Email marketing is deeply unfashionable. It has none of the excitement of social media or the immediacy of ads, and most business owners assume nobody reads newsletters any more. And yet, for repeat business and staying front of mind, it quietly keeps outperforming channels that get far more attention. Here's the honest version — what still works, what doesn't, and the UK rules you can't skip.
Where email still wins
A boiler service reminder a year after installation, a hairdresser nudging a client who hasn't booked in ten weeks, a landscaper announcing spring availability — these are exactly the situations where a short, well-timed email earns its keep, because it's reaching people who already know and trust the business.
Where it's dead
UK consent rules: PECR and GDPR
In practice that means: don't add every enquiry or invoice contact to a marketing list without telling them, always include a working unsubscribe link, and identify your business clearly in every email. Our guide to GDPR and cookie consent for small business websites covers the wider data protection picture your email list sits within.
Building a list honestly
Avoid buying lists or scraping addresses from directories. Beyond the legal risk, purchased lists produce terrible engagement and can get your sending domain flagged, which then damages every other email you send.
What to actually send, and how often
Useful content is usually simple: a seasonal reminder, a genuinely useful tip related to your trade, a short project or case study, availability for the coming weeks, or a modest offer for existing customers. Keep it short — most people skim on a phone, so a long newsletter gets abandoned before the useful part.
Deliverability basics
Beyond using a proper email marketing tool, deliverability depends on your domain having correctly configured SPF, DKIM and DMARC records, which authenticate that emails claiming to come from your domain are genuinely authorised to do so. Sending from a proper custom domain email address (rather than a generic free address) also matters for how trustworthy an email looks on arrival. Our guide to domain, DNS and hosting jargon explains what these records are and where to set them up; our managed hosting includes proper domain configuration as standard.
Tools, and measuring what actually matters
Open rates are worth watching but treat them with caution — privacy features in modern email clients inflate them artificially, so a reported 40% open rate may not mean what it used to. Click rate and, where relevant, reply rate are more honest measures of whether people are actually engaging, and booking or enquiry numbers in the days after a send are the real test of whether the list is worth the effort.
Common questions
Is email marketing still effective in 2026?
For repeat business, reminders and staying front of mind with past customers, yes. For cold acquisition it's largely dead — and in the UK, emailing people who haven't consented is illegal anyway.
How often should a small business email its list?
Monthly is a sensible default for most service businesses. Quarterly works if you genuinely have little to say. Weekly only if every email is worth opening.
What are the UK rules on marketing emails?
Under PECR and UK GDPR you generally need consent, or an existing customer relationship for similar products. Every email needs a working unsubscribe link and a clear sender identity.
Do I need a separate email marketing tool?
Yes. Sending bulk mail from your normal business inbox damages deliverability and skips the unsubscribe handling the law requires. Most small businesses fit comfortably in the free tier of a dedicated tool.
