You have decided to try email. Maybe a customer asked whether you send offers, maybe a competitor’s newsletter keeps landing in your own inbox, or maybe you looked at the pile of customer addresses in your order history and thought it was a waste to leave them sitting there. The hard part is not wanting to do it. The hard part is knowing what to do first.
This guide sets out email marketing for small business in the order the pieces depend on each other: who you can write to, what you send it with, how you stop it landing in spam, what to send, what to automate and how to judge whether it is paying off. Each step links to a narrower guide if you want the detail.
Where email marketing for small business earns its place
Email is a channel for people who already know you. It will not find you new customers the way search or ads can. What it does well is bring people back: the customer who bought once and might buy again, the enquiry that went quiet, the person who liked your advice and wants more of it.
That makes it a strong fit for some businesses and a weak one for others.
- Good fit: repeat purchases (a bakery, a pet supplies shop, a salon), seasonal work (servicing before summer, admissions before the school year), businesses with useful advice to share (a physiotherapist, an accountant), and online stores of almost any kind.
- Weaker fit: one-off purchases many years apart, or a business that genuinely has nothing new to say for months at a time.
Even in the weaker cases, a short email at the right moment of the year can be worth sending. The question is whether you can keep up a pace, not whether email is fashionable. If you run a local shop or service and want a gentler introduction, our piece on running a newsletter for a local business covers whether a regular email is right for you.
How to start email marketing: the order matters
Most small businesses start in the middle. They write a newsletter, paste every address they can find into the BCC field, press send, and then wonder why half of it bounced and some of it went to spam. Doing the steps in order avoids that.
- Gather a list of people who opted in to your emails.
- Pick a sending platform and open the account in your business’s name.
- Authenticate your domain on that platform before the first send.
- Write and send a few plain, useful newsletters.
- Add one automation, usually a welcome email.
- Decide which numbers you will judge it by, and look at them monthly.
Each of those is covered below in a few paragraphs.
Step one: a list of people who asked
The list is the whole asset. Everything else can be changed later; a list built badly is hard to fix. The rule is simple to say and easy to break: only add people who chose to receive marketing email from you.
Places to ask include a short signup form on your website, an unticked box at checkout or on a booking form, a sheet or tablet at the counter, and a link on receipts. Our guide on how to grow an email list from scratch goes through each of those, with wording that tells people what they will get.
Two things to avoid from the start:
- Buying or scraping addresses. The people on those lists do not know you, many of the addresses are dead or are traps set to catch spammers, and sending to them can damage your domain for every email you send afterwards, including invoices.
- Importing everyone who ever contacted you. An enquiry or a purchase is not agreement to receive newsletters. From an old spreadsheet, keep only those you are confident agreed.
Consent has legal weight in many countries as well as practical weight. Our overview of consent and unsubscribe duties sets out the broad rules for India, the EU and UK, and the US, without pretending to be legal advice.
Step two: a sending platform in your business’s name
Newsletters should go out through a dedicated email marketing platform, not your normal mailbox and not your website’s hosting server. A platform handles unsubscribes automatically, removes addresses that bounce, gives you templates that work on phones, and shows you who clicked what.
There are plenty of reasonable choices. What matters more than the brand is that it suits how you work: whether it connects to your shop or booking system, whether the automations you need come with the plan you would actually be on, and whether you can export your list and consent records if you leave. We have written up what to compare between email platforms in neutral terms.
Whatever you pick, open the account with a business email address you control, as the owner. If someone helps you, add them as a user. An account in a freelancer’s or former employee’s name is a list you may lose.
Step three: authenticate the domain before the first send
This is the step most first-time senders skip, and it is the one that most decides whether emails arrive. Receiving mail servers check whether a message claiming to come from your domain was really sent with your permission. They do that by looking up records in your domain’s DNS.
- SPF lists the services allowed to send for your domain.
- DKIM signs each message so the receiving server can confirm it was not altered or forged.
- DMARC publishes your instruction for mail that fails both, and ties the result to the From address the reader sees.
Your platform will show the exact records to add. The common mistake is creating a second SPF record for the platform instead of adding it to the existing one, which can break SPF for your everyday mail as well. Large providers such as Gmail and Yahoo now expect authenticated mail and easy unsubscribing from anyone sending in volume. If your newsletters are already arriving in spam folders, start with our checklist for emails that land in junk folders.
A note on scope: setting up your office mailboxes on the domain is a separate job from email marketing, though the two share DNS records. If that side is not done yet, our business email setup page covers it.
Step four: your first few newsletters
A first newsletter does not need a designer. It needs one clear reason to exist. A new service, a change of hours, a seasonal reminder, a useful tip from your trade, a real offer with its real end date. Pick one main point per email and make it easy to act on.
A few habits that help from the first send:
- Put a sender name people will recognise at a glance, usually the shop or practice name.
- Write a subject line that says what is inside, rather than one that tries to be clever.
- Keep it mostly text, with short paragraphs and one obvious link or button.
- Use a reply-to address someone reads. Replies are valuable.
- Send a test to yourself and look at it on your phone before sending to everyone.
Pick a pace you can keep. Regular and modest beats ambitious and abandoned. Three issues followed by a year of silence teaches subscribers to ignore you, and the next email after the gap is likely to draw complaints from people who forgot they signed up.
Once the list grows, you may not want every subscriber to get every email. Customers and people who have only enquired often want different things. Our page on splitting your list into simple groups shows how to do that without building something complicated.
Step five: one automation that runs without you
Automated emails are sent by the platform when something happens: someone joins, buys, books or goes quiet. They are written once and keep working in weeks when nobody has time to write a newsletter.
Start with one. For most businesses that is the welcome email, because the person has just asked to hear from you and is more likely to read it than anything you send later. It should deliver whatever the signup form promised, say briefly who you are, and set expectations about what comes next. Our guide to writing a short welcome series has a simple three-email outline.
After that, consider a thank-you and how-to-use email after purchase, a reminder when a service is due again, or a polite review request. Each is described in our overview of automated emails a small business can use. For online stores, cart reminders are worth having too, once the checkout itself works well.
Whatever you automate, check it every few months. Automations go stale quietly: an old phone number, a product you no longer sell, a link to a page that has moved.
Step six: measuring what matters
Your platform’s dashboard will lead with the open rate. Treat it loosely. Some mail apps load images automatically for privacy reasons, which registers an open whether or not anyone read the email, and others block the tracking altogether.
The signals worth trusting more are:
- Clicks, and which links got them.
- Replies, which tell you what people think in their own words.
- Enquiries, bookings and orders that followed, which you can see in your website analytics if each link carries campaign tags.
- Unsubscribes and spam complaints, the clearest warning that the pace or the content is off.
- List growth, and which signup point it came from.
Our guide to the email numbers worth tracking explains each one and suggests a one-page monthly summary. Judge over several sends rather than one. A single quiet newsletter tells you little; a steady pattern over months tells you a lot.
The rest of this email series, by task

- Re-engagement: asking quiet subscribers whether they still want your emails.
- The requirements large mailbox providers now set for bulk senders.
- Designing emails that read well on a phone, and when plain text is better.
- The difference between order emails and newsletters, and why they should be sent separately.
- Email for WooCommerce stores: syncing customers with consent and post-purchase emails.
Email is one channel among several. Our overview of online marketing services shows where it sits alongside search, ads, social and WhatsApp.
Frequently asked questions
Can I start email marketing with only a few dozen subscribers?
Yes. A small list of people who know you and chose to join is a perfectly good start, and it is easier to learn on. Write to them as you would to a few regular customers, watch the replies and clicks, and let the list grow from your signup points rather than rushing to make it bigger.
Should newsletters come from the same address as my everyday business mail?
They can come from the same domain, but use a recognisable address such as news@ or a named person, set as the sender inside your marketing platform. Avoid sending newsletters from your personal mailbox itself. Some businesses use a subdomain for marketing to keep its reputation slightly apart from invoices and quotes.
Is email worth doing if most of my customers use WhatsApp?
Often, yes, because the two do different jobs. WhatsApp suits short, timely notices and conversations. Email suits longer updates, tips, links and anything people may want to find again later. Consent is collected separately for each, so ask customers which they prefer rather than assuming one list covers both.
What is the most common mistake when a business starts sending newsletters?
Sending to everyone it has ever had an address for, from a normal mailbox, without authenticating the domain. That combination brings bounces, spam complaints and a damaged sending reputation in one go. Starting with a consented list on a proper platform, with SPF, DKIM and DMARC in place, avoids most early trouble.
If you would rather have the setup done properly and keep the writing yourself, or hand over the whole monthly cycle, our email marketing services page explains how we work and what stays in your name.
