1. ClickFunnels 2.0 — Best All-in-One Sales Funnel Builder
⭐ Overall Rating: 9.3/10 | Starting Price: $147/mo
ClickFunnels 2.0 is the gold standard of sales funnel software. Launched in 2023 as a complete rewrite of the original platform, it has matured into the most intuitive and feature-complete funnel builder on the market. Russell Brunson's team has built something that genuinely makes selling online easier. The drag-and-drop page builder is buttery smooth — everything snaps into place, and the pre-built funnel templates give you a massive head start.
What sets ClickFunnels apart is its ecosystem. You don't need to stitch together a landing page builder, an email service, a CRM, a payment processor, and an affiliate management system. ClickFunnels 2.0 includes all of these natively. For most online businesses, this means one subscription replaces 4-5 separate tools, saving both money and headaches.
Key Features

- Follow-Up Funnels: Built-in email automation with visual builders for multi-step sequences, behavioral triggers, and list segmentation. Create email campaigns that activate based on what users do (or don't do) in your funnels

- Universal Elements: Global sections that update across all pages instantly. Change your header once and it propagates to every funnel page automatically

Despite the aggressive pricing, System.io doesn't cut corners on features.

3. Kartra — Best for Advanced Marketing Automation
⭐ Overall Rating: 8.5/10 | Starting Price: $119/mo
Kartra positions itself as a complete marketing platform rather than just a funnel builder — and it delivers on that promise. Where Kartra truly shines is its advanced marketing automation engine. The visual automation builder is the most powerful of the three, allowing you to create complex, multi-branch workflows triggered by user behavior, purchase history, email engagement, and more.
Kartra includes everything: a page builder, email marketing, CRM, help desk, affiliate management, video hosting, membership portals, and a calendar/scheduling system. It's the most comprehensive all-in-one platform on this list — but that comprehensiveness comes with a steeper learning curve. Expect to spend a few weeks getting comfortable with Kartra's ecosystem.

- Kartra Calendar: Integrated scheduling system for bookings, consultations, and calls. Syncs with Google Calendar and iCal. Automate follow-ups after scheduled events
- Help Desk: Advanced ticketing system with knowledge base, customer portal, and automation rules for ticket routing and responses

Frequently Asked Questions
What is a sales funnel, and why do I need software for it?
A sales funnel is the step-by-step journey a customer takes from first discovering your brand to making a purchase — and ideally becoming a repeat buyer. Sales funnel software automates this entire process: building landing pages, capturing leads, sending follow-up emails, processing payments, and managing affiliates. Without software, you'd need 4-5 separate tools (page builder, email service, payment processor, CRM, affiliate platform) stitched together manually. Funnel software does it all in one place.
Can I use a sales funnel with an existing website?
Yes, all three platforms can integrate with existing websites. You can build your funnel pages on ClickFunnels, System.io, or Kartra and link to them from your main site. Many businesses keep their primary website (usually built with WordPress) for SEO and brand content, then use funnel software for dedicated sales pages, order forms, and upsell flows. If you need hosting for your main website, Bluehost offers optimized WordPress hosting that pairs perfectly with any funnel builder.
Do these platforms handle payment processing?
Yes, all three integrate with Stripe and PayPal for payment processing. ClickFunnels also supports Apple Pay and Google Pay. Kartra has its own payment system (Kartra Pay) in addition to Stripe and PayPal integration. All platforms support one-time payments, subscriptions, payment plans, and trial offers. Order bumps and upsells are natively supported in ClickFunnels and Kartra.
Which funnel builder has the best email deliverability?
Kartra has the best email deliverability thanks to its dedicated sending infrastructure and advanced deliverability tools. ClickFunnels uses a built-in email system that has improved significantly but still doesn't match dedicated ESPs. System.io leverages SendGrid and Amazon SES, which offer good deliverability for transactional and marketing emails. For high-volume sending, many advanced users still prefer to connect a dedicated ESP like ActiveCampaign or ConvertKit to their funnel builder.
Do I need a separate CRM with these funnel builders?
No — all three platforms include built-in CRM functionality. ClickFunnels includes a contact management system with tagging, scoring, and segmentation. System.io has a visual CRM with Kanban pipelines. Kartra has the most advanced CRM with behavioral scoring, custom fields, and detailed contact profiles. For most small to medium businesses, the built-in CRM is sufficient. Enterprise businesses with complex sales cycles may still need a dedicated CRM like HubSpot or Salesforce alongside their funnel software.
Can I run A/B tests to improve my funnel conversion rates?
Yes, all three platforms support A/B testing. ClickFunnels offers full split testing where you can create entirely different page variants and let the system determine the winner. Kartra provides advanced split testing with statistical significance calculations and automatic winner promotion. System.io supports A/B testing for pages and emails. We recommend running continuous A/B tests on headlines, call-to-action buttons, images, and pricing to maximize conversion rates over time.
Final Verdict
🏆 ClickFunnels 2.0 is the best sales funnel software for most businesses in 2026.
After 3 months of testing, ClickFunnels 2.0 delivers the highest conversion rates, the most intuitive page builder, and the best balance of features and usability.
