How Much Does Email Marketing Cost in the UK?

Email marketing in the UK costs anything from £0 to several thousand pounds a month. A small list can run on a free plan, entry-level paid platforms start at around £6 to £15 a month, a marketing executive costs £23,000 to £50,000 a year, and outsourced management at ProntX starts from £450 a month plus your platform fee.

The honest answer to how much email marketing costs is that the software is the cheap part. What you really pay for is the time to plan, write, design, test and report on emails, and the setup work that gets them into the inbox. This article breaks the cost into its parts, shows current platform prices as of October 2026, and gives you a simple way to decide between doing it yourself, hiring, or outsourcing.

Key takeaways

• Platform fees are small at the start. Mailchimp, Klaviyo and Brevo all have free plans, and Brevo’s paid Starter plan is listed at £6 a month on monthly billing.
• Time is the biggest cost. Each campaign needs planning, copy, design, testing and reporting, whoever does it.
• Prices rise with your list. Some platforms charge by contacts, others by emails sent, so the same list can cost very different amounts.
• Setup has a cost too: domain authentication, sign-up forms, automated flows and integrations with your shop or CRM.
• UK law shapes the budget. Bought-in lists cannot be mailed under the soft opt-in, so list growth has to be earned.

How much does email marketing cost in the UK?

For most UK small businesses, email marketing costs between nothing and a few hundred pounds a month in software, plus the cost of someone’s time. The total depends on three things: how many contacts you have, how often you send, and who does the work.

It helps to split the bill into four parts. Most quotes you see online only cover one of them, which is why prices look so inconsistent.

How much do email marketing platforms cost?

Entry-level email platforms cost between £0 and about £15 a month for a small list, and the price climbs as your list or send volume grows. The figures below were taken from each provider’s UK pricing page on 23 October 2026. Check whether VAT is added at checkout, and expect prices to change.

The pricing model matters more than the headline figure. On a contact-based plan, every subscriber you keep costs money each month, even if they have not opened an email in two years. On a send-based plan such as Brevo’s, a large list that you email rarely can be cheap, but a weekly newsletter to the same list costs more. Before you choose, work out your contacts and your likely sends per month, then price both models.

What does it cost to run email marketing in-house?

Running email in-house costs a share of a salary plus the platform. The National Careers Service puts a marketing executive’s salary at £23,000 for a starter up to £50,000 for someone experienced, on 37 to 39 hours a week. Few small businesses need a full-time email specialist, so email usually becomes one part of a general marketing role.

If you do it yourself, the cost is your time. A simple monthly newsletter can take an afternoon. A proper programme, with a welcome series, segmented campaigns and monthly reporting, takes a lot more, especially in the first few months while templates and flows are being built.

The hidden risk with the do-it-yourself route is not the hours. It is that email gets dropped when the business is busy, and the list goes cold. A cold list produces more unsubscribes and spam complaints when you finally send again.

How much does outsourced email marketing cost?

Outsourced email marketing at ProntX starts from £450 a month, ex VAT, on a rolling monthly contract. That covers flows, campaigns and list growth, and you can see how we run email programmes before you talk to us. Your platform subscription is separate and stays in your name, so you own the account and the list if you ever leave.

Freelancers and other agencies price in different ways: per campaign, per day, or as a monthly retainer. When comparing quotes, ask each one the same questions:

1. How many campaigns a month are included, and who writes the copy?
2. Which automated flows will be built, and are they a one-off fee or part of the retainer?
3. Is design included, or do you supply templates?
4. Who sets up domain authentication and checks deliverability?
5. What is reported each month, and is it revenue or just opens and clicks?
6. Who owns the platform account, the templates and the data?
7. What is the notice period?

If you are budgeting across channels, our guide to what PPC costs in the UK uses the same approach of separating platform spend from management fees, and our published price list shows every ProntX service side by side.

What hidden costs push the price up?

The costs that catch people out are setup, deliverability and list quality rather than the monthly subscription. These are the ones we see most often when we take over an existing account.

Domain authentication

Mailbox providers now expect senders to prove who they are. Google’s email sender guidelines require every sender to Gmail accounts to set up SPF or DKIM, and anyone sending more than 5,000 messages a day to Gmail accounts must set up SPF, DKIM and DMARC and offer one-click unsubscribe. These requirements have applied since 1 February 2024. Setting them up means editing DNS records, which takes someone with technical knowledge an hour or two if everything is straightforward.

Spam complaints

Google asks senders to keep spam rates reported in Postmaster Tools below 0.10% and never to reach 0.30%. Going over that line can push your emails into spam folders, which wastes every pound you spend on content. Cleaning the list and sending only to people who want your emails is cheaper than repairing a damaged sender reputation.

Integrations and data

Abandoned-basket and post-purchase emails need your shop or booking system connected to your email platform. On Shopify or WooCommerce this is often a plug-in. On a custom website, it may need developer time.

Growing contact counts

On contact-based pricing, the bill rises every time the list crosses a tier. A regular clean of unengaged contacts keeps you in a lower tier and usually improves open rates as well.

What UK rules affect the cost of email marketing?

UK rules affect cost mainly by limiting how you can build a list. Under the Privacy and Electronic Communications Regulations (PECR), the ICO says organisations normally need consent before sending marketing emails to individuals, with a narrow exception called the soft opt-in.

The soft opt-in only applies when you got the person’s details while selling or negotiating to sell to them, you only market similar products or services, and you gave them a chance to opt out when you collected their details and in every email after that. A separate charitable-purposes soft opt-in also exists for charities. The ICO is clear that you must not use the soft opt-in to email people on a bought-in list.

Business-to-business email is different, but not as open as many people think. The ICO’s B2B marketing guidance says the PECR email rule does not apply to corporate subscribers such as limited companies and LLPs, as long as you do not hide your identity and give a valid address to opt out. Sole traders and some partnerships are treated as individuals. That is a large share of the market: the Department for Business and Trade’s estimates, published on 2 October 2025, put sole proprietorships at 3.2 million, or 57%, of the 5.7 million UK private sector businesses at the start of 2025.

The practical result is that buying a cheap list is rarely the shortcut it looks like. Budget instead for sign-up forms, a reason to subscribe, and opt-ins at checkout or enquiry.

What would a small business actually pay?

Here is a worked example using the prices above. Imagine a UK business with 1,000 subscribers that sends one campaign a week, so about 4,000 emails a month.

1. Platform: 4,000 sends fit inside Brevo Starter’s 5,000 emails a month, listed at £6 a month on monthly billing. On a contact-based platform, check which tier 1,000 contacts falls into.
2. Setup: domain authentication, a branded template, a sign-up form and a welcome email. If you do it yourself, allow a few days the first time.
3. Running costs: four campaigns a month, plus checking results. Whether that is your time, a share of a salary or a retainer is the biggest variable.
4. Growth: as the list grows past your plan’s limit, expect the platform fee to step up.

So the cash cost for the software can be under £10 a month, while the real cost is the work. That is why the decision about who does the work matters far more than which platform you pick.

Should you do it yourself, hire or outsource?

Choose the option that matches how much email revenue is at stake and how much time you can protect for it. Use this checklist.

• Do it yourself if your list is under a few thousand, you send monthly or less, and you are comfortable writing and editing DNS records or have someone who can.
• Hire in-house if email is one of several channels you need someone to run every day, and you can justify a marketing salary across all of them.
• Outsource if you sell online or have a large customer list, you want flows built properly the first time, and you need someone accountable for monthly results without a full-time hire.
• Whatever you choose, keep the platform account and list in your company’s name, set up authentication before your first campaign, and track revenue, not just opens.

If you run an online shop, email usually sits alongside paid search and SEO. Our ecommerce marketing work covers how those channels share one budget.

How do you know if email marketing is worth the cost?

Email marketing is worth the cost when the revenue or enquiries you can trace to it exceed what you spend on software and time. To judge that, track a small set of numbers every month.

• Revenue or enquiries attributed to email, using UTM-tagged links and your analytics (for example GA4) or your shop’s reports.
• Revenue per email sent, which lets you compare a weekly and a monthly schedule fairly.
• List growth minus unsubscribes, so you know the list is not shrinking.
• Spam complaint rate in Google Postmaster Tools, kept under Google’s 0.10% guideline.

Judge success on clicks, sales and enquiries rather than opens alone. An email that is opened but never clicked has not paid for itself.
