoring consent

Still tempted to take shortcuts? Consider this:

  1. You could face steep email marketing legal risks, including penalties under POPIA
  2. You’ll likely tank your domain’s sender reputation, hurting future email deliverability
  3. You risk damaging your brand’s trust and losing potential clients forever

In short: Don’t risk it. One wrong move in bulk emailing without proper consent can undo months of hard work.
