Marketing Automation Software: 6 Platforms Compared for B2B SMEs

Marketing automation software all promises the same thing: more leads, less manual work, predictable growth. But the tool that works for a large SaaS company is often far too heavy, or precisely too limited, for a Belgian B2B SME. In this article we compare six platforms, with one common thread: the tool follows your strategy, not the other way around.

What does marketing automation software actually do?

A marketing automation tool takes over the repetitive follow-up work you would otherwise do by hand: sending emails automatically based on behaviour, scoring contacts as they show interest, passing leads to sales at the right moment, and reporting on what happens along the way. In other words, the tool is the engine underneath your marketing automation approach, not the approach itself. In practice, we see two companies with exactly the same tool get completely different results: the one with a clear process lets the software speed it up, the one without a process mostly automates chaos.

Do not start with the tool, start with your process

Before we name a single platform: the biggest mistake we see is companies choosing a tool and only afterwards thinking about their process. That is back to front. A marketing automation platform automates what you already do; it does not invent a strategy for you.

Not entirely sure what automation involves yet? Then first read what is marketing automation. Only after that do you choose software that fits how you follow up leads, not the one that had the nicest demo.

The features to look out for

Every tool boasts a long list of features, but for a B2B SME only five really count. Below, we set out per feature why it matters and what to look at critically during a demo or trial period.

Automation flows: the engine of your follow-up

A flow is a series of steps that runs automatically as soon as a trigger fires, for example someone downloading a whitepaper. Good flows branch on behaviour: whoever does not open gets something different from whoever clicks. During a demo, check whether you can build such behavioural branches visually without a developer. See how to build such a series concretely in how to set up a drip campaign. The mistake: flows that run purely on time (“day 1, day 3, day 7”) and ignore behaviour.

Lead scoring: knowing when a lead is warm

Lead scoring assigns points based on who a contact is and what they do, so sales invests time in whoever is ready. A simple model works better in practice than a complex model nobody understands. More in our guide on lead scoring. The mistake: scoring only on email behaviour, when a visit to your pricing page reveals far more buying intent than an opened newsletter.

CRM integration: marketing and sales on the same page

A tool without a clean CRM connection creates two separate worlds: marketing does not know what sales is doing, and vice versa. Some tools have a built-in CRM, others connect externally. Pay attention to how cleanly the sync runs, because duplicate or conflicting data undermines every flow. The practical setup is covered in setting up CRM lead management.

Segmentation: the right message to the right group

Segmentation splits your list into meaningful groups by industry, job title or funnel stage, so your message stays relevant. Dynamic segments that update themselves beat static lists you maintain by hand. Our approach: audience segmentation and segmenting your email list. The mistake: one generic newsletter to everyone.

Reporting: measure leads, not vanity numbers

Reporting should show you what delivers leads and revenue, not just how many people opened an email. A tool that calculates through to pipeline and deals is more valuable than one that stalls at opens and clicks. What you should actually track is in our lead generation KPIs. We steer on customers and revenue, and that starts with reporting that measures the right things.

All-in-one or best-of-breed?

Broadly, tools fall into two camps. An all-in-one platform (think HubSpot) packs CRM, email, landing pages and reporting into a single package. A best-of-breed setup combines separate, specialised tools: a strong email platform alongside a separate sales CRM, connected to each other.

All-in-one wins on simplicity and coherence: everything talks to everything, and you have one login and one invoice. The price does creep up, though, and you sometimes pay for parts you barely use. Best-of-breed wins on sharpness per component and on flexibility, but you are responsible for the connections yourself, and those can break. For most SMEs we work with, a light all-in-one or a well-connected duo is the pragmatic middle ground. Only move to a heavy best-of-breed landscape once your team is big enough to manage it.

HubSpot: powerful, but mind the price

HubSpot is the best-known name, and not without reason. It combines CRM, email, landing pages and reporting in one package. For B2B teams that want everything in one place, it is strong.

• Strong: everything integrated, excellent reporting, large knowledge base.
• Weak: the price rises quickly once your contact list grows or you want extra hubs.
• Who it suits: B2B companies with a growing sales team and a budget to invest in the platform.

Our honest caveat: many SMEs pay for features they never use. Do not buy more than you need.

ActiveCampaign: the pragmatic middle ground

ActiveCampaign sits in a healthy middle class in terms of price and complexity. The automation flows are visual and flexible, and the built-in CRM is light but usable for smaller sales teams.

• Strong: strong flows, good value for money, easy to learn.
• Weak: reporting is less in-depth than HubSpot, support is sometimes slow.
• Who it suits: B2B SMEs that want to automate seriously without spending a fortune.

For most Belgian SMEs we work with, this is the most pragmatic starting point.

Brevo: an affordable entry point

Brevo (formerly Sendinblue) is cheap and accessible. Ideal if you mainly run email campaigns and simple flows and do not yet need complex lead follow-up.

• Strong: sharp price, simple, strong at email.
• Weak: automation and CRM are limited as soon as your ambitions grow.
• Who it suits: starters or teams that want to test small first.

Mailchimp and Klaviyo: mind the B2B fit

Mailchimp is widely known, but leans heavily towards B2C and e-commerce. Klaviyo is excellent, but built entirely around webshops. For a B2B service provider with long sales cycles and personal follow-up, these tools are often a poor match.

• Mailchimp: fine for simple mailings, weak at B2B lead follow-up.
• Klaviyo: top class for e-commerce, not for your B2B journey.

We do not do webshop framing, so our advice is clear: do not pick a tool built for a different game.

Pipedrive with automation: when sales is central

Does your growth revolve mainly around an active sales team? Then a sales CRM like Pipedrive with automation add-ons can make more sense than a marketing platform. You keep the focus on deals and follow-up, and add automation where it genuinely helps.

• Strong: sales-driven, clear pipeline.
• Weak: marketing features are supplementary, not the core.
• Who it suits: B2B teams where the salesperson is the engine, not the campaign.

How to align CRM and marketing is covered in CRM marketing.

How do you choose based on your situation?

There is no “best” tool, there is only the tool that fits your situation. Three questions quickly point you to the right camp:

• How do you follow up leads today? If everything still sits in scattered mailboxes and Excel, start light (Brevo, ActiveCampaign) and build out. If you already work in a structured way, a heavier platform can pay off.
• Who is the engine of your growth? If everything revolves around an active sales team, a sales CRM with automation often fits better than a marketing platform. If it revolves around content and campaigns, a marketing-first tool makes more sense.
• How much time and budget do you have to manage it? A more powerful tool is only powerful if someone manages it. A small team is often better off with fewer features it actually uses than with a suite that mostly gathers dust.

Our honest advice: choose the smallest tool that runs your current process neatly, and only move up once you hit real limits. Not sure whether you are ready to automate yet? Then read marketing automation for B2B.

Common mistakes

The same errors come back time and again, regardless of which tool companies choose:

• The tool first, the process second. You automate a process that does not exist, and the expensive software changes nothing about your result.
• Over-buying. An enterprise package while you run five flows: you pay for features you never touch.
• Steering on vanity numbers. An open rate of 40 percent means nothing if no lead or deal comes out of it.
• Neglecting the CRM connection. Without a clean sync, marketing and sales drift apart.

The tool is 20%, the approach is 80%

The best software delivers nothing if your flows, your message and your follow-up are off, a pattern that also shows up in this overview of marketing automation software. We steer on customers and revenue, not on the number of emails sent or newsletters opened. Those vanity numbers say little about your growth.

That ratio makes clear in a single image where your attention belongs: not on the tool’s buttons, but on the process underneath.

When we overhauled the entire approach for Get Driven, the gain did not come from a fancy tool, but from a sharper process and better conversion. The software was the final piece, not the starting point.

Frequently asked questions

What is the best marketing automation tool for a B2B SME?

There is no universal winner. For most Belgian B2B SMEs, ActiveCampaign is a pragmatic starting point: strong flows, a reasonable price and a light built-in CRM. Those who want everything in one place and have the budget look at HubSpot. Those who want to test small start with Brevo. The right choice depends on how you follow up leads today and who the engine of your growth is.

What does marketing automation software cost?

Prices vary widely and scale with your number of contacts and the features you switch on, so naming a fixed amount would be misleading. The general rule: entry-level tools are affordable, but costs can rise sharply once your contact list grows or you activate extra modules. So always calculate with your expected list size a year out, not with today’s entry price.

Can I set up marketing automation myself or is it better to outsource it?

That depends on your time and in-house knowledge. Learning the tool itself is doable, but the strategy behind it (which flows, which message, which follow-up) determines whether it works. If you do not have that time, outsourcing marketing automation explains what a partner can deliver for you.
