SubJolt vs ProsperStack: Which Cancel Flow Tool Is Right for Your Business?
SubJolt and ProsperStack both help subscription businesses reduce voluntary churn with customizable cancellation flows. The core approach is the same — intercept the cancellation, capture the reason, and present a targeted offer to save the customer.
Where they differ is pricing, session limits, and product scope. This page compares the two side by side so you can decide which is the better fit for your business.
Plan Comparison: SubJolt Pro vs ProsperStack Grow
| SubJolt | ProsperStack | |
|---|---|---|
| Monthly price | $99/mo | $200/mo |
| Annual price | $79/mo | Not published |
| Cancel sessions | Unlimited | Capped (overage: $75 per 50 sessions) |
| Free trial | 30 days | Yes |
| Free tier available | Yes — 50 sessions/mo | No |
| Setup | Self-serve, single snippet | Guided onboarding with retention expert |
| Contract | Month-to-month, cancel anytime | Month-to-month |
At $99/mo with unlimited sessions, SubJolt Pro costs less than half of ProsperStack Grow — and there’s no risk of overage charges if cancellation volume spikes. ProsperStack charges $75 for every 50 sessions beyond the plan limit, which can add up quickly for businesses with unpredictable churn patterns.
ProsperStack’s higher price includes access to a dedicated retention expert on every plan, which is a meaningful advantage for teams that want strategic guidance alongside the tool.

The key differences are in what surrounds that core: SubJolt includes on-site reactivation for churned visitors, while ProsperStack includes A/B testing and a dedicated retention expert.
Payment Gateway Support

|---|---|---|
| Stripe | ||

Where ProsperStack Wins
A/B testing. ProsperStack lets you run controlled experiments on your cancel flows to test different offers, messaging, and flow structures. This is valuable for businesses at scale where optimizing save rates by a few percentage points translates to meaningful revenue. SubJolt doesn’t offer A/B testing currently.
Dedicated retention expert. Every ProsperStack plan includes access to a retention strategist who helps with initial setup and ongoing optimization. For teams without in-house retention expertise, this hands-on guidance can accelerate results.
Broader product suite beyond cancel flows. ProsperStack also offers conversion incentive campaigns (acquisition-side), automated winback email sequences for re-engaging churned customers, a revenue recovery product for failed payments, and a free customer billing portal. These are available on the Grow plan or higher. SubJolt is focused specifically on cancel flows, on-site reactivation, and analytics.
More gateways and third-party integrations. In addition to supporting more payment gateways, ProsperStack connects to CRMs and data platforms like HubSpot, Salesforce, Segment, and Intercom. If your retention workflows depend on syncing cancel data into these systems, ProsperStack’s integration ecosystem is more mature.
AI-powered offer optimization. On the Prosper plan ($750/mo), ProsperStack offers “Autopilot” — an AI feature that automatically optimizes which offers to present based on customer data. This isn’t available on the $200/mo Grow plan, but it’s an option for businesses ready to invest at that level.
Where SubJolt Wins
Half the price, no session caps. SubJolt Pro is $99/mo with unlimited cancel sessions. ProsperStack Grow is $200/mo with session limits and $75 overage fees per 50 additional sessions. For a growing business where cancellation volume fluctuates, SubJolt eliminates the risk of unpredictable costs.
On-site reactivation. SubJolt detects churned and paused subscribers when they return to your website and displays a customizable reactivation banner with a one-click reactivation offer. This catches customers at the moment they’re already re-engaged with your site — no email open rates or click-throughs required. ProsperStack’s winback approach relies on email campaigns, which depend on deliverability and engagement.
Faster self-serve setup. SubJolt installs with a single code snippet or via Google Tag Manager. Most teams are live in about 30 minutes without scheduling an onboarding call. This is an advantage if you want to move fast or don’t need hand-holding.
Free tier to start. SubJolt offers a genuinely free Starter plan with 50 cancel sessions per month — enough for early-stage businesses to start capturing cancel reasons and testing the product. ProsperStack requires a paid plan to get started.
Sentiment analysis on write-in responses. SubJolt’s analytics include AI-powered sentiment analysis on open-ended cancellation feedback, helping you identify patterns in qualitative responses without manually reading every entry.
