Kemi woke up on a Monday to a message from Instagram, her account had been suspended.
Four years of posts, 23,000 followers, every customer who ever sent her a DM asking “how much for the red velvet?”
She hadn’t broken any rule she knew of, so she appealed, and Instagram replied the way NEPA replies when you complain about light.
By Wednesday she was begging her friends to repost her new page, starting from zero like a JSS1 student on resumption day.
I tell this story because most Nigerian businesses are one bad Monday away from being Kemi. If Instagram shut your account tomorrow, most businesses would be left with a phone full of contacts saved as “Lekki Customer 2” and “Aunty Cake”.
You’ve been building your house on rented land, and the landlord doesn’t even know your name.
An email list is the one audience you own. It survives suspensions, algorithm changes and the slow death of whatever app is fashionable this year. It’s also attached to the highest-ROI channel in marketing, which is a nice bonus for something you own outright.
Our deliverability guide covers keeping your emails out of spam. This one is about getting the list in the first place, from zero, without landing yourself in trouble.
Instagram’s rules work like the commandments on the barn wall in Orwell’s Animal Farm. They get quietly repainted overnight, and everyone is told they always said that. An email list runs on rules you wrote yourself.
Please Don’t Buy a List
Sooner or later, someone on a WhatsApp group will offer you “50,000 verified Lagos emails, very cheap.”
Say no. Then consider leaving the group.
Bought lists are unlawful under the NDPA, because those people never agreed to hear from you. They wreck the sender reputation your real emails depend on. And they don’t even work. Strangers who never asked to hear from you mark you as spam and move on with their lives.
The number that matters is how many people chose to hear from you. I’d take five hundred of those over ten thousand scraped addresses every single time.
Keep a record of each person’s consent in your CRM, with when they signed up, where, and what they agreed to receive. That record is what makes the list legal, and it’s what makes it worth something.
Nobody Wakes Up Wanting Your Newsletter
“Subscribe to our newsletter” is where signup forms go to die.
Look at it from the other side. Your customer’s inbox is already full of bank alerts, promo codes from apps they used once, and an uncle forwarding chain messages about the end of the world. Nobody is out looking for one more email.
People hand over their address when they get something worth more than the annoyance they’re signing up for. For Nigerian audiences, these work best, roughly in order of pull.
- A useful resource, such as a price guide, a checklist, a template or a calculator that answers the question they were already asking.
- First dibs on new stock, early booking or member pricing.
- A discount or bonus on the first order. It works, but it also pulls in people who only ever buy on discount, so watch who it brings.
- A preview of what they’ll actually get. Show them a real past email. Nobody has ever signed up for “updates”.
Before you use any lead magnet, ask yourself whether a real customer would thank you for it even if they never bought anything. If they would, it’ll attract the right people. If they wouldn’t, it’s bait, and bait attracts the wrong fish.
It’s the same logic behind the free diagnostic on this site, by the way. I give it away because it’s useful on its own. If it weren’t, nobody would bother filling it in.
Put the Door Where People Already Walk
Most businesses hide their signup form in the footer, next to the copyright line, where nobody in history has ever looked.
Put it where people already are.
On your website, offer something at the moment someone is interested, such as a related resource inside an article, the relevant guide on a service page, or the price list at the enquiry form. Keep the form short, because fewer fields win, and go easy on the pop-ups.
At the sale itself. This is the best signup moment you’ll ever get, because the customer has just trusted you with their money. Add a clear, unticked box at payment or delivery that says “Send me offers and updates.” Do it every time and you’ll end up with a list made entirely of buyers, which is the most valuable list there is.
On social, on purpose. Instagram and TikTok are where people meet you, and your list is where they stay. Use the link in your bio, your stories and your pinned post to move people from rented reach to an audience you own.
On WhatsApp and offline. Put a QR code at the counter and on your delivery packaging. After each delivery, send a quick WhatsApp message asking if they’d like your monthly offers by email. At events, collect signups on a tablet, because nobody has ever typed up the paper sign-up sheet. If someone agrees out loud, tag it in your CRM. Spoken consent still needs a record.
Do the maths. A list that grows by 150 real subscribers a month reaches 1,800 in a year. Say 2% of them buy in a given month. That is an assumption, so swap in your own rate. It means 36 orders, and at a ₦30,000 average order that is ₦1,080,000 a month from people you can reach whenever you like. Social can’t promise you that, because organic reach on Facebook now sits at roughly 1 to 2% of followers. A list built on consent can out-earn a far bigger following. It grows slowly, and it keeps growing. I’ll take that over one viral week.
Where Most Lists Go to Die
Most lists die after the signup.
Someone joins, the welcome email never comes, and six months of silence go by. Then one random Tuesday, a “MEGA SALE” email lands from a business they’ve completely forgotten, and they hit “report spam”.
Three habits stop this from happening to you.
Send the welcome straight away. It’s usually the most-opened email you’ll ever send, so use it well. Tell people what they’ll get from you and how often.
Keep the rhythm you promised. Send too often and people unsubscribe. Disappear for six months and they forget you exist, which is worse.
Tag people from day one. Even two tags help, like customer or prospect, or interest A or interest B. Then you can send the right emails to the right people, and that relevance is where email’s famous returns come from. Use double opt-in on digital signups to keep the list clean and your consent trail airtight.
Start This Month
Pick one lead magnet worth an email address. Offer it in two places, at the point of sale and on WhatsApp. Record consent every time, and send the welcome email the same day someone joins.
Do that for a year and you’ll own an audience no platform can switch off.
By Monday Afternoon
Kemi is rebuilding her page one follower at a time. If even 2,000 of her customers had been on an email list, she could have told them where to find her by Monday afternoon, before her competitors noticed she was gone.
The free 2-minute diagnostic will tell you whether retention is your weakest wall, or whether something else needs fixing first. Your result arrives on screen and by email, which, fittingly, is one email you’ll actually want.
P.S. If your business spends ₦1M or more a month on marketing, you also qualify for a free Leak Check. It’s a 30-minute call on three places your money is leaking, and nobody will add you to a list you didn’t ask to join.
Kemi’s story is illustrative. Performance figures referenced (email ROI, welcome-email open rates, organic-reach benchmarks) are detailed and sourced in the linked guides, current as of mid-2026, and vary by list quality and industry. Consent requirements are governed by the Nigeria Data Protection Act 2023. This article is general information, not legal advice.
