Almost every South African business can run a newsletter, and almost none of them do it consistently. That gap is your opportunity. A simple, regular email keeps your brand in mind, drives repeat sales and costs next to nothing to run. Here is how to start properly.

Why should your business send an email newsletter?

A newsletter keeps you top of mind with people who already know you, which is the cheapest and most reliable way to drive repeat business. Social posts vanish in a feed and ads stop the moment you stop paying. A newsletter lands directly in an inbox you have permission to reach, and it builds a relationship over time. For a Johannesburg salon, a Durban restaurant or a Pretoria consultancy, that ongoing contact is what turns a one-time customer into a regular.

It also future-proofs your audience. Platforms change their algorithms and ad costs climb, but your email list is an asset you own outright.

Which newsletter platform should you choose in South Africa?

Choose a platform that matches your skill level and list size: Mailchimp and Brevo are the friendliest starting points, while Klaviyo suits stores wanting deeper automation. All three work well for South African senders. For a straightforward newsletter, Brevo and Mailchimp offer generous free tiers, simple drag-and-drop editors and built-in sign-up forms. If you sell online and want revenue tracking and segmentation, Klaviyo is worth the step up.

Whichever you pick, the platform must let you authenticate your sending domain. This single technical step protects your deliverability so your newsletter reaches inboxes rather than spam folders.

How do you build a POPIA-safe newsletter list?

Build your list on consent: use a clear sign-up form that tells people what they are subscribing to, and only add contacts who actively opt in. POPIA has been in force since July 2021 and is enforced by the Information Regulator, so permission and an easy opt-out are essential. Place a sign-up form on your website, link it from your email signature, and offer a small incentive such as a useful guide or a first-order discount.

Never buy a list or import addresses people did not give you. A small, consented list of engaged subscribers outperforms a large, cold one every time, and it keeps you on the right side of the law. This is general guidance and not legal advice.

How often should you send a newsletter?

For most South African small businesses, a fortnightly newsletter is the sweet spot: frequent enough to stay top of mind, rare enough to sustain quality. Weekly works for content-rich brands and online stores with regular promotions. Monthly is the minimum to remain memorable. The cadence you can keep up consistently beats an ambitious schedule you abandon after three sends.

Pick a day and stick to it. Predictability trains subscribers to expect and open your email, which lifts engagement and protects your sender reputation.

What should you write in a newsletter?

Lead with one genuinely useful idea, add a little brand personality, and finish with a single clear call to action. Useful might mean a tip, a behind-the-scenes story, a customer win or a timely offer. The mistake most businesses make is treating the newsletter as a pure sales blast. People unsubscribe from adverts; they stay for value.

Keep it short and scannable on mobile, since most South Africans read email on their phones. One idea, one action, a friendly tone. That formula is easy to repeat and easy to read.

How do you grow open rates over time?

Open rates are driven mostly by your subject line, sender name and list health, not the design inside the email. Write subject lines that promise something specific and worth the click, send from a recognisable name, and remove inactive subscribers periodically so your engaged audience stays strong. A clean, engaged list signals quality to inbox providers, which improves placement for everyone on it.

Test one thing at a time: a different subject line, a different send time, a different lead idea. Small, steady improvements add up to a newsletter that earns its keep.

Start simple. Choose a platform, add a sign-up form, write one valuable email, and send it. Then send the next one a fortnight later. Consistency, not complexity, is what makes a newsletter work in South Africa.
