Marketing automation software is sold on capability and bought on anxiety. The result is stacks of nine tools where three are used, and a monthly cost that quietly exceeds the media budget.
This is what each category does, when it becomes worth paying for, and the three tools most small businesses should actually have.

The three you probably need
1. An email platform with automation
£20 to £50 a month. This is the highest-return automation spend available, because it runs your welcome sequence, enquiry follow-up and post-purchase flows without further involvement. If you buy one tool, buy this.
The platform comparison covers which: Klaviyo for products, Kit for content, MailerLite for general small business use.
2. A simple CRM
£0 to £30 a month. Somewhere to record who enquired, what was said, and what happens next. Necessary at around twenty active prospects, when a spreadsheet stops being reliable. Pipedrive, HubSpot's free tier or Capsule are all reasonable.
3. A scheduler
£0 to £12 a month. Removes the back-and-forth of arranging calls, which is a genuine daily saving. Calendly, or your calendar's built-in booking.
What each category actually does
Email automation platforms
—Behavioural triggers, sequences, segmentation, broadcast sending.
—Worth it from your first hundred subscribers, because the welcome sequence pays for it immediately.
—Do not overbuy on list size. Pricing scales and you can upgrade later.
CRM
—Contact records, pipeline stages, activity history, task reminders.
—Worth it when you cannot remember conversations, roughly twenty active prospects.
—Enterprise CRMs are configuration projects. A small business wants something usable on day one.
Social schedulers
—Batch writing and scheduled publishing across platforms.
—Worth it if you post consistently on more than one platform. Otherwise the native scheduling is free and adequate.
Landing page and form builders
—Standalone pages and forms outside your main site.
—Usually unnecessary: your website and email platform both do this. Worth it if you run frequent campaigns needing fast page creation.
Connectors
—Zapier, Make and similar. Joining tools that do not talk to each other.
—£15 to £30 a month. Worth it for two or three genuinely useful automations; a waste if you build twelve nobody maintains.
—Check native integrations first. Most of what people build in Zapier already exists as a direct connection.
All-in-one suites
HubSpot, ActiveCampaign, Keap, GoHighLevel and others promising to replace six tools. The honest assessment:
—Genuine benefit: one system, shared data, no integration work, one bill.
—Genuine cost: each component is adequate rather than best, and you cannot replace one part independently.
—The pricing trap: the entry tier is affordable and the features you eventually need are two tiers up.
—The exit cost: migrating away means rebuilding everything at once, which is why people stay on suites they have outgrown.
I would choose a suite for a business with a sales team and a real pipeline, and separate tools for a small business where the email platform does most of the work.
What it should cost
Approximate monthly totals for a small business, as a sanity check.
—Minimum viable: £40 to £60. Email platform, free CRM tier, free scheduler.
—Comfortable: £70 to £120. Paid email, paid CRM, scheduler, one connector.
—All-in-one suite: £100 to £400 depending on tier and contacts.
—Over £300 a month for a business under £250,000 turnover: something has accumulated. Audit it.
Compare the total against your media budget. If your tooling costs more than your advertising, the stack is running the marketing rather than the other way round.
When a tool is worth buying
01The manual version has genuinely broken, not is predicted to break.
02You can name the specific job it does that nothing you own does.
03Somebody is responsible for using it. Unowned tools are subscriptions, not capability.
04The setup takes under a day. If it takes a week, it is a project and needs a business case.
05You can export your data out of it. Check this before you depend on it.
Buy the tool when the spreadsheet breaks, not when you imagine it breaking. Anticipation is how stacks reach nine tools and four habits.
What is not worth paying for
—Specialised AI tools wrapping a general model in a niche interface. You are paying twice for the same capability.
—Analytics dashboards that visualise data you already have and never act on.
—Social listening for a small business. You can read your mentions yourself.
—Chatbots nobody has configured and nobody monitors.
—Enterprise CRMs for a two-person business. The configuration cost exceeds the benefit.
—Anything on an annual plan you have used for less than three months.
The quarterly audit
01List every recurring software charge from your bank statement.
02For each: name the specific job and the person responsible. If either is blank, cancel.
03Check for overlap. Two tools that send email, two that build forms, two that store files.
04Check your tier. Most businesses sit two levels above what they use.
05Cancel first, reinstate if you genuinely miss it. You almost never do.
I have run this with clients and found £200 a month in a stack they described as lean. The wider tools stack covers the non-marketing side.
What to do instead of buying another tool
Almost every time somebody asks me which automation tool to buy, the higher-return answer is one of these.
—Build the email sequences you already have a platform for. Most businesses use 10% of what they pay for.
—Fix the follow-up speed on enquiries, which no tool solves if nobody is responsible.
—Write better copy in the automations you already run.
—Clean up the data in the CRM you already own.
—Cancel three subscriptions and put the money into creative production.
Frequently Asked Questions
What marketing automation tools does a small business need?
An email platform with automation, a simple CRM, and a scheduler. Around £40 to £90 a month covers all three.
Are all-in-one platforms worth it?
For a business with a sales team and a real pipeline, often yes. For a small business where email does most of the work, separate tools are cheaper and more flexible.
When do I need a CRM?
At around twenty active prospects, when you cannot reliably remember conversations and a spreadsheet starts failing.
Is Zapier worth paying for?
For two or three genuinely useful automations, yes. Check native integrations first; most of what people build already exists as a direct connection.
How much should tooling cost?
£40 to £120 a month for most small businesses. If tooling exceeds your media budget, the stack has outgrown the marketing.
What is the most common mistake?
Buying capability instead of using what you already have. Most businesses use a fraction of the email platform they already pay for.
Before You Go
Three tools, £40 to £90 a month, bought when the manual version breaks. Then a quarterly audit, which is the only reliable way to stop the stack growing.
And before buying anything: build the sequences your existing platform already supports. That is almost always the higher return. The workflows are here.
Three tools. Use what you have. Audit quarterly.
