How should a small online shop do email marketing?

Why email matters for a small shop

Search rankings change, social media reach rises and falls, and marketplaces decide who sees your listings. Your email list is different: it is a list of people who asked to hear from you, and you can reach them whenever you have something worth saying. For a small shop with loyal customers, it is often the cheapest way to turn one order into several.

The flip side is that it only works if people trust you. That means collecting addresses properly, sending things they value and making leaving easy.

Consent: the rules in plain terms

In the UK, marketing emails to individuals are covered by the Privacy and Electronic Communications Regulations (PECR), alongside UK data protection law. The Information Commissioner's Office (ico.org.uk) publishes guidance for businesses, and you should read it or speak to an adviser for your own situation. The general position is:

• You normally need consent to send marketing emails to individuals. Consent must be freely given and specific, which means an unticked box or a clear sign-up action, not a pre-ticked box hidden in the checkout.
• There is an exception for existing customers, often called the soft opt-in. Broadly, if you got someone's email address during a sale, you may market your own similar products to them, as long as you gave them a clear chance to opt out when you collected the address and in every message after.
• Every email must identify you and include an easy way to unsubscribe, which you must honour promptly.
• Keep records of how and when each person signed up.

The soft opt-in has conditions and does not cover everything, for example it does not let you share the list with another business. Check the ICO's current guidance before relying on it. If you also sell into the EU, the rules in each country can differ; see our guide to selling to the EU from the UK.

Growing the list honestly

Places to collect sign-ups without annoying visitors:

• a checkbox at checkout, unticked by default, with a short line about what you will send
• a simple form in the footer and on the "About" page
• a back-in-stock alert on sold out products, which also tells you which items people want
• a sign-up card in parcels pointing to your website
• a pop-up, if you use one, that waits until a visitor has scrolled or spent some time on the page, and is easy to close on mobile

Say what people will get and how often. "New products and the occasional offer, about twice a month" sets an expectation you can keep. A first-order discount works for many shops, but it can train customers to wait for codes, so consider alternatives such as free delivery or early access to new ranges.

The automatic emails worth setting up first

Automated flows run in the background and are triggered by what a customer does. Start with these and add more only when they are working.

1. Welcome series

Sent when someone joins the list. Two or three emails over a week or so:

1. Thank them, deliver anything you promised, and say what to expect.
2. Tell the story of the shop: who makes or chooses the products, and why.
3. Point them to best sellers or the most useful guides, with one clear link.

2. Abandoned basket

A reminder to shoppers who started checkout but did not finish. It needs the right consent basis and a careful tone; our guide to abandoned cart recovery covers timing and wording.

3. Post-purchase

After delivery, send care instructions or tips for using the product, and later a request for a review. This is service first and marketing second, and it is where loyal customers are made.

4. Win-back

For customers who have not ordered in a long time, a short note with what is new. If they still do not engage after a while, consider removing them, which keeps your list healthy.

What to send each month

Beyond automations, most small shops do well with one or two regular emails a month. Ideas that do not depend on discounts:

• new arrivals, with real photos and a sentence about each
• a seasonal edit: gift ideas, summer range, back to school
• how-to content: caring for, styling, using or choosing your products
• behind the scenes: a new supplier, a workshop, a packaging change
• restocks of popular items
• honest news: delivery cut-off dates before holidays, price changes, new payment options

Keep each email focused on one main idea with one main button. Write a subject line that says what is inside rather than trying to be clever. Check every email on a phone before sending, since that is where most people will read it.

Choosing a tool and keeping data tidy

Dedicated email platforms connect to WooCommerce through plugins and sync customers and orders, so you can send to "customers who bought candles" rather than everyone. Pricing usually depends on the number of contacts or emails sent, and some offer a free tier for small lists. Check their current pricing pages and make sure they sync unsubscribes both ways. A few practical points:

• Authenticate your sending domain (SPF, DKIM and DMARC records). Your email platform will show you which records to add, and it helps your emails reach inboxes rather than spam folders.
• Do not buy or import lists of people who did not sign up with you.
• Remove addresses that bounce repeatedly.

Replies to marketing emails are often order questions in disguise. On Shop Grow at Retail Web Hosting, BonusFlow Ecommerce shows orders, returns and order questions next to each customer's email, so whoever answers can see the full picture before replying.

Measuring what works

Open rates are less reliable than they used to be, because some email apps load images automatically and count as an open. Pay more attention to clicks, orders attributed to each email, unsubscribes and spam complaints. Compare each send with your own previous sends rather than with published averages, and change one thing at a time: subject line, send day, layout or offer. Over a few months, you will know what your customers respond to, which is worth more than any general benchmark.
