The principle behind the list

Every tool on this list is free (or has a genuinely useful free tier). More importantly, each one solves a specific, critical problem that every marketing-active business has, regardless of size. This is not a list of nice-to-haves — it's the list I'd set up on day one for any client who asked.

I've seen startups spend $2,000 a month on a marketing stack before they've established whether their message resonates. I've also seen solo consultants generate meaningful pipeline from nothing but the five tools below. The difference was never the tool — it was the clarity about who they were marketing to and what they wanted those people to do.

The right tool for your stage of growth is the simplest one that removes the specific friction you have right now. Complexity comes later, if at all.

1. Google Analytics 4 + Search Console

What it costs: Free.

What it does: GA4 tells you who visits your site, where they came from, and what they do when they get there. Search Console tells you what keywords your site is ranking for and how many people click through from Google. Together they are the essential picture of your digital marketing performance.

Why it's first: you can't improve what you can't measure. Before you spend any time or money on marketing, install GA4 and connect Search Console. Set up at minimum two conversion events: form submission and any resource download. Without this, you'll spend months optimising based on gut feeling.

Setup time: 2–3 hours including Google Tag Manager setup. Worth every minute.

What to ignore when starting: almost everything in GA4 except Sessions, Conversions, and the Pages report. The depth of reporting in GA4 is enormous. Start with three numbers and build from there.

2. Canva

What it costs: Free tier is genuinely sufficient for 80% of use cases. Pro ($20/month) adds brand kits and unlimited templates.

What it does: Canva is a browser-based design tool for people who are not designers. LinkedIn carousel slides, social graphics, ebook covers, pitch decks, presentation templates — all of it, without touching Illustrator or InDesign.

Why it's second: every marketing channel produces better results with consistent, on-brand visual assets. Before Canva, this required either a designer or hours of learning a professional tool. Now it requires a template and 10 minutes.

The highest-leverage use: build one template for each content format you use (LinkedIn carousel, story graphic, blog header, ebook cover) and reuse it consistently. Consistency in visual identity builds recognition faster than variety.

3. ConvertKit or MailerLite

What it costs: both are free up to 1,000 subscribers. ConvertKit's free tier includes basic automation; MailerLite's is slightly more limited but the paid tier is cheaper if you grow beyond 1,000.

What it does: email marketing and list management. A subscriber form for your site, an automated welcome sequence, and a newsletter send tool.

Why it's third: your email list is the only marketing asset you own outright. LinkedIn can change its algorithm. Google can update its policies. Your email list goes nowhere unless you burn it. Every other channel you build should be feeding this one.

The minimum setup: one form on your site offering something useful in exchange for an email address (a checklist, a guide, a template). One automated welcome email that delivers the resource and explains what you'll be sending. One weekly or fortnightly email that provides one useful insight. That's a functional email marketing operation.

4. Typefully

What it costs: free for basic scheduling. Pro ($12.50/month) adds analytics and multi-platform scheduling.

What it does: LinkedIn (and Twitter/X) post scheduling and analytics. Draft posts, schedule them for optimal times, see which ones perform.

Why it's fourth: if LinkedIn is part of your marketing strategy (and for most B2B businesses it should be), having a scheduling tool lets you batch your content creation instead of scrambling to post daily. The analytics tell you which content formats and topics resonate with your specific audience — data you can't get from LinkedIn's native analytics without a premium account.

The workflow: Monday morning, draft the week's LinkedIn posts. Schedule them for Tuesday 8am, Wednesday 8am, Friday 8am. Done. The rest of the week, engage with comments and messages — the actual relationship-building part of LinkedIn — without the cognitive overhead of "what should I post today?"

5. Calendly

What it costs: free for one event type. Standard ($12/month) adds multiple event types and integrations.

What it does: online appointment booking. Share a link → other person picks a time from your available calendar → meeting is booked, confirmed, and added to both calendars automatically.

Why it's fifth: if you sell services, every extra step between "I'm interested" and "we have a meeting" is a conversion leak. Email back-and-forth to find a time loses roughly 40% of warm leads who never reply to the second email. Calendly removes all of that. Your contact page or services page has one link. People book. You show up.

The setup: create a "30-minute free consultation" event type. Add 2–3 qualifying questions to the booking form ("What's your biggest marketing challenge right now?"). Add the link to your contact page, your email signature, and every "Book a call" CTA on your site. This is a 30-minute setup that will save you hours every month.

The $0 stack in practice

With the free tiers of all five tools, here's what you have:

This is a complete, functional B2B marketing operation. It is not the most sophisticated stack — but it is the most leverage-per-hour stack available at zero cost. Start here. Add complexity only when this is running consistently and you've hit a specific ceiling that a more advanced tool would remove.
