Using Digital Receipts to Build Your Customer Email List

You have just served a first-time customer. They loved your coffee, praised your shop’s atmosphere, and paid with a quick tap of their card. They walk out the door, and the transaction is finished. But here is the problem: unless they decide to walk down your street again, you have absolutely no way to reach them.

For UK small businesses, the moments after a sale are critical. If you rely solely on paper receipts, you are quite literally printing money just to throw it in the bin.

According to recent 2025 retail data, the UK generates a staggering 11.2 billion paper receipts every single year. Most of these end up crumpled in pockets or thrown away because the thermal coating makes them impossible to recycle.

But the real waste isn't just the paper—it is the missed connection. By failing to capture a customer's email address at the till, you are ignoring one of the most profitable marketing channels available to your business.

The High Cost of the Paper Trail

Handing over a paper receipt might feel like standard practice, but it actively hurts your growth.

First, there is the literal cost. Till rolls are expensive, and constantly restocking them eats into your margins. Second, paper receipts give you zero data. You cannot tell what a customer bought last month, how often they visit, or what might tempt them to return on a quiet Tuesday afternoon.

Finally, your customers simply do not want them anymore. Recent surveys by Yocuda found that 71% of UK shoppers now choose a digital receipt when offered one in-store. If you do not offer a modern, paperless checkout, you look outdated.

The Solution: Your Card Machine as a Marketing Tool

Email marketing is far from dead. In fact, in the UK, the average return on investment (ROI) for email marketing is currently £38.33 for every £1 spent. In the retail and hospitality sectors, that return can jump even higher.

But how do you get people on your mailing list without forcing them to fill out a clipboard on the counter? You use your Teya card machine.

When a customer pays, our terminals can prompt them to receive their receipt via email or text. This simple interaction is the perfect bridge between an anonymous shopper and a loyal "Member" of your business community.

1. The Power of the Transactional Email

A digital receipt is a "transactional" email. Because the customer specifically asked for it to confirm their payment, it has an incredibly high open rate.

Industry data shows that receipt emails get up to 8 times more opens than standard marketing newsletters. When the customer opens that email to check their total, you have their undivided attention. You can use that space to say thank you, share your social media links, or offer a 10% discount on their next visit.

2. Effortless Building Customer Lists

Turning a one-off buyer into a regular requires a reliable system. When you capture an email at checkout, you can easily tie it into your digital loyalty programme.

Instead of a flimsy paper stamp card, their email becomes their identity. You can track their visits and automatically send them a reward when they hit a milestone. This makes building customer lists a frictionless part of your daily operations, rather than an awkward sales pitch.

3. Staying on the Right Side of the Rules

When you collect email addresses, you must follow the rules set by the Information Commissioner's Office (ICO). Thankfully, the UK’s GDPR framework includes something called the "soft opt-in".

This means you can send marketing emails to existing customers if:

• They bought something from you (or negotiated a sale).

• You are marketing similar products or services.

• You gave them a clear, simple way to opt out when you took their email, and in every message since.

Always be transparent. When asking for their email for the receipt, simply ask: "Can we also send you our weekly specials?" ### 4. Meeting Demand for Eco-Friendly Receipts Sustainability is a massive driver of consumer behaviour. Shoppers know that thermal receipt paper contains chemicals that cannot go in the recycling bin.

By offering eco-friendly receipts, you show your community that you care about your local environment. It is a small change, but it aligns your business with the values of modern UK consumers. Over 85% of shoppers expect to see fewer or no paper receipts in the next few years.

5. Leveraging Customer Data Insights

Once you have an active email list tied to your transaction history, you stop guessing and start knowing.

You can use customer data insights to segment your audience. If you run a pub and you know a specific group of customers always buys your Sunday Roast, you can email them on Thursday to take table bookings. Targeted, relevant emails feel like heartwarming hospitality, not spam.
