What is FunnelKit plugin?
FunnelKit (formerly WooFunnels) is a WordPress sales funnel and checkout optimization plugin built for WooCommerce. Unlike CartFlows, which is also WooCommerce-focused, FunnelKit packages itself as three distinct products: the Funnel Builder for checkout and landing pages, FunnelKit Automations for email workflows and cart abandonment, and a Sliding Cart for the store frontend. You can use them together or independently.
The Funnel Builder lets you replace the default WooCommerce checkout with custom pages, add order bumps, run one-click upsells and downsells, create opt-in pages, and build thank-you sequences. It works with Elementor, Divi, Oxygen, and the native Gutenberg editor, and it ships with pre-built templates optimized for conversion. The paid Starter plan begins at $99/year.
FunnelKit Automations is the CRM-adjacent piece: it handles automated email sequences, cart abandonment recovery, broadcast emails, SMS marketing via integrations, and behavioral triggers tied to WooCommerce events. This makes it more self-contained than CartFlows for teams that also need email automation in the same stack.
The main criticism from users is that caching conflicts on checkout pages are a recurring problem, and support response times can run 12 to 84 hours for paid users — long enough to cause real problems when running paid ad campaigns. When FunnelKit works correctly, the analytics, upsell flow, and UI are considered strong. The multi-product architecture means you can pick what you need, but also means there is more to configure and maintain.

Free vs Premium
FunnelKit Funnel Builder free covers basic funnels and checkout replacement. The Starter paid plan adds one-click upsells, order bumps, A/B testing, and analytics. FunnelKit Automations is a separate product with its own free and paid tiers. Most production use cases need at least the paid Funnel Builder plan.
Common Problems & Fixes
Why is FunnelKit checkout showing incorrect product information or empty cart?
Empty cart or incorrect product display on FunnelKit checkout pages is almost always a caching problem. Checkout pages must be excluded from page caching at the server, plugin, and CDN levels. FunnelKit publishes exclusion rules for WP Rocket, LiteSpeed Cache, and other popular caching tools. Clear all cache layers, add the funnel step URLs to the exclusion list, and test with a fresh browser session in incognito mode to confirm the fix.
Why are FunnelKit upsell pages not appearing after checkout?
If the upsell step is not appearing after payment, check three things: first, confirm the upsell product is published and purchasable; second, verify that the payment gateway you are using supports one-click upsells (the gateway must store a payment token after the initial purchase); third, check the funnel rules to ensure the upsell is configured to trigger for the product purchased. Some payment gateways including PayPal standard do not support one-click upsells.
Why are FunnelKit Automations emails not sending?
FunnelKit Automations sends email through WordPress, which means delivery depends on your SMTP configuration. If your site uses PHP mail without SMTP, emails are likely landing in spam or being blocked entirely. Install a dedicated SMTP plugin like WP Mail SMTP or FluentSMTP, connect it to a transactional email provider (Mailgun, SendGrid, Amazon SES), and re-test automation triggers. Also verify that WooCommerce order statuses are triggering the expected events in your automation workflows.
Customization & Developer Notes
How do I customize FunnelKit checkout page designs?
FunnelKit checkout pages are edited through your chosen page builder — Elementor, Divi, Oxygen, or Gutenberg. Each builder has FunnelKit-specific widgets or blocks for checkout fields, order summary, express payment buttons, and trust badges. For styling beyond the builder controls, add custom CSS to your theme or child theme. FunnelKit also has a global theme setting for checkout colors and typography in the FunnelKit Settings panel.
Can I create custom automation workflows in FunnelKit?
Yes. FunnelKit Automations uses a visual workflow builder with triggers, conditions, and actions. Triggers include WooCommerce events (order placed, subscription renewed, product purchased), contact events, and time delays. You can build multi-step email sequences, conditional branches based on purchase behavior, and integrations with tools like Slack, Twilio for SMS, LearnDash, and WooCommerce Subscriptions.
Frequently Asked Questions
What is the difference between FunnelKit and CartFlows?
Both are WooCommerce funnel builders with similar core features. FunnelKit includes a more developed email automation system and a sliding cart as separate products. CartFlows focuses more narrowly on the checkout and funnel flow. FunnelKit tends to be more expensive for the equivalent feature set. The better choice depends on whether you need the automation component in the same product.
Does FunnelKit work without WooCommerce?
FunnelKit Funnel Builder requires WooCommerce for checkout, upsell, and product-related features. The opt-in page builder can be used for lead capture without WooCommerce, but the checkout optimization features cannot.
What payment gateways work with FunnelKit upsells?
One-click upsells require a tokenized payment gateway. FunnelKit supports Stripe, PayPal (PayPal Payments Pro with vault), Authorize.net, Braintree, SagePay, and Mollie for one-click post-purchase upsells. Standard PayPal does not support one-click upsells.
Is FunnelKit a good alternative to ClickFunnels?
FunnelKit is a WordPress plugin, not a hosted platform, so it requires WordPress and WooCommerce maintenance. The comparison to ClickFunnels applies mainly for businesses already running WordPress: FunnelKit gives you funnel building and email automation on your own infrastructure, without a separate platform fee, but with more technical overhead.
