There is no single useful UK price for an email marketing agency: one quote might cover a designed campaign, another several monthly sends, and another the setup and care of automated journeys. Compare the work and responsibilities before comparing the headline fee.
To make that concrete, here are published UK examples checked on 25 September 2026. They are two providers' own offers, not an industry average, an endorsement or Ampliflow pricing. Their scope and contract terms differ, so treat the figures as reference points and confirm them on the linked pages before relying on them.
| Published offer | What the provider lists | Other terms shown |
|---|---|---|
| designbox Basic | £250 a month for one designed campaign a month | Three-month minimum and £199 one-off setup; the page says prices exclude VAT and were correct in July 2026. |
| designbox Growth | £950 a month for four designed campaigns a month | Six-month minimum and £199 one-off setup; prices exclude VAT. |
| Sarquist Media | Starts at £299 a month; its FAQ describes four designed campaigns and ongoing optimisation | Three-month minimum, then rolling; £249 one-off setup for three core automated flows. The page does not state its VAT treatment. |
Read the designbox monthly plans and Sarquist Media's email marketing offer for the providers' full terms. These examples show why “email marketing” is too broad to price on its own. A campaign, an automated-flow build and ongoing management are different scopes. This small sample cannot tell you the market average or what your programme should cost.
Separate setup, delivery and software
A first project may involve reviewing the platform and contact data, agreeing audience groups, configuring the sending domain, creating templates and building the first journeys. Ongoing work may cover campaign planning, copy, design, approvals, testing and reporting. Ask the supplier to list what is actually included.
| Part of the proposal | What to clarify |
|---|---|
| Initial setup | What already exists, what will change and what needs checking first? |
| Content and design | Who supplies product facts, offers, imagery and approval? |
| Campaign delivery | How many audiences, sends and review rounds are included? |
| Automation | Which event starts a sequence, and which event stops it? |
| Platform costs | Are software, contact storage and sending charges separate? |
| Reporting | Which business outcomes can be measured, and who supplies the sales data? |
Do not assume a campaign fee includes database repair, a website rewrite or a customer-record integration. Those may be useful, but each needs a clear scope and price. Keep platform subscription costs visible too; they can depend on the tool, contact count and sending volume.
Specify who will receive the messages
An existing customer who needs an update is different from a new prospect receiving an introduction. A previous enquiry that went quiet is different again. Those journeys may use different data, systems, creative work and safeguards.
For UK email marketing, the Information Commissioner's Office explains that PECR rules differ between corporate and individual subscribers; sole traders and some partnerships can be treated as individual subscribers. It also says using a platform does not normally transfer the sender's responsibility to that provider. Read the ICO's current business-to-business marketing guidance and electronic mail marketing guidance for the audience and method you plan to use. This checklist is for comparing work, not deciding whether a particular send is lawful.
Use the B2B email marketing guide to choose the route before requesting a quote. Ampliflow's email marketing service, B2B outreach service and database reactivation service address different starting points; do not compare them as identical packages.
Ask who owns the reply
The work has not finished when someone answers. Your team needs a named owner, a place to record the conversation and an agreed next action. A supplier may manage sending without providing a sales desk.
For example, a technical supplier might receive a request for a specification the automated sequence cannot answer. The brief should say who receives that question and what happens if they are unavailable. This is an illustrative workflow, not a client result.
Ask who approves the message, processes opt-outs and data corrections, and stops follow-up after a reply. When an agency sends messages for you, put each party's responsibilities in writing and check the current ICO guidance.
Compare proposals on one page
Send each shortlisted supplier the same brief. Record its answer beside the fee:
- Which audience and business decision does the work cover?
- What do we supply, and what will you create?
- Which systems and data have you checked?
- Who approves messages and handles replies?
- Which platform, setup or third-party charges sit outside the fee?
- What are the notice period, minimum term and exit arrangements?
- Who owns the accounts, source files and performance data?
If one proposal leaves a question blank, ask for clarification rather than filling it with an assumption. “Management” is not a specification.
Measure beyond opens
Opens and clicks can help diagnose a campaign, but neither establishes a qualified enquiry or a sale. Agree how replies, opportunities and orders will be reconciled with campaign activity. Where attribution is incomplete, the report should say so.
If you are deciding who should own the work, read the agency-versus-in-house comparison. If you are choosing between campaigns, automation and outreach, start with the B2B email brief. If the scope is clear, Get unstuck.
