Do I need an all-in-one platform or separate tools?

Both approaches work. All-in-one suites reduce integration headaches and suit teams that want one system; separate best-of-breed tools give more flexibility and can be cheaper to start with. The right answer depends on your size, budget and how much complexity you can manage. This site does not recommend a specific product.

Is Google Analytics 4 free?

Yes. GA4 is the free, standard version of Google Analytics, suitable for most websites. Google also offers a paid enterprise tier (Google Analytics 360) for very large organisations with higher data limits and support needs.

Tools and platforms

Inbound marketing runs on software, and the landscape can be bewildering. This page is a neutral map of the main categories and the best-known tools in each. It is descriptive, not a ranking — there are no recommendations, scores or affiliate links here.

How to think about the categories

Rather than chase individual products, it helps to understand the jobs the software does: managing contacts and the relationship (CRM), creating and automating marketing (marketing platforms and email), and measuring what happens (analytics). Many suites span several jobs; many teams stitch together best-of-breed point tools instead. Both approaches are valid.

All-in-one inbound platforms

HubSpot — the company that coined “inbound marketing”. Its platform combines CRM, marketing automation, content management, email and analytics in one suite, aimed at small and mid-market businesses. It also runs HubSpot Academy, a large free education resource.
Marketo (now part of Adobe) — an enterprise-grade marketing automation platform, strong on complex lead management, scoring and account-based marketing. Typically used by larger organisations with dedicated marketing-operations teams.

Email and automation tools

ActiveCampaign — email marketing combined with automation and a light CRM, popular with small and mid-sized businesses for its visual automation builder.
Mailchimp — one of the best-known email platforms, historically aimed at small businesses and creators, with broadening automation and audience features.

These overlap heavily with the marketing side of the all-in-one suites; the choice often comes down to whether a team wants a focused email tool or a broader platform.

CRM

Salesforce — the dominant enterprise CRM, the system of record for customer relationships in many large companies. Its marketing capabilities are delivered through additional clouds and integrations.
HubSpot CRM — a CRM that grew up alongside the marketing platform, with a free tier that made it widely adopted by smaller teams.

The CRM is the backbone of the operation: it holds the contact records that marketing automation acts on and that lead scoring and the MQL-to-SQL handoff depend on.

Analytics and search tools

Google Analytics 4 (GA4) — the current version of Google's free web analytics, built around an event-based data model. The default tool for measuring traffic, conversions and user behaviour for most sites.
Google Search Console — a free Google tool that shows how a site performs in search: which queries bring impressions and clicks, indexing status and technical issues. Essential for the SEO side of inbound.

How tools fit together

A typical inbound stack connects a CRM (the contact record), a marketing/email platform (to create and automate campaigns), and analytics tools (to measure outcomes), with the website's CMS publishing the content that powers it all. The integrations between these tools matter as much as the tools themselves — data that does not flow between systems creates the friction the flywheel is meant to remove.

Choosing without this page picking for you

Because needs differ so much by size, budget and complexity, no neutral guide can name “the best” tool. The sensible process is to define your requirements first (contact volume, automation complexity, reporting needs, integrations, budget), then trial a shortlist. Most of the platforms above offer free tiers or trials precisely so you can test fit before committing.
