The best Churnbuster, Stunning
& dunning tool alternatives in 2026
If you're researching dunning tools for Stripe, this page compares the top 5 options on features, pricing, and what they actually do well. We'll tell you when not to choose RecoverKit too — this isn't a marketing page, it's a decision framework.
TL;DR
For 90% of SaaS companies under $100K MRR, RecoverKit ($19/mo) is the right pick — AI-generated emails, pre-dunning, SMS, modern UI. Go with Stunning if you use a non-Stripe processor. Go with Churnbuster if you need enterprise SSO today. Baremetrics Recover only makes sense if you're already paying for Baremetrics analytics. FlyCode is overkill unless you're $10M+ ARR.

Detailed tool breakdowns
Each tool, explained honestly. With links to head-to-head comparisons.
RecoverKit
AI-generated recovery emails + pre-dunning for Stripe. The only tool that combines AI emails + proactive card alerts at an SMB price point. Self-serve signup, 7-day free trial, no credit card.
Churnbuster
One of the earliest dunning tools (2015). Mature, battle-tested, enterprise-friendly with SSO. Emails are pre-written templates. No pre-dunning for expiring cards.
Stunning
Long-running dunning tool (2014). Supports Stripe, Recurly, Braintree. UI feels dated. Good pre-dunning. The right choice if you're NOT on Stripe.
Baremetrics Recover
A dunning add-on bundled with Baremetrics analytics. Makes sense only if you already use Baremetrics for MRR dashboards. Template-based, no pre-dunning.
FlyCode
AI-driven dunning built for enterprise. Requires sales call, annual contracts, and a procurement-scale budget. Tech is solid but inaccessible for most SaaS.

Not all tools do the same things. Here's the feature checklist that actually matters for recovery rate:
- Multi-step sequence — one email is not enough. Minimum 3–4 touches across email + SMS over 7+ days.
- Stripe Billing Portal link — lets customers update cards in one click. Tools without this cut recovery rates in half.
- Pre-dunning — proactive alerts before cards expire. 80–90% of expired-card failures are recoverable if you ask before they fail.
- Personalization — templates with mail-merge (
{first_name}) aren't personalization. True personalization factors in tenure, plan, failure reason. - Manual review mode — ability to approve emails before they send, for high-value accounts.
- Analytics by step — which email in your sequence drives recovery? Without this, you can't optimize.
RecoverKit covers all six. Churnbuster covers four (no pre-dunning, templates only). Stunning covers four (templates only, no manual mode). The rest vary.
Frequently asked questions
What's a "dunning tool"?
A dunning tool automates the process of recovering failed subscription payments — typically by sending a sequence of emails and/or SMS messages asking the customer to update their payment method. The goal is to recover revenue that would otherwise be lost to involuntary churn.
Does Stripe have a built-in dunning tool?
Stripe has basic "send email when payment fails" functionality built into billing settings, but it's a single email with no sequence, no personalization, and no pre-dunning. It recovers 38–57% of failed payments on average. Dedicated dunning tools push recovery to 70–85%.
How much does a dunning tool save me?
For a $10K MRR SaaS, the typical savings is $200–$500/mo in recovered revenue that would otherwise have churned. The calculator (here) shows exact numbers for your MRR.
What's the ROI on a dunning tool?
At $19/mo, RecoverKit pays for itself if it recovers even one lost subscription per month. Most users see 10x–50x ROI.
