What Churn Buster does well

  • 10+ years of dunning email optimization
  • Transparent attribution (distinguishes incremental recovery)
  • Broad integration support (Stripe, Braintree, Shopify, Recharge)
  • Cancel flow features alongside dunning
  • Decline-code-aware email campaigns

Where Quitlo differs

  • AI voice calls as the recovery channel, not email
  • Calls within minutes of payment failure
  • Flat pricing ($349/mo) vs MRR-tiered pricing that grows with revenue
  • Structured Slack reports with failure reason, sentiment, and recovery outcome
  • Designed as an escalation layer when email fails, or as a standalone tool

Who should use what

Choose Churn Buster if you

  • You want a mature, proven email dunning platform with 10+ years of optimization
  • You need Shopify/Recharge integration (Quitlo is Stripe-only currently)
  • Email-only recovery is sufficient for your failure volume
  • You want cancel flow features bundled with dunning

Choose Quitlo if you

  • Your email recovery has plateaued and you need a new channel
  • Customers are ignoring dunning emails or they are landing in spam
  • You want AI calls for the payments email cannot recover
  • Your MRR is growing and you want flat pricing instead of MRR-tiered
  • You want both tools: Churn Buster for email, Quitlo for calls

The Quitlo Difference

Churn Buster sends emails and SMS. Quitlo calls. After 10+ years, Churn Buster still has not added voice. That is not a roadmap gap. Voice is a different product category.

Frequently asked questions

Churn Buster sends email and SMS dunning sequences. Quitlo makes AI phone calls. They solve the same problem through different channels, and can work alongside each other.

Churn Buster starts at $249/mo and scales with your MRR. At $500K MRR it reaches ~$999/mo. Quitlo is $349/mo flat regardless of MRR, or $0 upfront with 15% performance pricing.

Yes, Quitlo can stand alone. But the strongest setup is layered: Churn Buster handles the email sequence, Quitlo calls customers who do not respond to email.

Voice AI requires different infrastructure: telephony, AI conversation models, TCPA compliance, real-time handling. It is a different product category, not a feature addition.

Churn Buster flags unrecovered accounts and sends bounced-email alerts for manual merchant follow-up. Quitlo automates that next step by calling the customer directly.

Yes. Both integrate with Stripe. Quitlo is available directly on the Stripe App Marketplace.
