Quick Comparison Table

1. Rezoki — Best Overall

Score: 9.2/10

Rezoki is the only dunning tool that combines AI-powered email sequences with AI voice calls in a single platform. While most tools stop at email, Rezoki adds a phone call channel that reaches the 85% of customers who ignore dunning emails.

Key strengths:

• AI voice calls — The only tool in this list that calls customers with a natural AI voice. You can even clone your own voice for a personal touch.
• Bring-your-own SMTP — Use your own email server for zero email costs. Emails come from your domain, improving deliverability and trust.
• 5-minute setup — One Stripe webhook is all it takes. No complex integration, no code changes.
• Full transparency — Every action is logged in a recovery ledger. You see exactly what Rezoki did, when, and what happened.
• Historical scanning — Connect your Stripe API key and Rezoki scans your entire history for unresolved failed payments, not just new ones.
• Free tier — Start for free at up to $1K MRR with email-only recovery.

Limitations:

• Stripe-only (no Braintree, Recurly, or other processor support yet)
• Newer platform, smaller track record than established competitors

Best for: SaaS companies on Stripe that want maximum recovery rates through multi-channel outreach (email + voice).

2. Churnkey — Best for Cancel Flow + Dunning

Score: 8.5/10

Churnkey is best known for its cancel flow (the screen customers see when they click "Cancel"), but it also offers solid dunning management capabilities. If you need to address both voluntary and involuntary churn in one tool, Churnkey is a strong choice.

Key strengths:

• Excellent cancel flow builder that reduces voluntary churn
• Smart retry scheduling
• Good analytics and segmentation
• Custom email sequences

Limitations:

• No voice call capability
• Higher starting price ($100/mo)
• Emails sent from Churnkey's infrastructure, not your domain

Best for: Companies that want to tackle both voluntary (cancel flow) and involuntary (dunning) churn in a single platform.

3. Gravy — Best for High-Ticket Subscriptions

Score: 8.0/10

Gravy takes a unique approach: real human agents call your customers to recover failed payments. This white-glove service delivers excellent results for high-ticket subscriptions where each recovery is worth hundreds or thousands of dollars.

Key strengths:

• Human agents provide the highest-quality conversations
• Excellent for enterprise and high-ticket subscriptions
• Fully managed — they handle everything

Limitations:

• Expensive — custom pricing, typically 10-20% of recovered revenue
• Slow setup (1-2 weeks for onboarding and training)
• Limited hours (human agents aren't available 24/7)
• Doesn't scale as efficiently as AI-powered solutions

Best for: High-ticket subscription businesses ($200+/mo) where the cost of human agents is justified by recovery value.

4. Churn Buster — Best Email-Only Dunning

Score: 7.8/10

Churn Buster is a veteran in the dunning space and offers one of the most polished email-only dunning experiences. Their smart retry algorithms and email sequence builder are mature and well-tested.

Key strengths:

• Mature platform with years of optimization data
• Excellent email deliverability
• Smart retry scheduling
• Good Stripe and Braintree support

Limitations:

• Email-only — no voice or SMS channel
• $99/mo starting price
• Limited customization of recovery logic

Best for: Companies that want a proven, reliable email-only dunning solution.

5. Baremetrics Recover — Best for Analytics + Dunning

Score: 7.3/10

Baremetrics is primarily a subscription analytics platform, and their Recover feature adds dunning capabilities on top. If you're already using Baremetrics for metrics, adding Recover is a natural extension.

Key strengths:

• Tight integration with Baremetrics analytics
• Affordable starting price ($58/mo as an add-on)
• Simple setup and configuration

Limitations:

• Dunning is a secondary feature, not the core product
• No voice calls or advanced channel support
• Limited email customization
• No smart retry capability

Best for: Baremetrics users who want to add basic dunning without adopting another tool.

6. Stunning — Best Budget Option

Score: 7.0/10

Stunning offers straightforward dunning management at an accessible price point. It's a no-frills option that handles the basics well.

Key strengths:

• Affordable ($50/mo starting)
• Simple, clean interface
• Stripe integration
• Custom email templates

Limitations:

• Limited feature set compared to competitors
• No voice calls, SMS, or multi-channel support
• No smart retry optimization
• Basic analytics

Best for: Early-stage startups that want basic dunning at a low price point.

7. Butter Payments — Best for Retry-Only

Score: 6.8/10

Butter takes a different approach: instead of emailing customers, it focuses entirely on optimizing payment retries. Butter uses machine learning to find the perfect time to retry each failed payment, recovering revenue without any customer-facing communication.

Key strengths:

• Excellent retry optimization using ML
• Zero customer communication (some companies prefer this)
• Simple integration

Limitations:

• No email, voice, or any customer outreach
• Can only recover soft declines (insufficient funds, temporary holds)
• Hard declines (expired cards) require customer action, which Butter can't trigger

Best for: Companies that want to improve retry rates without adding any customer-facing dunning communication.

8. Stripe Built-in — Best Free Starting Point

Score: 6.0/10

Stripe's built-in dunning features are free and take minutes to enable. They provide a baseline that every Stripe user should configure, even if they plan to add a dedicated tool later.

Key strengths:

• Free
• Built right into your existing payment processor
• Smart Retries uses Stripe's massive dataset
• Customer portal for self-service payment updates

Limitations:

• Very basic email templates with limited customization
• Emails come from Stripe, not your brand
• No multi-step sequences
• No voice, SMS, or multi-channel support
• Minimal analytics

Best for: Companies just starting out that want a free baseline before investing in a dedicated tool. See our Stripe dunning setup guide for configuration steps.

Our Verdict

For most SaaS companies, the choice comes down to what recovery rate you're targeting:

• If you want the highest recovery rates possible: Rezoki. AI voice calls plus email plus smart retries, with a free tier to start.
• If you need cancel flow + dunning in one tool: Churnkey. Higher price but addresses both churn types.
• If you have high-ticket subscriptions ($200+/mo): Gravy for human-agent recovery, or Rezoki for AI voice at lower cost.
• If you want proven email-only dunning: Churn Buster. Mature and reliable.
• If you're on a tight budget: Start with Stripe's built-in features (free), then add Rezoki's free tier for email sequences.
