CXL Institute mini-degrees and Reforge cohort programs — the two top premium growth training platforms compared.

Take the 90-second quiz and we will route you to the right course.

Inbound Marketing Certification — HubSpot Academy

The strongest free credential for anyone pivoting into marketing or needing a recognised, CV-ready certification fast. Nine lessons across 4 hrs 53 min cover buyer personas, content mapped to the buyer’s journey, behavioural segmentation, marketing attribution and experimentation, and marketing automation with AI tools. You finish able to build a documented inbound strategy rather than just recite theory — the attribution and experimentation module is where most learners say the course earns its reputation. The exam requires a 75% pass mark and the certificate is recognised on LinkedIn, with 200,000+ professionals holding HubSpot Academy certifications across its catalog. It sits at the generalist end of the spectrum: specialists already working in a narrow lane like SEO or paid media will get more value from a more targeted certification lower down this list.

Email Marketing Certification — HubSpot Academy

Email remains one of the highest-ROI channels in marketing, and this certification treats it seriously rather than as an afterthought. Across 3 hrs 59 min and 12 lessons taught by Inbound Professor Christine Lee, you cover list segmentation, permission frameworks and deliverability mechanics, email design best practice, copywriting for conversions, personalisation and automation sequences, A/B testing methodology, and analytics interpretation. The deliverability module is genuinely underrated — most marketers learn it the hard way when their open rates quietly tank, and this course front-loads that lesson instead of letting you find out in production. The one real caveat is that the closing lesson leans on HubSpot’s own email tool as a light product demo; everything that comes before it is platform-neutral and transferable to any ESP you actually use.

Digital Marketing Certification — HubSpot Academy

The broadest entry point in HubSpot’s free library — 3 hrs 24 min across 10 lessons covering digital marketing fundamentals, consumer psychology in online spaces, ethical data practices, social media and paid ads, content marketing and SEO basics, email integration, website strategy, and a dedicated lesson on AI as a strategic advantage in digital marketing. The AI lesson is notably more practical than equivalents bolted onto paid platforms, covering real applications from AI-assisted content creation to personalised customer journeys rather than generic hype. This is best suited to people entirely new to digital marketing, career-changers returning after time away, or anyone who wants a fast, structured refresh before an interview. It will not take you to specialist depth in any single channel, but as a three-hour orientation it consistently earns its place on this list.

Content Marketing Certification — HubSpot Academy

At roughly 8 hours, this is the longest of HubSpot Academy’s core certifications, and it covers content strategy, topic clusters and pillar pages, historical optimisation of existing content, measuring performance against SMART goals, content creation frameworks, and multimedia repurposing strategy. The topic-cluster and pillar-page module is routinely cited by hiring managers in job interviews as a practical, executable framework rather than abstract theory — it is one of the few free-course modules that shows up unprompted in practitioner discussions. Free to complete, with a shareable LinkedIn certificate on completion. It pairs particularly well with the Inbound Marketing Certification above: take that one first to understand the strategic context, then take this one to learn execution. Combined, the two run under 13 hours and produce two credentials that consistently appear in growth and content marketing job specifications at the mid-level.

Social Media Marketing Certification — HubSpot Academy

A newly re-verified addition to this list: 5 hrs 18 min across 9 lessons, led primarily by Senior Professor Crystal King, who has run global social programs for companies including Keurig and Pegasystems. The curriculum covers building a social strategy from scratch, social listening and monitoring, content strategy for social channels, extending organic reach, one-to-one relationship building on social, an introduction to social advertising, and measuring social ROI. It is broader than deep — HubSpot also sells shorter platform-specific courses on Facebook, Instagram, and YouTube marketing (2-3 hours each) if you already have social fundamentals and just need one channel. As a foundation for anyone about to own a brand’s social presence for the first time, it is thorough and free, which is a combination few competitors match.

Growth Marketing Minidegree — CXL

CXL’s growth marketing track has grown substantially since it was last reviewed: as of July 2026 it spans 15+ courses and 95h 12min of material, up from the leaner roughly-40-hour version sold in prior years. The expanded curriculum now covers account-based marketing, AI-assisted ideal-customer-profile targeting, go-to-market frameworks, and partner marketing alongside the original experimentation and funnel-strategy core. Instructors include Ton Wesseling (conversion optimisation specialist), Daphne Tideman (Co-Founder of Women in Experimentation), Logan Bryant (B2B SEO consultant), Ben Labay (experimentation leader and CEO of Speero), Irina Nica (product marketing manager), and Michal Aagaard (CRO expert) — practitioners CXL says have worked with teams at companies including Lyft and InVision. Pricing has also changed shape: CXL now sells this two ways, as a standalone purchase at $999 (approx £749), or bundled into the CXL All-Access subscription at £99/month billed annually (£1,194/yr plus tax), which also unlocks the other 9 minidegrees, 100+ on-demand courses, and live cohort sessions — the better deal if you intend to study beyond this single track.

Conversion Optimization Minidegree — CXL

Still the most thorough conversion rate optimisation programme on the market, and still 20 courses across the same four tracks — Plan & Process, Assess, Test & Learn, and Decide & Act — but now running 58h 28min of material, covering how to build a culture of experimentation and get stakeholder buy-in, statistically valid A/B testing methodology, neuromarketing and behavioural design, heuristic evaluation, voice-of-customer research, and conversion copywriting. The current instructor roster is Peep Laja (CXL founder, also of Wynter and Speero), Ton Wesseling, Lucia van den Brink (Founder of Women in Experimentation), Ben Labay (Speero), André Morys (KonversionsKRAFT), and Michal Aagaard — practitioners who run CRO programmes professionally rather than teach from theory. Pricing mirrors the Growth minidegree exactly: $999 (approx £749) as a standalone purchase, or £1,194/yr on the CXL All-Access plan, which is the stronger option if CRO is one of several disciplines you plan to study rather than your sole focus.

Product Growth Foundations (formerly Growth Series) — Reforge

Reforge’s flagship growth course covers the four pillars that determine whether a product compounds: retention and engagement (use cases, habit loops, retention metrics), acquisition (growth loops versus funnels, channel strategy), monetisation (how pricing enables or constrains growth), and a unified growth model tying these together into one operating view. Built by Brian Balfour (former VP Growth at HubSpot) with contributing instructors drawn from growth leadership roles at Facebook, Uber, Pinterest, and Dropbox, the programme carries genuine weight in hiring conversations at Series B+ companies. Access requires a Reforge Individual membership, which we confirmed directly on Reforge’s own pricing page is still $1,995/yr plus tax (approx £1,495) as of July 2026 — unchanged from the previous year — and covers all 40+ on-demand courses, live cohort programmes, 600+ strategy guides, 1,400+ artifacts, and a Slack community of senior growth peers. It is a steep price for a single course, and only justified if you will use the wider library; Reforge is explicit that it is not designed for beginners, and the peer discussions inside each course assume prior growth experience.

Bottom line for July 2026

If you’re starting from zero or need a fast, CV-ready credential, the five free HubSpot Academy certifications above will take you roughly 26 hours combined and cost nothing — stack the Inbound and Content certifications first, since they’re the two most frequently cross-referenced in growth marketing job listings. If you already have a few years in the field and want a credential that carries weight with senior hiring panels, CXL’s minidegrees now offer more material than they used to for the same standalone price, while CXL’s own All-Access subscription is the better buy if you want to explore more than one specialism. Reforge remains the outlier: expensive, membership-gated, and explicitly built for people who already know the fundamentals — treat it as a Series B+ career investment rather than a first course. Prices and course scope are confirmed as of this update; always check the provider’s own pricing page before paying, since subscription-style platforms like CXL and Reforge do revise pricing periodically.
