Which do you need?
Churnkey is the better fit if
- You want cancel flows or exit surveys for customers who choose to leave.
- You bill through Chargebee, Paddle, Braintree or anything besides Stripe.
- You want text messages, or emails sent from your own domain.
- You need a vendor with SOC 2 and a support team.
Dunity is enough if
- You bill through Stripe and failed payments are the whole job.
- A flat $29 a month suits you better than $250 or more.
- You want Slack alerts on failed payments without stepping up to Churnkey’s Core plan.
- You’d rather be set up in a few minutes with one Stripe key.
What a year costs
Both charge a fixed fee, not a share of what they recover. Here is the fee for a year of each.
- Dunity, monthly plan$29 × 12 months
- $348 a year
- Dunity, yearly planOne payment
- $299 a year
- Churnkey Starter, billed yearly$250 × 12 months
- $3,000 a year
- Churnkey Starter, billed monthly$300 × 12 months
- $3,600 a year
Churnkey’s Starter plan is for teams with less than $5,000 a month in churn volume, the revenue you churn each month. Above that, its Core plan starts at $500 a month and Intelligence at $625 a month, both billed yearly. Prices are set by churn volume and fixed for 12 months.
On failed payments alone, Churnkey has to bring back about $221 more a month than Dunity to come out ahead. Cancel flows, text messages and other billing platforms are separate reasons to pay more.
Using both at once
Dunity and Churnkey both retry failed payments and email your customer, so running both on one Stripe account means double retries and double emails.
- Pick one tool to recover failed payments. If you use Churnkey for cancel flows and Dunity for payments, check that Churnkey’s Payment Recovery isn’t also switched on for the same Stripe account.
- Leave Stripe’s Smart Retries on. Churnkey’s own docs recommend that and turning off Stripe’s failed-payment emails, and the same setup suits Dunity.
- Choose one voice for the customer email, so nobody gets two messages about one payment.

Churnkey and Dunity questions
What people ask when they’re weighing the two.
Is Dunity an alternative to Churnkey?
For recovering failed payments on Stripe, yes. For the rest of what Churnkey does, no: Dunity has no cancel flows, exit surveys, text messages or A/B testing, and it works with Stripe only. If failed payments are the whole job, Dunity does that one job for less. If you need more, Churnkey is the broader tool.
How much does Churnkey cost compared with Dunity?
Churnkey’s price depends on your monthly churn volume, meaning the revenue you churn each month. Starter is $250 a month billed yearly, or $300 billed monthly, for teams with less than $5,000 a month of churn volume. Core starts at $500 a month and Intelligence at $625 a month, both billed yearly. Each price is fixed for 12 months. Dunity is $29 a month or $299 a year, whatever you bill.
Does Churnkey take a percentage of what it recovers?
No. Churnkey’s pages say payment recovery is a fixed fee, never a take rate. Dunity is also a flat price, with no percentage of recovered revenue.
Which one recovers more failed payments?
We can’t say. Churnkey publishes recovery figures and case studies of its own. Dunity is new and has none yet, and nobody has compared the two on the same payments. What we can say is what each one does, which the table above shows.
What if I don’t use Stripe?
Churnkey works with several billing platforms, including Chargebee, Paddle and Braintree. Dunity works with Stripe Billing only.
Does Dunity send emails from my own domain?
Not yet. Dunity’s emails come from Dunity’s own sending address, and you set a reply-to so your customers’ answers reach you. Churnkey can send from your verified domain.
What Stripe access does each one need?
Both can work with a restricted Stripe key rather than full access. Churnkey’s docs recommend one, with write access to Customers, Subscriptions, Invoices, Coupons and Credit Notes, and Churnkey also offers a Stripe connection through OAuth. Dunity connects only with a restricted key, and the security page lists its eight permissions and why each is needed.
