How much does email marketing cost for a UK small business?
Running email marketing yourself costs £0 to about £60 a month in the UK: free plans cover very small lists (Mailchimp’s and MailerLite’s both stop at 250 contacts), and paid plans run roughly £10 to £60 a month for typical small-business lists. An agency running it for you typically charges £500 to £5,000 a month on a retainer, with freelancers and smaller agencies from about £300 a month. In between sits a one-off setup: ours is £149, and you send the campaigns yourself.
| Route | Typical UK cost | What you get |
|---|---|---|
| Free plan | £0 | Up to 250 contacts on Mailchimp or MailerLite, up to 10,000 subscribers on Kit, with limits on sends and features |
| Paid platform, DIY | About £10 to £60 a month | Automations and no platform branding; you write and send |
| One-off setup | £149 with us | Templates, welcome and follow-up automations and segments built once; you send the campaigns |
| Freelancer | From about £300 a month | Campaigns written and sent for you |
| Agency retainer | About £500 to £5,000 a month | Strategy, writing, sending, automations and reporting |

The three costs hiding in “email is basically free”
Email’s reputation as the highest-ROI channel is deserved, but the “free” framing misleads. There are three separate costs:
- The platform: the smallest cost. Priced by list size, from £0 to a few tens of pounds monthly for most small businesses.
- The time: the real cost of DIY. A decent monthly campaign takes 2 to 4 hours to plan, write, build and check; automations take longer to set up well. At any sensible value on your time, this dwarfs the platform fee.
- The skill, invisible until it bites. Subject lines that get opened, sends that dodge the spam folder, automations that trigger at the right moment, and staying on the right side of UK marketing-consent rules all have learning curves that show up as flat results in months one to six.
Most “email doesn’t work for us” stories are really “we paid for a platform and never budgeted the time or skill” stories. Decide which of the three you are buying before comparing prices.
Platform costs in 2026: Mailchimp vs MailerLite tiers
| List size | MailerLite (approx.) | Mailchimp (approx.) | Notes |
|---|---|---|---|
| Up to 250 subscribers | Free plan (up to 2,500 emails a month) | Free plan (up to 250 contacts) | Free plans carry branding and hold back features; limits checked October 2026 |
| ~1,000 subscribers | £10 to £15/mo | £15 to £25/mo | Entry paid tiers unlock automations and remove branding |
| ~5,000 subscribers | £25 to £40/mo | £50 to £80/mo | The gap between platforms widens with list size |
| ~10,000 subscribers | £40 to £70/mo | £80 to £120/mo | At this size, deliverability and segmentation matter more than price |
Prices are typical UK rates at the time of writing. Both platforms price in tiers and change them periodically, so check the pricing pages linked below before committing. Two buying notes: platforms charge for every contact, so cleaning dead subscribers off your list is a genuine cost-saver; and switching platforms later is workable but tedious, so pick for the automation features you will want in year two, not just the month-one price.
DIY vs managed: the honest comparison
| DIY on a platform | Managed service (agency retainer) | |
|---|---|---|
| Monthly cost | £0 to £60 platform fee | Typically £500 to £5,000 a month for strategy and execution (freelancers from about £300), plus the platform fee |
| Your time | 2 to 4+ hours per campaign, more for automations | Roughly an hour to review and approve |
| Consistency | The first casualty of a busy month, and consistency is what makes email work | Contracted: campaigns go out whether you are busy or not |
| Automations | Usually a welcome email, if anything | Welcome series, follow-ups, win-back campaigns for lapsed customers |
| Copy & design | Your writing, template designs | Professionally written and branded |
| Compliance | Your responsibility to learn | Consent, unsubscribe handling and UK rules managed for you |
The crossover is simple: DIY wins while your list is small and your diary has slack. The managed route earns its fee when campaigns keep not going out, or when your list has grown past the point where amateur segmentation leaves money on the table.
How email marketing agencies price their work
Agency quotes for email marketing are hard to compare because they are built on different models. Most use one of four, or a mix:
| Pricing model | What you pay for | Suits | Ask before signing |
|---|---|---|---|
| One-off setup | Platform setup, templates, automations and segments, built once | Businesses that will send their own campaigns afterwards | Which automations are built, and whether you get a written guide to them |
| Per campaign | Each newsletter or offer, written, built and sent | Seasonal senders with a few campaigns a year | Whether writing, design and segmentation are all in the price |
| Monthly retainer | A set number of campaigns a month, plus automation upkeep and reporting | Businesses that want email to go out every month without fail | How many sends are included, and the notice period |
| Share of email revenue | A percentage of the sales attributed to email, sometimes on top of a base fee | Larger online shops with clean sales tracking | How attribution is measured, because that count sets the fee |
Whatever the model, two things should never be negotiable: the email platform account is in your name and paid by you, and the subscriber list belongs to you. An agency that keeps your list inside its own account makes leaving expensive, and a list is the one marketing asset a small business owns outright.
Worked example: a year of email marketing for a small UK business
Take a business with about 1,000 subscribers, mostly past customers, that wants a monthly newsletter and the three core automations. Using the platform prices in the table above:
- Fully DIY: £10 to £25 a month on a platform, so £120 to £300 a year, plus 2 to 4 hours for each of twelve campaigns, which is 24 to 48 hours of your time. The automations happen only if you build them yourself.
- Setup done for you, campaigns DIY: our £149 setup, paid once, plus the same £120 to £300 a year for the platform. Year one comes to £269 to £449, the automations run from the first week, and your time goes on the monthly newsletter only.
- Everything managed: the platform fee plus a retainer, which is where agency pricing varies most. Ongoing campaign writing and sending from us is quoted in writing before any work starts.
For most small businesses the middle route is the sensible start: the automations are the part that earns without anyone remembering to send, and the hardest part to build well without experience. If you have not started a list yet, email marketing for small businesses covers the first steps, and if your business emails already land in junk, fix the spam problem before sending more. Every price is on our price list.
What ROI should a small business actually expect?
Industry lore says email returns many multiples of its cost, and for small businesses the mechanics genuinely favour it: you are writing to people who already know you, at near-zero marginal cost per send. But the return depends almost entirely on who is on the list. Realistic expectations:
- Past customers are the goldmine. A monthly email with recent work, a seasonal reminder or a referral nudge to people who have already bought from you routinely beats any cold channel per pound spent. If you hold hundreds of dormant customer emails, that dormant list is probably your single cheapest source of new revenue.
- Cold lists are a trap. Bought lists perform terribly, poison your sender reputation, and breach UK consent rules. Never worth it at any price.
- Judge it over quarters, not sends. One campaign proves little; a consistent cadence compounds. Track replies, clicks and, above all, enquiries or orders attributed to email each month.
Email also amplifies everything else: it is the cheapest line in the small-business marketing budget, and the channel that keeps paying after ad spend stops.
When email is the wrong priority
- You have no list and no way to build one. Fix capture first (a signup incentive on the website, an email field in the checkout) or there is nothing to send to.
- The website doesn’t convert. Email drives people somewhere; if that somewhere leaks, fix the destination before the traffic.
- You’d be emailing without consent. UK direct-marketing rules require it, and shortcuts cost more than they return.

It slots alongside whatever else you run; see what UK marketing agencies charge for how that compares across the board. We have delivered branding, print and web projects for UK businesses since 2019, rated 4.8/5.
Building the list legally: the PECR rules in plain English
UK email marketing is governed by PECR alongside GDPR, and the rules are simpler than the acronyms suggest. You can email people who opted in (ticked an un-pre-ticked box, signed up to your newsletter), and you can email existing customers about your own similar products under the “soft opt-in”, provided you offered an opt-out when you collected the address and every email carries a working unsubscribe. What you cannot do: email a purchased list, scrape addresses, or keep emailing after an unsubscribe. Fines are real but the bigger cost is deliverability: spam complaints train inbox providers to bury everything you send.
Practical implications: put a signup on your website with a plain-English promise (“occasional offers and useful guides, no spam”), collect addresses at the point of sale with the opt-out visible, and honour unsubscribes instantly and permanently. That’s the entire compliance burden for a small business: an afternoon of setup.
The first three automations worth paying for
Broadcast newsletters get the attention, but automations do the earning, because they run on triggers, not calendar discipline:
| Automation | Trigger | Why it pays |
|---|---|---|
| Welcome series (2 to 3 emails) | New signup | Highest open rates you will ever see; sets expectations and makes the first offer |
| Post-purchase follow-up | Order completed | Review request + care instructions + the natural next service (retention on autopilot) |
| Win-back | No order in 6 to 12 months | Reaching past customers costs pennies against acquiring strangers |
All three exist as templates in every mainstream platform; a managed service earns its fee by writing them properly, wiring the triggers to your store, and watching the numbers monthly. If budget forces a choice, automate first and broadcast later, and fold the spend into a marketing budget you actually track.

Frequently asked questions
How much does email marketing cost for a UK small business? +
In 2026: free plans cover very small lists (Mailchimp's and MailerLite's both stop at 250 contacts), and paid platform plans run about £10 to £60/month for typical small-business lists. Fully managed email marketing (strategy, writing, sending and automation) from an agency typically costs £500 to £5,000/month on a retainer, with freelancers and smaller agencies from about £300/month. A one-off setup, such as our £149 email marketing setup, is the middle route if you will send the campaigns yourself.
Is Mailchimp or MailerLite cheaper? +
MailerLite is typically cheaper at every list size, roughly £10 to £15/month at 1,000 subscribers versus £15 to £25 for Mailchimp, with the gap widening as lists grow. Both change tier pricing periodically, so check their pricing pages before committing.
What ROI does email marketing give small businesses? +
Email is usually the highest-return channel because you are contacting people who already know you at near-zero cost per send. Returns depend on list quality: past customers respond best, bought cold lists perform terribly and breach UK consent rules. Judge results over a quarter of consistent sending, not one campaign.
Should I do email marketing myself or pay an agency? +
DIY makes sense while your list is small and you can reliably spend 2 to 4 hours per campaign. A managed retainer, typically £500 to £5,000/month from an agency, earns its fee when campaigns keep not going out, when automations are beyond your setup skills, or when a grown list needs proper segmentation. If the setup is the only hurdle, a one-off setup (ours is £149) builds the automations and leaves the sending to you.
Do I need permission to send marketing emails in the UK? +
Yes. UK direct-marketing rules require consent (or an existing-customer relationship with an easy opt-out for similar products), and every email must include a working unsubscribe. Bought lists fail both tests and damage your sender reputation.
