Key Takeaways

- Marketing automation delivers strong returns: Nucleus Research found an average of 5.44 pounds back for every 1 pound spent.
- Brevo suits simple, budget-friendly starts; ActiveCampaign is the best all-round balance; HubSpot is the most powerful and the most to manage.

Ask online which marketing automation tool to choose and you will be buried in opinions. The honest answer is that the best tool is not the most powerful one, it is the one your team will actually use without feeling overwhelmed.
The upside is real when you get it right. Nucleus Research found that marketing automation returns an average of 5.44 pounds for every 1 pound spent, alongside a 14.5% lift in sales productivity. This guide compares the three names that come up most for UK small businesses, HubSpot, ActiveCampaign and Brevo, on the things that matter: price, ease of use, and which type of business each really suits.

First, Get Clear on What You Are Automating
Before comparing tools, decide what job you are hiring one to do. Most small businesses want some mix of:
- Email marketing and newsletters.
- Automated follow-up sequences for new enquiries.
- A simple CRM to track contacts and deals.
- Forms and basic lead capture.
If you cannot describe the workflow you want, no tool will fix that. Start with the process, as we explain in why your business needs marketing automation.
Brevo: Best for Simple, Budget-Friendly Starts
Brevo, formerly Sendinblue, is the easiest on the wallet and the gentlest to learn.
- Strengths: generous free tier, simple email and basic automation, SMS, pay-as-you-go options.
- Watch for: automation gets limited as your needs grow.
- Best for: sole traders and small teams sending newsletters and simple sequences who want to keep costs low.
ActiveCampaign: The Goldilocks Choice
ActiveCampaign is the one most often described as just right: powerful automation without enterprise complexity.
- Strengths: excellent, flexible automation, strong email deliverability, a capable built-in CRM.
- Watch for: more of a learning curve than Brevo, and pricing rises with your contact list.
- Best for: growing small businesses that take email and follow-up seriously and want room to scale.
HubSpot: Most Powerful, Most to Manage
HubSpot is the all-in-one platform with the deepest features and the biggest price range.
- Strengths: a genuinely good free CRM, all your sales and marketing in one place, scales a long way.
- Watch for: paid tiers get expensive quickly, and you can pay for power you never use.
- Best for: businesses that want one platform for sales and marketing and plan to grow into it.
A Simple Way to Choose
- Want the cheapest, simplest start? Brevo.
- Want the best balance of power and usability? ActiveCampaign.
- Want one platform for everything and room to scale? HubSpot.
In our experience setting these up for UK businesses, the regret is almost never that a tool was too simple. It is paying for a powerful platform that nobody has the time to learn.
Frequently Asked Questions
What is the best marketing automation tool for a small business? For most UK small businesses, ActiveCampaign hits the best balance of power and ease. Brevo wins on budget and simplicity, HubSpot on all-in-one scale.
How much should I expect to pay? Brevo can start free or very low. ActiveCampaign and HubSpot scale with your contact list, so costs grow as you do. Always check the price at your expected list size, not just the entry tier.
Do I need a separate CRM as well? Not usually. All three include contact management, and ActiveCampaign and HubSpot have capable built-in CRMs, so most small businesses can run sales and marketing from one place.
How long does it take to set up? A simple newsletter and a welcome sequence can be live in a day or two. A fuller setup with lead scoring and several automations takes a few weeks, mostly spent mapping your process.
