How to collect customer emails in your shop

Why your own list beats followers

Instagram and TikTok followers can disappear with an algorithm change or a hacked account. A list of customers' emails and phone numbers, collected with their permission, is yours. It lets you tell regulars about new stock, fill quiet days and bring back customers who drifted away, for very little money.

10 ways to collect emails and numbers

1. QR code at the counter: "Scan to get our offers and a birthday treat." The code opens your signup form.
2. Ask at checkout: a staff member types it into the form on the shop phone or tablet while the POS processes.
3. Receipts and invoices: a line with the form link or QR code.
4. Delivery packages: a small card in every parcel or food pack.
5. Social bios: the form link in Instagram, TikTok and WhatsApp Business profiles.
6. Website pop-up: if you have a website, an exit-intent pop-up offering a first-order discount.
7. Guest Wi-Fi sign-in: if you offer Wi-Fi, ask for an email on the sign-in page (with a consent box).
8. Events and pop-ups: a tablet with the form open, or a QR code on your banner, plus a giveaway draw.
9. Bookings: salons, clinics and caterers can ask for an email when confirming an appointment or order.
10. Loyalty card: "Join our list and your 10th haircut is free": the list is the loyalty card.

What to say

• "Would you like our new arrivals by email? We send one email a week, and you get a birthday surprise."
• "Can I send your receipt by email? I can also add you to our offers list if you like."
• "Scan this to join our VIP list: you'll hear about sales a day before everyone else."

Keep it light. Explain what they'll get and how often, and accept a no.

What to offer in return

Get consent right

Under the Nigeria Data Protection Act, people should know what they're signing up for. Your form should say who you are, what you'll send and how to unsubscribe, with separate tick boxes for email, SMS and WhatsApp if you'll use them. Don't pre-tick the boxes, and don't add people who only gave their number for a delivery. Double opt-in (a confirmation email) gives you the cleanest list.

Set up the form in ten minutes

In ENB, choose one of around 40 signup form templates, add your logo and the fields you want (name, email, phone, birthday), tick the consent options, and copy the link and QR code. New subscribers can get an automatic welcome email so they hear from you straight away. See contacts, forms and pop-ups.

What to do next

Send your new subscribers something within a day, while they remember you: a welcome email with what you sell, your best sellers and the promised offer. Then keep a steady rhythm. A list you never email goes cold fast.

Mistakes to avoid

• Pre-ticked consent boxes. Consent must be a clear choice.
• Asking for too much. Name and email (or phone) are enough to start; ask for a birthday only if you'll use it.
• A form that's hard to use on a phone. Test it on a cheap Android phone with weak network.
• Collecting and never sending. Send the first email within a day.
• Typing addresses in a notebook. Handwriting causes typos; let customers type their own on the form.

Track where signups come from

Create a separate form (or add a hidden field) for each source: counter QR code, Instagram bio, receipts, events. After a month, you'll know which sources bring the most subscribers, and which bring the customers who actually buy. Put more effort into those.

Key takeaways

• Ask at the moment of purchase, with a clear reason and a small benefit.
• Make it a ten-second QR code scan, not a notebook.
• Record consent for email, SMS and WhatsApp separately and never pre-tick boxes.
• Send a welcome message within a day while they remember you.
• Track which source brings subscribers who actually buy, and double down on it.
