Email marketing for small businesses in Ireland
Social media reach rises and falls with every change to the platforms. An email list is different: it belongs to your business, it reaches people who asked to hear from you, and it costs very little to run.
For a café, a shop, a gym or a trades business, email does not need to be complicated. A short, useful message once or twice a month, sent to people who want it, will keep you in mind when they next need what you sell. This guide covers the practical side. Before you send anything, read GDPR and email marketing in Ireland for the rules on who you can email.
Choosing an email platform
Do not send marketing emails from your ordinary inbox by putting everyone in BCC. A dedicated email marketing platform handles sign-up forms, unsubscribes, consent records and sending at volume, and gives you reports. When comparing platforms, look at:
- Price at your list size, including what happens as the list grows.
- Sign-up forms you can embed on your website and link to from your Google Business Profile and social media.
- Automation, at least a welcome email for new subscribers.
- Integration with your online shop or booking system.
- Data protection: where data is stored and whether the provider offers a data processing agreement, which you need under the GDPR.
Building your list
Quality matters more than size. A few hundred local customers who open your emails are worth far more than thousands of addresses that never engage. Good ways to grow a list include:
- A sign-up form on your website, with a clear promise of what people will get.
- An unticked marketing opt-in box at online checkout or booking.
- A sign-up sheet or tablet at the counter or at events, worded clearly.
- Links from your social media profiles and posts.
Whatever the method, people must know they are signing up for marketing, and you must keep a record of it.
What to send
The best small business emails are useful or interesting first and promotional second. Ideas that work for most businesses:
- What is new: products, menus, services, timetables.
- Seasonal information: Christmas opening hours, bank holiday arrangements, summer timetables.
- Useful advice drawn from your expertise. A garden centre can send what to plant this month; a garage can send a winter car check.
- Behind the scenes: new staff (with their consent), a new supplier, a refurbishment.
- Occasional offers for subscribers.
Keep each email focused on one main message with one clear action: book, buy, call, visit.
How often to send
Consistency matters more than frequency. For most small businesses, once or twice a month is manageable and enough to stay in mind. Tell people at sign-up how often to expect emails, then stick to it. If you have nothing worth saying, skip a send rather than filling space.
Writing emails people open
- Subject line: say what is inside, plainly. "Christmas opening hours and our new winter menu" beats a clever pun.
- Sender name: use your business name, or a recognisable person at the business.
- Write for phones: short paragraphs, a single column, buttons big enough to tap.
- Images: use them, but make sure the email still makes sense if images do not load, and add alt text.
- Tone: write the way you would talk to a regular customer at the counter.
Staying out of the spam folder
Deliverability, whether your email reaches the inbox, depends partly on technical settings. Since 2024, Google and Yahoo have required bulk senders to authenticate their email, and good practice applies to small senders too:
- Send from your own domain (an address at yourbusiness.ie rather than a free webmail account).
- Set up SPF, DKIM and DMARC records for your domain. Your email platform will give you the records to add; your web host or domain provider can help.
- Make unsubscribing easy. If people cannot unsubscribe, they mark you as spam, which damages delivery for everyone on your list.
- Clean your list. Remove addresses that bounce and consider removing people who have not opened anything in a long time.
Which numbers to watch
| Measure | What it tells you |
|---|---|
| Clicks and click rate | Whether people acted on the email. The most reliable engagement number. |
| Open rate | A rough guide only. Privacy features in some email apps, such as Apple Mail, register opens automatically, so open rates can be overstated. |
| Unsubscribes | A spike after a particular email tells you something about that email. |
| Bounces and spam complaints | Signs of list quality or deliverability problems. |
| Sales or bookings | What actually matters. Use tracked links or a subscriber-only code to see what email brings in. |
A simple starting plan
- Pick a platform and set up your domain authentication.
- Add a sign-up form to your website with clear wording and a privacy notice link.
- Write a welcome email that goes out automatically to new subscribers.
- Plan a monthly email for the next three months, tied to what is happening in your business. Our social media plan guide has a planning method that works for email too.
- Review clicks and sales after three months and adjust.
Frequently asked questions
How often should a small business send marketing emails?
For most small businesses, once or twice a month is enough. Tell subscribers how often to expect emails and stay consistent.
Can I send marketing emails from Gmail or Outlook?
Not for a list. Use an email marketing platform that manages sign-ups, unsubscribes and consent records, and send from your own business domain.
What are SPF, DKIM and DMARC?
They are DNS records that prove emails sent in your domain's name are genuine. Major mailbox providers expect them, and they help your emails reach the inbox.
Are open rates reliable?
Only roughly. Some email apps register opens automatically for privacy reasons, so clicks and sales are better measures of success.
