Pricing
You pay for answers, not attempts
Start free, upgrade when you need volume. A check costs a credit only when we can give you a definite Valid or Not Valid. If the server would not tell us, the result is Unknown and it is free.
Always free, no account: single email checks and SPF analysis. API access is included on every plan, Free included - confirm your email address and create a key.
The billing rule

If we're not sure, you don't pay. That's the whole idea.
Duplicates in a file are never charged either: the same address is checked once.

Questions
Payment FAQ
What exactly is "an address"?
One email address you submit for checking, via single check, a bulk file, or the API. You're only charged if we return a definite Valid or Not Valid.
Am I charged for Unknown results?
No. Unknown means we couldn't verify the mailbox with confidence, often because the server blocks SMTP checks or uses a catch-all. We don't guess, and we don't bill for guesses.
Is my payment secure?
Payments are processed by Stripe. We never see or store your card details, they go straight to Stripe's PCI-compliant systems.
Can I cancel anytime?
Yes. Change or cancel your plan whenever you want from your account. No phone calls, no retention hoops.
Do I need a subscription?
No, the free tier works within its monthly limit without any card. Subscribe only when monthly volume makes it worthwhile.
