# Best Sales Funnel Builders 2026: Expert Picks

_2026-08-06_

You're probably feeling this already. Ads bring traffic in, landing pages look fine on paper, but the path from first click to paid customer still has too many loose ends. Some teams patch the problem with one more plugin, another email tool, or a checkout app, then spend weeks trying to make the stack behave. A better answer is a **sales funnel builder** that matches how your business sells, whether that means a fast all-in-one SaaS platform, a WordPress-native stack, or a checkout-focused tool that plugs into your existing site. For practical ideas on tightening that journey, see these [high-converting funnel tips](https://exclusiveaddons.com/how-to-build-sales-funnels/).

The UK context makes this choice more important than a lot of generic “best tools” lists admit. The UK e-commerce market reached **£127 billion** in online retail sales in 2022, according to the [Office for National Statistics benchmark cited here](https://cartflows.com/statistics/sales-funnel/), and Adobe's Digital Economy Index reported UK online sales at **41% above pre-pandemic levels by June 2020** in the same source. In a market that large and that digital, a small conversion lift can matter more than another layer of software. The question isn't which builder has the longest feature list, it's which one helps your team remove friction at each step, then test improvements without turning every launch into a technical project.

## 1. ClickFunnels 2.0

ClickFunnels 2.0 is the familiar choice for teams that want to move fast without assembling a stack from scratch. Its pricing page shows the platform as a broad all-in-one system, with funnel building, checkout, email, workflows, CRM pipelines, appointments, customer centre, and AI-assisted funnel creation all under one roof. That breadth is exactly why direct-response marketers keep coming back to it, especially when they need to spin up standard funnel patterns quickly on a UK-facing site. See the platform's own [ClickFunnels pricing and feature overview](https://www.clickfunnels.com/pricing) for the current positioning.

![ClickFunnels 2.0](https://cdnimg.co/3716ee4f-bd1a-44a8-ac85-c2df5af21725/screenshots/f8f2f673-8b1d-4b0e-9daa-e9fad672e518/sales-funnel-builders-pricing-plans.jpg)

The strength here is consolidation. When the page builder, checkout, email, and CRM live together, you spend less time fixing hand-offs between tools and more time improving the offer itself. The downside is just as clear, the workflow can feel opinionated, and the platform becomes less attractive if you want deep flexibility or you already run a WordPress-native stack that your team knows well.

### Where ClickFunnels works best

Use it when your team wants templates, speed, and a single operating environment. It's a sensible fit for agencies running repeatable funnels and for marketers who care more about launch velocity than fine-grained control.

> **Practical rule:** Choose ClickFunnels when the team needs a unified system more than a custom build environment. If your conversion problem is process fragmentation, consolidation often beats feature hunting.

For lead generation specifically, the most useful thing is not the page builder alone, it's the way the platform ties opt-in, follow-up, and checkout together. If you're comparing it with a lighter lead-gen stack, the lead generation discussion in [Otter A/B's lead generation guide](https://www.otterab.com/blog/lead-generation-in-sales) is a helpful complement because it focuses on what happens after the first form fill, not just the page that captured it.

## 2. Kartra

Kartra is for teams that want a deep marketing suite and don't mind some operational weight. Its pricing pages position it as a broad platform for pages, funnels, email, checkouts, memberships, webinars, helpdesk, calendar booking, and affiliate management. That gives it real range, especially for creators, service businesses, and mid-size teams that want native modules instead of stitching together separate apps. The official [Kartra plans and pricing](https://kartra.com/plans-and-pricing/) page is the place to check current tier structure.

What stands out is how many adjacent tasks Kartra keeps inside the same environment. You can manage a funnel, tag a lead, run an affiliate programme, and host webinars without changing systems. That helps when your business model depends on multiple touchpoints, but it also makes the interface feel heavier than a lighter page builder.

### The trade-off with an all-in-one suite

Kartra is strongest when the funnel is only one part of a broader customer journey. If you sell courses, memberships, or bundled services, the native modules can reduce integration overhead. If you sell simpler offers and only need a fast landing page plus checkout, the platform can feel like more system than you need.

The other practical point is pricing structure. Kartra's entry tiers are clear, but the plan design means you need to pay attention to quotas, fees, and how many moving parts your workflow really uses. That's important for UK teams that want predictable costs without discovering later that the “all-in-one” choice only makes sense once you use most of the suite.

> **Practical rule:** Kartra suits businesses that are ready to operationalise their funnel, not just design it. If your sales process includes webinars, support, and affiliate traffic, its native stack can save you from juggling too many tools.

## 3. Systeme.io

Systeme.io is the budget-first option that still behaves like a real sales funnel builder rather than a stripped-down trial. Its pricing page shows funnels, email marketing, automation, courses, communities, webinars, affiliate management, and file hosting, with unlimited email sends on all plans and a free plan that is unusually usable for early-stage teams. For the current setup, check [Systeme.io pricing](https://systeme.io/pricing).

![Systeme.io](https://cdnimg.co/3716ee4f-bd1a-44a8-ac85-c2df5af21725/screenshots/08dfcbac-06b2-4dbd-9678-bd1745346497/sales-funnel-builders-pricing-plans.jpg)

The appeal is obvious for startups and solo marketers. You can get a funnel live without buying a page builder, email platform, course tool, and affiliate manager separately. That simplicity makes it easy to validate an offer, and it also reduces the risk of leaving half the stack unconfigured because the team got distracted by integration work.

### Why simple setups often win early

Systeme.io is not the most design-flexible builder, and it's not trying to be. That's a strength when speed matters more than visual perfection. Teams often waste too much time polishing pages before they know whether the offer converts, and a practical funnel stack should make testing easy.

A good use case is a small UK business testing a lead magnet, a webinar, or a simple digital product. The tool gives you enough structure to launch, collect contacts, and automate follow-up without locking you into a large recurring bill before you have proof. It's also a sensible choice when the team wants fewer moving parts and can accept a simpler design system in exchange.

For a more advanced view on testing the pages that sit inside that funnel, the [Otter A/B landing page testing guide](https://www.otterab.com/blog/landing-page-ab-testing) is a useful companion because it focuses on deciding what to test, not just what to build.

## 4. HighLevel

HighLevel is the agency-first option in this list, and it shows. The platform's pricing and product pages emphasise funnels, CRM, automations, sub-accounts, white labelling, and SaaS mode, which makes it a strong fit for agencies that manage multiple clients and want to bundle services into a single system. Review the current [GoHighLevel pricing](https://www.gohighlevel.com/pricing/) page before you compare tiers.

Its real advantage is operational control across clients. You can provision workspaces, manage pipelines, and centralise follow-up without rebuilding the same structure for every account. That matters for agencies selling lead-gen retainers or appointment funnels, because the tool is as much about delivery as it is about page creation.

### When the agency model pays off

HighLevel makes sense when the software is part of your own service offer. If you're not reselling workflows, automations, or access, the platform can feel unnecessarily broad. The learning curve is also real, because there's a lot to configure before the stack feels clean.

The other issue is cost creep from usage-based add-ons. Core subscription pricing can look manageable, but telecom, AI, and other usage elements can raise the effective monthly spend if your agency runs a lot of messaging or voice-driven follow-up. For UK teams, that means you need to model the total cost of delivery, not just the entry subscription.

> **Practical rule:** HighLevel is strongest when you're running multiple client accounts and need a repeatable fulfilment system. It's less compelling if your team only wants a single funnel engine for one brand.

## 5. Kajabi

Kajabi is built for knowledge commerce, and that focus shows in the way it bundles pages, checkout, email, automations, products, community features, and course delivery. Its pricing page presents the platform as a cohesive environment for creators, coaches, and education-led businesses, so if your funnel ends in a course, membership, or coaching offer, it belongs on your shortlist. The current [Kajabi pricing](https://www.kajabi.com/pricing) page gives the clearest view of how the plans line up.

![Kajabi](https://cdnimg.co/3716ee4f-bd1a-44a8-ac85-c2df5af21725/screenshots/f09ead60-13d3-4d16-a7f4-47a24bf4ba68/sales-funnel-builders-kajabi-pricing.jpg)

Kajabi works best when the sales page and the learning experience are part of the same customer journey. That reduces friction after purchase, which matters because many creator businesses lose momentum not at checkout, but in the hand-off between sale and delivery. When the platform handles both sides cleanly, the customer sees a more coherent experience.

### Best fit for education-led offers

The trade-off is flexibility. Kajabi is excellent when your business model is centred on courses or memberships, but it is less adaptable if you run a complex direct-response funnel or a broad e-commerce catalogue. In those cases, a checkout-heavy or page-first stack often gives you more control.

For UK businesses, the practical decision usually comes down to whether the product is the curriculum. If yes, Kajabi's unified setup can cut a lot of operational drag. If not, you may end up paying for course-centred features that sit unused while your team still wants more freedom in page design, CRM, or product handling.

A useful implementation habit is to keep the offer structure simple at first, then test headline, call-to-action, and order flow separately. That way the platform does the heavy lifting on delivery, while experimentation tells you where the friction really lives.

## 6. GetResponse

GetResponse is an email-first platform that adds funnel building instead of trying to replace every part of your stack. Its pricing page shows the “Conversion Funnel” approach, with tools for lead, sales, and webinar funnels, plus email automation, pop-ups, forms, and landing pages. The current [GetResponse pricing](https://www.getresponse.com/pricing) page is the right place to check plan details, especially if your list is already growing.

![GetResponse (Conversion Funnel)](https://cdnimg.co/3716ee4f-bd1a-44a8-ac85-c2df5af21725/screenshots/9eb1ec65-11d0-434f-aecb-4f6c094e6bed/sales-funnel-builders-pricing-table.jpg)

This is a smart fit for teams that already think in lifecycle marketing. If your funnel depends on nurture sequences, webinar follow-up, and segment-based email paths, GetResponse gives you a familiar control layer. The funnel builder is useful, but the platform's real strength is the email engine behind it.

### Where it wins and where it stops

The big advantage is cohesion between capture and nurture. A lead enters through a landing page, goes into a sequence, and can be pushed towards a webinar or sales offer without leaving the ecosystem. That works especially well for consultants, educators, and B2B teams that sell through long follow-up windows.

The limitation is commerce depth. If your funnel needs sophisticated checkout logic, native cart optimisation, or advanced on-site merchandising, you'll usually need an external stack. That's not a flaw, it just means the platform is better for email-led funnels than for revenue-heavy checkout systems.

For teams that want a single environment for nurture and simple conversion paths, GetResponse is practical. For teams optimising the final purchase step, it's often better paired with a more specialised checkout or experimentation tool.

## 7. Convertri

Convertri is the speed-first choice, and the UK origin is a useful bonus for teams that want support and positioning closer to home. The platform's pricing page highlights accelerated page technology, its own CDN, funnel management, custom domains, and a WordPress connector plugin. If performance is your main issue, start with the official [Convertri pricing](https://www.convertri.com/pricing) page.

What makes Convertri attractive is how aggressively it focuses on page speed and editing freedom. It doesn't try to be a huge all-in-one suite. Instead, it gives marketers a fast way to build pages and funnels without the drag that often comes with more bloated platforms.

### Why speed-first often beats feature-first

For paid traffic, page load delays are conversion killers. Convertri's architecture is built around that reality, which is why many performance-minded marketers use it as the front end of their funnel stack. The trade-off is a smaller ecosystem and fewer built-in commerce extras, so you'll rely on integrations more often than you would with an all-in-one platform.

That's not a bad thing if your team already has an email platform, payment processor, and CRM in place. In that setup, Convertri becomes the fast layer that sits in front of everything else. If you want a lean, responsive builder rather than a system that tries to own the whole stack, it makes sense.

> **Practical rule:** Use Convertri when page speed is central to paid traffic performance. A fast page is not a vanity metric, it's often the first conversion improvement you can make without changing the offer.

## 8. OptimizePress

OptimizePress is one of the strongest choices for teams that want to own the entire WordPress stack. Its pricing page shows a WordPress-native suite with a builder, funnels, checkouts, and theme tools, so you can run the full customer journey on your own hosting. For current plan details, see [OptimizePress pricing](https://www.optimizepress.com/pricing).

![OptimizePress](https://cdnimg.co/3716ee4f-bd1a-44a8-ac85-c2df5af21725/screenshots/6f58303f-0b5f-4f85-a24a-b28d12f2b575/sales-funnel-builders-pricing-page.jpg)

The main advantage is control. You decide on hosting, you decide on updates, and you decide how close the pages sit to your UK audience. That can be a real benefit if you care about stack ownership or want to avoid SaaS variability in page delivery.

### A WordPress-native funnel needs discipline

The trade-off is obvious, you own the maintenance burden too. Hosting, updates, and security sit with your team, and if the site becomes plugin-heavy, performance can drift. You also need separate tools for some CRM and automation tasks, because the suite is not trying to be a full marketing cloud.

That said, many UK agencies and CRO teams prefer this model. They already have WordPress expertise, they want tighter control over page structure, and they don't want a SaaS subscription to determine how much they can optimise. If that describes your team, OptimizePress is a serious contender.

For optimisation work, the best practice is to keep the page architecture simple and test one element at a time. If the funnel already lives on WordPress, a lightweight experimentation layer can sit alongside it without forcing you to rebuild the whole site.

## 9. CartFlows

CartFlows is the WooCommerce-native answer for merchants who want funnel-style checkout without leaving WordPress. Its pricing page positions the tool around product pages, multi-step checkouts, order bumps, one-click upsells, downsells, and thank-you pages, all designed for WooCommerce stores. See the current [CartFlows pricing](https://cartflows.com/pricing) page for the plan structure.

![CartFlows](https://cdnimg.co/3716ee4f-bd1a-44a8-ac85-c2df5af21725/screenshots/8ea29a77-80d0-4c6b-b87e-2f3f83a512ed/sales-funnel-builders-pricing-table.jpg)

This is the practical choice if you already run WooCommerce and want to improve checkout economics instead of replacing your whole stack. You keep ownership of the site, you keep compatibility with GBP and local gateways, and you add funnel-specific conversion layers where they matter most.

### Checkout optimisation without SaaS overhead

The upside is clear. If the store is already on WordPress, CartFlows can improve the purchase path without adding another hosted platform into the mix. The risk is equally clear, because the quality of your hosting, theme, and plugin choices can affect performance.

That means CartFlows works best when the rest of the site is maintained with care. A messy plugin environment can undo the benefits of the funnel builder itself. If your stack is disciplined, though, the control and cost profile are attractive.

For WooCommerce teams, the value is often in the post-add-to-cart journey. Order bumps and upsells are not magic, they just give you more structured moments to increase order value and reduce friction. If you want a more detailed ecommerce-focused view, the [Otter A/B conversion funnel ecommerce guide](https://www.otterab.com/blog/conversion-funnel-ecommerce) is a useful next read.

## 10. Keap

Keap is the CRM-heavy option for service businesses that need pipeline management as much as they need funnels. Its pricing and product pages show multi-page sales funnels, landing pages, forms, email automation, CRM pipelines, lead scoring, appointments, and invoicing, with a strong focus on support and onboarding. The current [Keap pricing](https://keap.com/pricing) page is the place to check what's included by tier.

![Keap (formerly Infusionsoft)](https://cdnimg.co/3716ee4f-bd1a-44a8-ac85-c2df5af21725/screenshots/4f1980d7-7846-4e1c-894a-8f78485b6533/sales-funnel-builders-keap-pricing.jpg)

Keap makes sense when the funnel is really a lifecycle system. A lead comes in, gets scored, enters a pipeline, books an appointment, and later moves into upsell or retention flows. That's especially useful for consultants, agencies, and service businesses where the sale depends on timely follow-up more than on a single checkout event.

### Good for service-led revenue, less so for simple offers

The platform's biggest strength is the way it wraps automation around the sales process. That can save a lot of manual work for small teams that live in email threads and spreadsheets. The downside is price and complexity, because Keap is not trying to be the cheapest entry point or the simplest visual funnel builder.

Some UK features are more limited than the core CRM and automation stack, so it's worth checking what is and isn't available if SMS or voice plays a major role in your process. For many teams, the key question is whether they need a business operating system or just a better funnel tool. If it's the former, Keap earns its place. If it's the latter, it may be more than you need.

### A/B testing strategies for each stage of the funnel

Many teams install a funnel builder, then measure too little. The category data is blunt about that problem, because across the web roughly **570,000** websites used at least one sales-funnel-building technology, yet **68%** of companies had not attempted to measure their funnel and only **32%** were measuring it at all, according to the funnel-adoption snapshot cited [here](https://www.markinblog.com/sales-funnel-statistics/). That gap is where a lightweight testing layer like **Otter A/B** earns its keep, because it lets you test headlines, CTAs, and layouts on top of whatever builder you already run.

Start at the awareness stage with the page hero. Test a clearer promise against a more curiosity-led one, but don't change the entire page at once. On ClickFunnels, Kartra, or Convertri, this is usually the fastest win because the landing page is the first place traffic meets your offer.

For consideration, test proof and friction together. That means trying different testimonial placements, FAQ ordering, or form length, then looking at whether the page drives more clicks into the next step. On Systeme.io, GetResponse, or Kajabi, this matters because the platform may handle the mechanics well, but the copy still determines whether visitors keep moving.

At decision, test the checkout flow itself. In CartFlows, OptimizePress, or ClickFunnels, experiment with order-bump placement, button wording, and the sequence of upsell offers. For ecommerce-heavy funnels, Otter A/B is especially useful because it can tie tests to purchases, revenue, and average order value rather than just form submissions.

> **Practical rule:** Test one stage at a time, and match the metric to the stage. A better headline should improve page movement, while a better checkout should improve revenue, not just clicks.

At retention, test onboarding and first-follow-up messaging. Keap and HighLevel are strong places to do this because the post-sale workflow is built into the system. The aim is to reduce drop-off after purchase, not to celebrate a high sign-up rate that never turns into actual customer value.

The biggest mistake is testing only pages that already look good. The smarter move is to test the weakest link in the chain first, then let a lightweight tool like **Otter A/B** tell you which version improves the business outcome, not just the vanity metric.

## Making Your Choice and Starting to Test

The right sales funnel builder depends on what you sell, how technical your team is, and how much of the stack you want to own. If you want an all-in-one environment, ClickFunnels, Kartra, Systeme.io, HighLevel, Kajabi, GetResponse, and Keap each cover different levels of complexity. If you already live in WordPress or WooCommerce, OptimizePress and CartFlows give you more control, while Convertri leans into speed and page performance. The useful comparison is not “which tool is best overall”, it's “which tool removes the most friction from my specific funnel”.

The UK market context reinforces that point. The e-commerce opportunity is large, digital buying has accelerated, and a **1 percentage point** improvement in conversion can move meaningful revenue across a high-volume business base, as noted in the UK benchmark cited [earlier](https://cartflows.com/statistics/sales-funnel/). In a market like that, choosing software is only the start. The gains come from building a clean funnel, measuring it properly, and making disciplined changes one stage at a time.

For agencies and consultants, the decision often comes down to operational fit. HighLevel and Kartra work when you're delivering a service around the software. For creators, Kajabi and Systeme.io simplify launch and delivery. For merchants, CartFlows or OptimizePress often make more sense because they keep ownership close to the store. And for teams that already have a stack in place, a lightweight testing layer can be more valuable than yet another platform with overlapping features.

That's where experimentation should begin immediately after launch. Don't let a funnel sit untouched because the build felt complete. Test the headline, the CTA, the form length, the checkout flow, and the first post-purchase touchpoint. If you want a simple way to do that across almost any of the platforms above, **Otter A/B** is built for fast tests on headlines, CTAs, layouts, purchases, and revenue, so you can see what improves the funnel instead of guessing. Visit [Otter A/B](https://www.otterab.com) and start with the page or checkout step that's leaking the most value.
